How to define ABAQUS keywords in ANSA ANSA v13.x.x

GENERAL REMARKS

1. How to determine parameters of keywords specified with names.

Generally in ANSA, the names of such parameters can be specified through the ‘Name’ field of all cards that the names have meaning.

For instance, the name of NAME parameter of *AMPLITUDE keyword can be specified through the ‘NAME’ field as shown in the figure at the left side.

Then, the result that is taken during output (in *.inp file):

*AMPLITUDE, NAME=TIME_MAGNITUDE, DEFINITION=TABULAR, SMOOTH=.25, VALUE=RELATIVE, TIME=STEP TIME

.0, .0, 1, 1.

In order that the ID of the specified entity is needed to be written in the name, activate the ‘Preserve Ids in Names’ flag of “ABAQUS Output Parameters” window during output. The general format of the name in such a case will be: NAME= (default prefix)(ID);(name).

The prefixes of the keywords that ANSA supports are listed in ANSA.defaults file:

# ABAQUS names' prefix library# Leave lines in comments, for ANSA to assign default prefixes.## Abaqus.NamePrefix AMPLITUDE = A# Abaqus.NamePrefix BEAM_SECTION = P

BETA CAE Systems S.A. 1


# Abaqus.NamePrefix COHESIVE_SECTION = P# Abaqus.NamePrefix CONNECTOR BEHAVIOR = M# Abaqus.NamePrefix CONNECTOR_DERIVED_COMPONENT = D# Abaqus.NamePrefix CONNECTOR_DERIVED_COMPONENT (MatDB) = D# Abaqus.NamePrefix CONNECTOR_SECTION = P# Abaqus.NamePrefix CONTACT_CLEARANCE = CL# Abaqus.NamePrefix CONTACT_PAIR = T# Abaqus.NamePrefix CONTINUUM_SHELL_SECTION = P# Abaqus.NamePrefix COUPLING = C# Abaqus.NamePrefix CUTTING_SURFACE = C# Abaqus.NamePrefix DASHPOT_PROP = P# Abaqus.NamePrefix FASTENER_PROPERTY = P# Abaqus.NamePrefix FILTER = F# Abaqus.NamePrefix FLUID BEHAVIOR = M# Abaqus.NamePrefix FLUID CAVITY = FC# Abaqus.NamePrefix FLUID EXCHANGE = FE# Abaqus.NamePrefix FLUID EXCHANGE ACTIVATION = # Abaqus.NamePrefix FLUID EXCHANGE PROPERTY = FEP# Abaqus.NamePrefix FLUID INFLATOR = FI# Abaqus.NamePrefix FLUID INFLATOR PROPERTY = FEP# Abaqus.NamePrefix GAP_PROP = P# Abaqus.NamePrefix GASKET BEHAVIOR = M# Abaqus.NamePrefix GASKET_SECTION = P# Abaqus.NamePrefix INTERACTION_OUTPUT = I# Abaqus.NamePrefix JOINT_PROP = P# Abaqus.NamePrefix LOAD CASE = # Abaqus.NamePrefix MATERIAL = M# Abaqus.NamePrefix ORIENTATION_C = O# Abaqus.NamePrefix ORIENTATION_NODES_C = O# Abaqus.NamePrefix ORIENTATION_NODES_DYN = O# Abaqus.NamePrefix ORIENTATION_NODES_R = O# Abaqus.NamePrefix ORIENTATION_NODES_S = O# Abaqus.NamePrefix ORIENTATION_R = O# Abaqus.NamePrefix ORIENTATION_S = O# Abaqus.NamePrefix SECTION_CONTROL = C# Abaqus.NamePrefix SET = # Abaqus.NamePrefix SHELL_SECTION = P# Abaqus.NamePrefix SOLID_SECTION = P# Abaqus.NamePrefix SPRING_PROP = P# Abaqus.NamePrefix STEP = # Abaqus.NamePrefix SURFACE = S# Abaqus.NamePrefix SURFACE_INTERACTION = I# Abaqus.NamePrefix SURFACE_SECTION = P# Abaqus.NamePrefix TRUSS_PROP = P

Thus for the above example, the NAME of *AMPLITUDE will have the following format during output:

*AMPLITUDE, NAME=A1;TIME_MAGNITUDE, DEFINITION=TABULAR, SMOOTH=.25, VALUE=RELATIVE, TIME=STEP TIME.0, .0, 1., 1.

The user is able to give own prefixes if un-comment the desired Abaqus.NamePrefixes (remove the # symbol at the start of the line) and type any name after equal symbol of each Abaqus.NamePrefix (up to four characters can be specified). In example:

# ABAQUS names' prefix library# Leave lines in comments, for ANSA to assign default prefixes.Abaqus.NamePrefix AMPLITUDE = TIMG.

In this case, the name of NAME parameter will have the following format during output (have in mind that ‘Preserve Ids in Names’ flag of “ABAQUS Output Parameters” window should be active):



*AMPLITUDE, NAME=TIMG1;TIME_MAGNITUDE, DEFINITION=TABULAR, SMOOTH=.25, VALUE=RELATIVE, TIME=STEP TIME.0, .0, 1., 1.

