HyperMesh 14.0.120 Release Notes

General

Mechanism Tool

The Mechanism Tool, available in the RADIOSS and LS-DYNA user profiles, enables the modeling of kinematic systems by the definition of kinematic assemblies (bodies) and kinematic joints. The definition of the mechanism is made in a dedicated browser, with the Entity Editor for the related mechanism entities (Mechanism, Body, Joint, Constraint). The usage of manipulators offers a powerful user interaction with the mechanism.

This tool is especially useful for seat mechanism application, for which a kinematic coupling with a dummy is possible. The Mechanism Tool can also be used to model any kind of kinematic system.

Dummy Positioner

A new Dummy Positioner is available in the RADIOSS and LS-DYNA user profiles, to position a dummy interactively. The dummy positioner is now integrated in a new browser, with interactive manipulation of the joint from the graphics. The Dummy Positioner is compatible with all LS-DYNA and RADIOSS Humanetics dummies (encrypted or not) and also with LSTC LS-DYNA dummies.



ID Manager Updates

• XML comments and CSV Support

Import and export of ID Manager rules as XML comments in the solver deck is now supported. A new ‘ID Rules’ check box is added in both Import and Export browser tabs as well as in the Include View when you export an include file or all includes.

The XML comments are written as a separate block at the end of a solver deck similar to connectors XML comments export.



You can also save ‘ID Rules’ in a CSV file directly from the ID Manager dialog. This new setup is available in the context menu of ID Manager Dialog. Both Import and export of CSV file is supported.

• Filtering Includes and Hiding Excluded Entities

The ID Manager dialog has added a Filter include file button that enables you to set a filter on the available includes. The filter button will dynamically update the status from default OFF to ON when filtering is applied.

You can also now hide excluded entities in the ID Manager dialog. The check box works across the includes and hide entities from the dialog if they are shown as excluded entities.

Both Include Filtering and Hide Excluded Entities settings can be saved and read using the HM model and the solver deck, respectively.



Before applying Filter Include and Hide Excluded Entities settings

After applying Filter Include and Hide Excluded Entities settings

• Ability to organize associated elements while organizing solids geometry

• Warning message setting inside Entity editor for change in card image is now off by default



Undefined Entity Support

Undefined Entity support is extended to Sets and Curves for all applicable User Profiles. In addition, a warning message is displayed in the Import Process Messages dialog on the import of a solver deck containing referenced entities.

Undefined Entities

The import and export of referenced entities is fully supported for properties, materials, sets and curves. HyperMesh creates the appropriate entities and assigns a default Card Image upon import of a solver deck containing referenced entities. In addition, a warning message is displayed in the Import Process Messages dialog on the import of a solver deck containing referenced entities.

Undefined entities exhibit the same behaviors as defined entities; they are visible in all relevant browsers and in the Entity Editor. The defined state, attributes, and Card Image can be modified as per requirements of the user.

The renumbering of undefined entities is restricted to ensure references to entities that reside in external Include files will not be invalidated.

Undo/Redo

Enhanced Undo Redo support which now includes additional panels, browser operations and improved messaging.

DDAM Support

DDAM interface has been enabled via the OptiStruct user profile.

Include Export Options

The ability to control comments – HM, ID Rules, Part Assembly/Part, Connectors – has been added within the include export operation from within the Browser Include view. These same options are available via the standard export.

"Move to Include"

The Move to Include capability is now supported for the RADIOSS user profile in addition to Ls-DYNA. The capability enables the component and all of it’s referenced and cross referenced entities to be organized (moved) to the selected include or new include.



Organize Associated Elements Related to Solids

In the Organize panel, you can now select to organize the solid elements associated with solid geometry.

Part Replacement Updates

Several updates were added including improved handling of meshless welds (connectors), improved messaging, better support for *PART_COMPOSITE replace plus the resolution of several issues including the direct property assignment to solid elements being lost post part replace.

Miscellaneous

• Count panel

The Count panel now has new widgets for counting topo points (vertices) and topo lines (surface edges). This is in addition to the existing widgets for counting free points (points) and free lines (lines).

• Improved Accuracy for mass calculation

New FIND CONNECTIVITY tool available to identify portion of a model that are not connected

Resolved Issues

• Missing option related to connector’s comments while exporting an include file.

