User Experience• Parametric Expressions in Coordinates D1068, D1118, D2321, D4064, D4266, D4438, D5022

◦ Produce powerful parametrically driven simulations▪ Improves simulation automation and template capabilities▪ Reduces need for Java scripts▪ Broadens scope of fields available for optimization studies in Design Manager▪ Increase simulation robustness with less opportunity for input errors: a single parameter controls

multiple inputs◦ Define any Coordinate input field using Scalar and Vector Global Parameters



◦ Expressions in Coordinates can only be defined from Scalar and Vector Global Parameters: there is nosupport for expressions defined with non-spatially varying Field Functions, such as report values

◦ Coordinate field examples (non-exhaustive list):▪ 3D-CAD > Body:

- Transform > Translate: Translation Vector- Transform > Rotate: Axis Position & Direction- Linear Patterns: Axis Directions

▪ Geometry > Operations:- Transform > Translate: Translation Vector- Surface Extruder: Direction

▪ Derived Part:- Point Probe: Point- Line Probe: Point 1 & 2- Plane Section: Origin & Normal

▪ DFBI > 6-DOF Bodies > Initial Values > Body > Center of Mass▪ Tools:

- Coordinate Systems > Local Coordinate System: Origin (not Axis Directions)- Transforms > Simple Transform: Rotation Origin, Axis, Translation



• File Parameters D1613◦ Reduces Java scripts and increases simulation automation◦ A new File Parameter Type can be created under Tools >

Parameters, complementing Scalar and Vector Parameter Types▪ To specify the File Parameter value, enter the path directly, or

use the File Browser provided▪ In this release, File Parameter is available in the Replace Part Mesh Operation, including support in

Design Manager- Additional information can be found in the Design Manager section

List View mode▪ The Name criterion, using the 'Starts with' or 'Contain' conditions, is clearer to apply when Inherited

Parts are involved



• Automatic Resizing of Text Field in Predicate◦ Save time building queries

▪ Less clicks adjusting window size to enter text value◦ The text fields in predicates are now resized automatically as a function of the window size. Valid in:

▪ Query Editor▪ Repair Surface: Search Filters pane

• Search the Simulation Tree D4720◦ Get to the right object, faster

▪ Reduces time traversing the tree, reduces mouse clicks and mouse miles when searching for anobject

◦ The common keyboard shortcut for search, Ctrl+F, now opens a new Search panel next to thesimulation tree.

◦ In the Search box:1. Type the text to find.2. Within search results, which are presented either as a tree or a list view, highlight objects of interest.3. To locate and edit objects directly in the tree, right-click an object and choose Select in Application.

◦ ▪ Multiple search results of the same object type can be selected at once, and edited at once, withSelect in Application



◦ The search experience is based on the filters framework:▪ The search pane has identical interaction modes as for filters both in the search results section and

in the advanced search section▪ The advanced search exposes the suite of predicates already available when building queries in

filters and query-based selections▪ A right-click in the advanced search mode allows you to save the search as a filter for later use



◦ Additional considerations, related to the use of the search engine in the Filter framework:▪ The items that can be found by name search are named objects (for example: parts, regions,

reports, parameters, and other objects which you can rename) and the field functions (both systemand user field functions)- Objects that cannot be renamed cannot be found by name search (for example: Physics Models)

▪ Some objects that are not visible in the main tree may appear in search results. This is a knownlimitation. When using Select in Application on such search results, no object is selected in thetree

▪ Triggering the Search from any special mode, such as 3D-CAD or Surface Repair, searches thewhole simulation tree, and Select in Application takes you out of the tool and back into thesimulation tree, without closing the tool

performing, customized interactive experience▪ Ensure local resources are utilized effectively▪ Tune your rendering performance on a case-by-

case basis◦ Volume Rendering Quality settings lets you trade off

between interactive performance and immersive quality▪ Immersive performance depends on your Scene content and hardware resources

◦ Precise Volume Clipping resolves the jagged appearance of clip planes intersecting boundaries▪ Better quality is achieved at a performance cost▪ For larger, more complex cases, leaving Precise Volume Clipping off may be practical

◦ Customize your immersive experience by selecting your own Ceiling and Floor textures▪ Controls are provided for content and scaling



• Enhancements to .avi Movie Export D2200◦ Improved quality for all direct movie exports to the

standard .avi format▪ Overcome video compression artifacts with choice

of quality- Options let you choose between High, Balanced,

or Low quality to trade off against file size◦ Animation creation is more robust with reset buttons to

recover settings for▪ Frame Rate▪ Start Time▪ Animation Length



• Display of errors in Monitor Plots◦ Increased confidence in results with improved visibility

on computation errors▪ Interactive runs show errors when they occur▪ Monitor plots have a state history for batch runs for

subsequent review◦ New expert property turns on the display of errors

▪ Error data points are visually differentiated, shownas an unfilled circle (color can be modified)

▪ Plot legend shows report monitor and error datapoints as separate series

• Cotemporal Reporting for Statistical Monitor Reports◦ Broaden your ability to effectively communicate your

results◦ Save time by getting more information from your existing reports◦ Values for any Monitors can be returned for the stored state (Iteration or Time Step) held by Statistical

Minimum/Maximum reports◦ Monitor collection policy can be set to All or Last N samples (consistent with Statistical Monitor Reports)

▪ Use a Monitor Waypoint to control sample collection clear & restart actions