• Saved Views in the browser are getting messed up after renumbering and reordering components.

• Preserved nodes are unexpectedly getting selected during any nodes selection operation.

• Organizing a component to an include is not working consistently.

• Deleting unused sets from delete panel also delete the rigid bodies.

• Application crashes while using hm_createmark API for curves.



• Model Checker rerun automatically if you clear the session and reload the model again in the same session.

• Export an include with relative path crashes the session.

• Mass value of individual Include file imported with master is showing wrong value.

• Fixed a refresh problem in the Solver browser that was not listing a newly created system.

Model Build & Assembly

The Common Model workflow has been significantly enhanced with respect to Representation Management and Configuration Management.

Representation Management Enhancements include the one click generation of all representations, the introduction of the Representation Settings dialog for organization of user defined representations and an Add Representation workflow which allows automatic loading of added representation added in bulk and the filtering of associated representation files.

Configuration Management Enhancements include the introduction of two new HyperMesh entities, Part Sets and Configurations, the former facilitating the logical grouping of Part Assemblies and Parts and the latter facilitating the creation of user defined configurations. In addition, the introduction of multi-pane views and an intuitive drag and drop workflow in the Part browser simplifies the creation and organization of multiple configurations in a single HyperMesh binary file. Figure 1 shows a sample BIW subsystem with multiple configurations.

Figure X: BIW Configurations

The image below shows Configuration multi-pane view in Part Browser for the BIW model.

Connectors

CWELD Visualization

On the visualization tab in the connector chapter a special CWELD visualization can be activated. The graphical representations reflect the different CWELD definitions.



Link Option Closest vs. Opposite for Area Connectors

The opposite link option has been utilized for the area connector realization. If activated it ensures, that to both sides of the connector the closest link candidates are connected. The parallelism of the opposite links is check and controlled by the definable normal projection deviation angle. This option helps to realize in the desired way, if the seam is not precisely positioned in the middle of the connected parts.

Absorption Enhancements

The complete absorption has been performance improved. Along this update couple new mechanisms have been implemented:

ACM (general):

All regular ACMs will be absorbed as ACM (general) now. During the absorption three versions are differentiated (shell gap, equivalence (T1+T2)/2), constant thickness). The connector get the appropriate attributes assigned, which allows the same rerealization.

For certain situations there isn’t a clear identifier between shell gap and equivalence (T1+T2)/2. The new option If hexa thickness type is ambigous decides about the preference.



Solid seams and areas:

The absorption of solid seams and area connectors can be more precisely controlled. It is clearly differentiated between seams and areas, as well as between with head and without head.

Convert Connector Style Enhancement

In the context menu of the Connector browser, connectors of one specific style can be converted into another one. This has been enhanced in a way, that additionally any connector lines can be converted to seam connector lines and vice versa.



Convert settings control, if line connectors should remain as line connectors after the conversion or if they are going to be converted to single point connectors pro each connector point.

Combine Connectors

In the context menu of the connector browser aligned single point connectors can be combined into line connectors of the same style or several aligned seam line connectors into larger one(s).

In the combine settings an angle and a distance is defined, which describe the conditions for combining single point connectors.



Split Connectors

In the context menu of the Connector browser, spot or bolt line connectors can be split into individual single point connectors.

In the Split settings, it can be decided if the connectors should be unrealized along with the split.



Position Connectors

In the context menu of the Connector browser spot or seam connectors can be positioned to the center position between the defined link candidates. The source position is stored on each individual connector; hence moving back to the source position is possible, too.

In the position settings the selected connectors can be filtered down with respect to certain attributes.

The position function works for single point as well as for line connectors.



Automatic Number of Layer Detection

In the Spot panel for connector creation and realization the number of layers can be set to auto now. The precise number of layers will be detected during the link detection process and saved onto each individual connector. A reasonable tolerance is essential, when using auto for the number of layers.

Consistent Connector ID Handling During Import

For connector import overwrite and ID offset is supported now.

Resolved Issues

• Looped seam connectors created by nodepath were only visually closed.

• Weighting factors for the ACM (general) realization with radius option and normal distribution was wrongly calculated.

• Inactive components weren’t ignored during absorption.

• For CWELDs GS (point to face) the GS node wasn’t equivalenced to the link.

• The connector XML import for big area connectors led to a crash.

• Several attributes in the Connector Entity Editor were not available.

• In certain cases bad hexa elements have been created for adhesive seams in combination with discontinuity.

• Seam snapping behaved wrong in some scenarios.



• For more complex shapes the area connector has been created wrongly.

Geometry

Dimensioning

The Dimensioning tool has undergone significant changes to improve the workflow and the usability.

A new Feature entity has been added, which allows defining, storing and manipulating relevant geometric dimensions in the model from within the browser, and via Tcl APIs. In addition, dimensions can also be parameterized via the parameter entity, as well as linked together via parameter entity expressions. This allows for easy design optimization iterations with HyperStudy. Previously, the dimensions only existed and could only be controlled within the Dimensions panel.

General improvements have also been made to the robustness of the tool.

Geometry Match Topology

This tool, accessed from the Geometry menu, fixes gaps between stitched edges and vertices to make the actual geometry of the surfaces consistent with the model topology. It checks the topology of the model for gaps that are larger than a given tolerance between shared, non-manifold, or suppressed edges. If a gap is found to be bigger than the specified tolerance, then the surface and edge geometries will be morphed parametrically and in 3D, if necessary, to make the gap smaller than the tolerance. In addition, non-essential degenerate edges are removed.

Trim with Lines

In order to increase the performance of the Surface Edit > Trim with Lines > With Lines panel for aerospace use cases where many free lines are being used to trim surfaces, a few improvements have been made:

• Implemented choices for the type of line to use as input, so that the user can easily select only free lines (default), only surface edges, or any lines.

• Changed the default maximum projection distance to match the geometry cleanup tolerance (previously the default value was zero).

• General improvements to the trimming performance.

When utilizing these options together, improvements on the order of 30-40% may be seen.

Surfaces Normal from Edges

A new subpanel Surfaces > Normal from Edges has been added. This allows the creation of surfaces by dragging lines along the normal of their adjacent surfaces. This is useful for creating ribs and spars in aerospace models.



For shared and non-manifold edges, the surface normal is taken from the surface of the master edge. In the event the neighbor surfaces are tangent enough to each other, the average normal is instead used. Adjacent surfaces are properly trimmed and stitched together to allow for a simple one-step process.

Miscellaneous

• The geometry feature angle can now be specified between 0-180 degrees for face selection, instead of being limited to 0-90 degrees.

• The duplication of surfaces now properly maintains any suppression of fixed points from the original surface to the duplicate.

• Metadata is now maintained and propagated when performing surface offset and dimensioning.

• Suppressed lines are now supported for selection "by path".

• The Surfaces > Meshline subpanel has been fixed to resolve multiple issues and crashes.

Resolved Issues

• Resolved an issue with CAD metadata handling causing a crash on HyperMesh binary save and/or load. After merging two or more CAD files containing metadata into the same session, saving the HyperMesh binary file would potentially result in a crash. If the save was successful, those files would potentially crash upon load. These issues have all been resolved. Any existing binary files that exhibited the crash due to this issue can also now be successfully loaded.

• Resolved an issue where under certain conditions, an invalid topology was created during CATIA composites import. This would potentially lead to a crash upon saving or loading the HyperMesh binary file. These issues have all been resolved. Any existing binary files that exhibited the crash due to this issue can also now be successfully loaded.



• When trimming surfaces that had suppressed edges, sometimes the suppressed edges would become unsuppressed, or would have vertices created at the trim line locations. These issues have both been resolved.

Meshing

BatchMesher

• Updates have been made to improve the meshing of flanges. These include:

− Suppressing unnecessary input edges to improve mesh flow − Preventing the addition of unnecessary trim lines that may disturb mesh flow − Removal of narrow elements that disturb the mesh flow − These enhancements do not require any changes to the param file

• The ability to defeature fillets has been added to the surface fillet table. This allows for the removal of fillets that fall within certain ranges. Additionally, special geometry cleanup is performed after defeaturing in order to cleanup any unstitched edges, and to patch any holes or gaps.

• Plot elements associated to surface edges are now maintained and used for connectivity within BatchMesher, instead of being deleted. Other 1D element configs were previously supported.

• When the mesh type is set to trias, the meshing of rectangular surfaces no longer results in a majority r-tria mesh.



• Miscellaneous minor bug fixes related to the feature recognition and capture of beads, fillets and holes.

Geomechanics

A new detach capability, useful for creating faults for geomechanics, has been added which allows detaching elements from the nodes of wall elements. This is available via the Detach > From Wall subpanel.

The elements surrounding the wall must be one dimension higher than the wall elements. The elements surrounding the wall can be classified as belonging to different clusters based on which side of the wall elements they appear. For each cluster of elements attached to the wall, the shared nodes are duplicated after detachment.

Options are also available for offsetting the nodes of the detached elements, as well as also detaching the free ends of walls.

Seed Node Based Volume Selection

The Volume Selector in mesh controls allows you to select volumes based on enclosed seed node. You can define fluid volume and solid volumes by selecting enclosed seed node. Also, you can define which volume should be skipped by selection enclosed seed node.

You can also define index of the volume to be meshed as largest, 2nd largest, etc.

Elements Based Surface Deviation in Panel

The Surface Deviation method for element remeshing can be accessed now via the Automesh panel. It captures curvature and provides smooth transition from small size elements to big size elements. A new mesher internally identifies the elements features based on defined feature angle and captures/refines them.



New Imprint Panel Options

• Option to create patch in imprint:

A new is available in the Imprint panel which creates a patch between imprinted edges. This enables you to retain the inputs as they are and create patches in-between rather than merging them.

• Option to select nodes as source:

You can now can select nodes as source in the Imprint panel. This enables you to imprint nodes on edge to imprint on element faces without creating 1D elements.

Miscellaneous

• Added support for bar3 element creation in the Line Mesh and Linear 1D panels.

• The Preserve Edges tool can now be accessed directly from the Autocleanup panel and the Automesh > batchmesh/QI subpanel.

• Element normals can now be adjusted using a reference vector direction within the Normals panel.



• The connectivity between 2D element edges and 1D/3D elements can now optionally be maintained in the Elem Cleanup panel.

Resolved Issues

• Mesh controls feature-based meshing issues related to several crashes, incorrect/incomplete fillet meshes, and mesh connectivity problems when using standalone feature-based meshing (without other HyperMesh mesh controls) have been resolved.

• When creating a mesh in the Line Mesh panel and specifying an orientation node, all beam elements in the model were being updated to have this orientation node. That has been resolved.

• When using QI or BatchMesher meshing with the mesh type set to trias, the meshing of rectangular surfaces no longer results in a majority r-tria mesh.

APIs

CAD Import and Export

All CAD import and export options can now be specified on the command line via the new *geomimport and *geomexport commands, as well as within the respective .ini files. This allows for complete customization of the CAD import/export behaviors from within a Tcl script.

When legacy commands *geomoutputdata, *geomoutputdata2, *iges_write or *iges_write_units are executed via scripts, *geomexport will be written to the command file instead.

Command File

The HM_COMMANDFILE_MODE environment variable has been enhanced. When using UNIQUE mode, the user name is now also included in the command file name, to further guarantee uniqueness and to allow for better traceability.

Face/Edge Selection and Node Lists

New options have been added to *createmarkpanel and *editmarkpanel:

• New node face/edge selection modes free edges ext (6) and edge ext (7) for face_edge_mode.

• New filter option for specifying only specific selection modes to allow.

In addition, hm_formnodelistsfrommark has been added for converting a mark of nodes into one or more node lists.



Thin Solids

A new API hm_getgeometricthinsolidinfo has been added for finding thin solid geometries, and returning information such as the estimated thickness and the master, slave and thickness surfaces.

Decimation

Decimation APIs has been added to this version. Decimation APIs enables you to decimate (coarsen mesh) while retaining topological shape as it is while reducing element count. It will automatically detects curvatures and retain them. A new capability to define localized wrap settings via the Mesh Control browser is available. Local controls will take the precedent over global settings.

Resolved Issues

• Resolved an issue with the hm_framework removetab API in HyperMesh Desktop. Previously, any user-created frame would be destroyed during this call. This was inconsistent with HyperMesh standalone, where the frame would not be destroyed. An additional flag has been added to support also keeping the frame for HyperMesh Desktop.



HyperView 14.0.120 Release Notes

Highlights

Highlights of this release include an addition of a new measure type to compute shortest distance between two entities, graphical in-place editing of legend, a new graphical slider on the legend for iso-plots, and some general enhancements and bug fixes.

Minimum Distance Measure Type

A new measure to calculate the shortest (minimum) distance between any two entities during a simulation is added. The entities can be nodes, elements, or components. If elements/components are picked on the “To” side, HyperView will take into account the surface of the element when calculating the shortest distance. As the animation is played, the graphics will be updated to show the shortest distance. Additionally, users can plot this measure in a HyperGraph window similar to other measure types.

For fastest calculation, use node sets. If more accuracy is desired, pick element or component sets and in this case, the time taken to calculate distance through one cycle of animation is directly proportional to the size of the sets.

General In-Place Legend Editing

The HyperView legend is enhanced to allow users to edit values and colors of the legend by just clicking on it and changing it in-place instead of using the Edit legend dialog.

A context menu is also available on right clicking the legend, to let users modify other attributes of the legend such as format, location etc.



Graphical Iso-Slider On Legend

This enhancement gives users a quick and convenient way to create & control iso-plots. Simply use the legend context menu to add an iso-plot that is based on the contour settings and then move the graphical slider on the left side of the legend up and down to control its display. The threshold value and mode of the iso-plot can be changed in the Iso section of the legend.

General Enhancements

• HyperView Player is enhanced to allow users to change the animation mode (e.g. transient to modal or transient to linear).

• Utility to extract assemblies from LS-Dyna input deck is enhanced to support include files.

• New report template parameters for parametrizing display attributes such as mesh mode and views at a model level is provided.



• New preference menu option to retain the rotation center even when it is moved off the screen is added.

Resolved Issues

• Differences in contour plot display between HyperView and HyperView player due to absence of accelerated graphics option in the player. Accelerated graphics is now enabled in HyperView player.

• Max of Window template expression in Note does not provide correct results when results with corner data is plotted.

• Notes when exported in a H3D come back on top of each other on re-import.

• Time Synchronization information is not saved for videos.

• Graphics issue when section cut is created on solid elements.

• Edge lines are shown on wrongly connected Penta6 elements.

• Long time to open model files containing a large number of duplicate nodes.

• Application error when opening H3D files with non-English characters in the path or file name

Solver Interfaces


• UNV reader enhanced to read Nodal Stress Results

• OP2 reader enhanced to read intermediate results from Nastran SOL400 analysis

• LS-Dyna reader option added to support decreasing time (e.g. Implicit Simulation)

• OP2 reader enhanced to read results from NX Nastran SOL111 analysis

Resolved Issues

• Incorrect values when plotting complex results on composites in OptiStruct op2 file.

• Application hang when plotting composite stress/strain results in OP2 Results file.

• Incorrect Composite strain results shown when plotting Abaqus ODB files



HyperGraph 14.0.120 Release Notes

Highlights

The HyperGraph Plot browser is updated with a new string-based filter, which supports keyword-based searches and Boolean operations. This allows filtering using entity properties of curves, axis, etc. in combination with newly introduced page and window properties. Particularly, the editing of large session files will become much easier. Drag & drop has been added to the plot browser for faster repositioning of curves, together with new context menus to isolate / reverse-isolate curves.

CSV files can be loaded as documents in TableView so that they appear as parameters in report templates, similar to the open document feature in TextView. Using overlay areas in TableView allows the user to append rows or columns with cell values from CSV files by overlaying report templates.

PowerPoint Publishing allows more control with respect to defining the size of the exported images or movies on Windows. As was implemented for LINUX in the previous release, an algorithm was added to keep the image aspect ratio when synchronizing modified PowerPoint presentations. New APIs are added which allow customization of all PPT Publishing features.

Plot Browser

• String-Based Filtering: The string-based filter functionality allows the user to add keyword-based searches and Boolean operations; braces can be used to modify the search string. Keywords and search values for all entity properties can be graphically added by using the context menu in the property tables. Previous searches are stored in the drop down list and can be reused within the current session. The combination of entity and page/window properties make it much easier to handle large files. Typical examples would be searching for all horizontal axes in XY plots, and ignoring bar charts and complex plots



• Drag & Drop: The Plot browser curve view now supports dragging and dropping of curves, which is a faster way to perform the existing cut-paste feature. This allows easy positioning of multiple curves behind a dedicated curve, which was previously only possible for single curves in the Define Curves panel.

• Isolate/Reverse-Isolate: Similar to HyperView, the Plot browser now allows isolate / reverse-isolate only in the curve view. Because the Plot browser allows selections over multiple pages and windows, the options “per window”, “across pages” and “across session” are added. Using “per window” will only isolate curves in windows where at least one curve is selected; all the other windows will not be affected. “Across page” works similarly for the entire page. If the user wants show only the selected curves for the whole session, “across session” needs to be selected. Isolate only will show only the curves; all other entities (notes, axes, headers etc.) will be hidden



• Page / Window Properties: The following new page and window properties are accessible in all views of the Plot browser and can be used for filtering:

TableView - Support for Excel CSV Documents

By loading CSV files via File > Open > Document into TableView, a link to the Excel file is saved to the session file or the report template. Changes to formatting (borders or fonts, for example) and any conditional formatting rules that you have defined in TableView are restored when you reopen the session file or report template; only the values will be updated from the linked CSV file. Using overlay areas in report templates allow the user to overlay multiple times and append rows/columns in which the cells are formatted according to the same rules used at the first import.



PowerPoint Publishing (Windows Only)

On Windows, two more options to define the picture resolution have been added. Using the newly-added scale factor to the PPT Presentation resolution, which was the default in 14.0.110, makes it easy to control the proportion of text/labels in axes and legends in relation to the images in the PowerPoint presentation.

Using the Fixed Resolution allows the user to define either the image height or width and the aspect ratio of the PPT master template. The PPT Publishing ensures that, for syncing, the image dimensions will be the same in PPT as long as the user uses the same settings saved by HWD at the time of the initial export.

The HyperWorks Desktop area resolution captures the images as they are displayed on the screen and fits them proportionally into the PowerPoint window with the first export, maintaining the aspect ratio.

Interfaces

• Support of NODOUTHF and ELOUTHF ASCII files from LS-DYNA

Resolved Issues

• The unit support for the HIC function in the VST Pedestrian Impact tool has been fixed; the values are no longer zero.



• For some NASTRAN-generated PCH files with line numbers, the imaginary values were wrong. This bug has been fixed.

• The filtering for horizontal or vertical axes in combination with the plot type has been improved.

• The page title will now only be updated the first time a curve is loaded via the Build Plots panel; in previous versions, changes made in the page title where overwritten.

• Line segments in Bar Chart lines are now displayed even when they are partly outside of the GUI.

• PPT Publishing offers new features to control both the font size of legends/labels and the aspect ratio of the exported images (see above for details).

• In PPT Publishing, broken links to images or text fields are again displayed in red when using the “View Names” feature in the ALTAIR PowerPoint plug-in. This feature was broken in previous versions.

• Reading SECFORC *DATABASE_CROSS_SECTION group results from LS-DYNA BINOUT files no longer show random numbers instead of the section name as requests in the Build Plots panel.

• Missing documentation for the Flexible Report APIs has been added.

• Copying and pasting pages or windows no longer changes the axis units for Dyna result files.



MotionView 14.0.120 Release Notes

Highlights

Non-linear Finite Elements

Version 14.0 introduced the experimental feature “NLFE Body” which enables you to model non-linearly flexible components in your multibody system. Version 14.0.120 marks the formal release of the NLFE.

A generic NLFE Body can be created using either the BEAM or CABLE element. The NLFE Body is based on the Absolute Nodal Coordinate Formulation (ANCF). Nonlinearity can occur for two main reasons: (A) Geometric nonlinearity and (B) Material non-linearity. The NLFE body supports both.

Refer to MotionView User Guide and MotionSolve Reference Guide for more details.

The NLFE features available in earlier version have certain improvements.

• MotionView now supports providing number of fibres information for Cable elements

• An additional set of constraints CONN0 are introduced by default at NLFE grids that are associated with markers to rigidify the grid. The constraints are of the form <CONN0 id = “conn_id” gid = “grid_id” conn = “TTTTTT” />. The statement constrains the gradient vector. First 3 keywords ‘T’ in the conn attribute represents constraint on the gradients along X, Y & Z direction while the remaining 3 ‘T’ represent constraint in the rotational (shear) direction. The form of these constraints can be changed using an environment variable HW_NLFE_CONN_TYPE = ssssss, where s can be either ‘T’ or ‘F’

Subsystems

Version 14.0 introduced “NLFE Subsystems” in an experimental form along with the NLFE body. The NLFE Subsystem contain tools to create an NLFE based stabilizer bar and helical spring. In this version, the toolbar “NLFE Subsystems” has been renamed as “Subsystems”. Along with NLFE, the experimental tag on the Subsystems is also removed. In addition, a belt pulley system creation tool is made available.

Belt Pulley System

A belt-pulley system can now be assembled quickly using the Belt-Pulley Subsystem tool available within the Subsystems toolbar

Two types of belt modeling methods are now available

1. NLFE – the belt is modeled as an NLFE Body

2. Discretized rigid bodies –the belt is approximated to a series of rigid bodies connected via spring-damper forces



Known limitations

• NLFE Belt pulley currently can only be used where the belt-pulley plane is parallel to the Global XZ plane

• Once the system is created, the belt modeling method cannot be toggled.

• Discretized rigid bodies Belt pulley system consists of a large set of entities. Creating or working with this system could be slower

Unit Support to Material Properties

MotionView now handles unit conversions automatically on Material Properties. The properties in the Materials dialog display the values in the Solver Units that are selected. Mass-inertia & CG properties of rigid bodies that get their properties from primitive graphics or CADGraphics and NLFE Body get updated automatically when units are changed.



Ellipsoid Graphics Support

It is now possible to define an ellipsoid graphics in MotionView that can be used with MotionSolve and Adams.

Resolved Issues

• An app error with the expression builder when an entry field contains improper function is fixed.

• An application crash associated with the usage of curly braces in the location function loc_along_dir has been fixed.

• An issue with resolving point for orientation of tire graphics has been resolved.

• Mass-Inertia of CADGraphics (and thereby their parent body mass-inertia) were not being updated immediately when property of materials referenced by CADGraphics were changed. This issue has been fixed.

• An issue with components of inactive File Graphics not being read when they are activated is resolved.

• While importing CAD, MotionView now uses the underscore (_) that might exist in the component names while assigning a varname.

• An issue with the macro “Export MDL” in HyperMesh to generate an h3d has been resolved.

• A regression in v14.0.110 in the 3D Cartesian Curve where the curve was being displayed by default in the Global Frame has been resolved.

• An issue with CG inertia summary where the dialog closes when using the Return key after an entry has been fixed.

• A crash while assigning material to a system attachment is resolved.

• The MNF to H3D conversion in flexprep has been enhanced to calculate inertia invariants for MotionSolve. MotionView will now show FEM Inertia Properites for the flexible body with the newly converted h3d from mnf.



• A minor enhancement to the Assembly Wizard GUI now provides the ability to skip the Attachment Wizard after selection of systems.

The new graphic shows the master and slave parts connected through a dotted line drown with the color of the master. Moreover in the Solver Browser a specialized review is also provided.

From the Solver Browser the user also has access to a new CRB Hierarchy tool. To access the tool, right click on the constrained rigid bodies folder.

CRB Hierarchy browser lists all the constrained rigid bodies available in the model, with information over its master and all its slave parts. The tool will show all the slave parts associated to the same master rigid under a single entity.

In addition all the rigid parts that are not linked to constrained rigid bodies entity are also listed in the CRB Hierarchy tool to facilitate the creation and\or modification of such such entity. The CRB entity can be modified through drag and drop of parts in such browser.

Right click on an existing constrained rigid body entity to add a rigid part from the master component.



A new constrained rigid body can be created by dragging the component(s) design as slave onto the component that will become the master of the newly created constrained rigid body.

Removing a slave part(s) from a constrained rigid body is also possible by selecting the slave part(s) and clicking on remove. You can also right click on the master part and remove all its slave part(s) from such constrained rigid body.