In cases it is not desired to assign prefixes in some entities, uncomment and leave them blank.In example:

# ABAQUS names' prefix library# Leave lines in comments, for ANSA to assign default prefixes.Abaqus.NamePrefix AMPLITUDE = Abaqus.NamePrefix BEAM_SECTION =

Then during output:

*AMPLITUDE, NAME=(just the name specified in the card)*BEAM SECTION, ELSET=(just the name specified in the beam section card).

NOTES:

ANSA should be reopened so as to read any change in ANSA.defaults file.

In case there are prefixes defined in more than one ANSA.defaults file (ANSA_HOME, HOME or Current directory) in order to avoid overwriting the prefixes the user can un-comment the “Abaqus.NamePrefix Lock_current_state = true” line (just after the prefixes) in order to guide ANSA to not alter the already read prefixes in case other prefixes will be read from other ANSA.defaults file(s).

The status of 'Preserve Ids in Names' flag of ABAQUS Output Parameters window (File>Output>ABAQUS) can be controlled by the folllowing line of ANSA.defaults file:

Abaqus.Preserve IDs in Names = YES



2. Defining non-linear material properties (as a function of temperature) in tabular forms.

The non-linear material properties can be defined almost with the same way for all material properties inside ANSA. The steps that should be followed are:

2.1 Set ‘DEP’ pull down menu of each material property to YES. In example, set DEP option of *DENSITY to YES as shown in the figure at the right side.

2.2 Press the ‘?’ key in ‘DATA TABLE’ field that appears.

2.3 Create a new table by pressing the corresponding button (NEW>DATA TABLE) in “DATA TABLE HELP” card that opens.

2.4 Specify the values in i-columns and j-rows (as many as needed) and press OK to declare the definition. For *DENSITY option two columns are needed. The values in the first column are considered as the density values and in the second column the temperature values.

2.5 Double click on it to appear its ID in ‘DATA TABLE’ field.

? 2


NOTES:

Each row implies one data line during output.

The values of each property are specified in each column. The temperature values are always specified in the last column of the table.

3. Fix operations for pyramid elements created inside ANSA.

The volume meshing can be implemented by using any function (mainly any algorithm of MESHV) located in VOLUMEs group of MESH menu. In many cases, when quads exist in the surface mesh of the volume pyramid elements are automatically generated during volume meshing. The created pyramids can be fixed either by using CHECK>PYARAMIDS function (ABAQUS deck) or by activating the ‘Split Pyramid in Tetras’ flag during output (“ABAQUS Output Parameters” window).

3.1 The PYRAMIDS check.

Activating this function (D.UTIL menu) all detected pyramid elements in the visible model appear as errors (coloured in red) in “Checks” list that opens.

Select ‘Fix’ option in the pull down menu that appears, when pressing the right mouse button on it, to split pyramids into tetras.


CHECK

------------------

PYRAMIDS


The result is also displayed on the screen.

3.2 The ‘Split Pyramid in Tetras’ flag.

Activating this flag the identified pyramids according to the mode of the Output (All/Model/Visible) are automatically split into tetras during output.

A relative warning message is also reported in the TEXT widow whether pyramids are detected in the model during output.

The result is presented in the current input file (*.inp).

4. Usage of ANSA tooltips and function finder for any ABAQUS keyword and subsequent parameters identification.



4.1 Tooltips

The tooltips are very useful in order to understand which is the usage of the fields and menus inside a card. For instance the card in the right figure shows all parameters concerning the *BOUNDARY keyword. If putting the mouse cursor upon a field or menu, detailed information will appear. The information is written in the same manner as in ABAQUS keywords reference manual and so the user is not needed to switch to ABAQUS manual. In this case if putting the cursor on OP menu, all details of OP parameter are introduced. Thus, tooltips are useful to identify easily and fast the keywords and subsequent parameters.

4.2 Function Finder

In each of the following supported keywords, they are described all possible ways to create the keyword. Due to the fact that the user may be not familiar with ANSA interface, the Function Finder can be used in order to activate a function. In example, the user wants to define the *AMPLITUDE keyword. If going to the Created by section of this keyword, there is one main way to define it and this is through AUXILIARIES>AMPLTD function. Since it requires more time to find the function in ANSA interface it is better to press Ctrl+F keys (default short-cut) or MENUBAR>Windows>Function Finder to open Function Finder window, then write the function (as shown in the figure) and finally Enter to activate it.



5. Orientation of Surfaces

All “orientable” elements (e.g. Shell, Gasket, Continuum Shell, etc) and the respective Properties contained in SETs, can be given a particular Orientation (SPOS / SNEG). This is a characteristic of the Set and can be assigned per contained entity, i.e a Shell property defined as Oriented= SPOS in one Set can be Oriented=SNEG in a different Set. Also two Properties in a Set can have different Orientation.

The orientation of the exported surface, based on the Set (Output as surface), is specified either by the “ORIENTATION” type or by the Entity's Orientation that is now available.

In order to define the orientation on a set's contained entity:

- Open the SET management window and click on Set's contents that need to specify Orientation.

- The Database Browser List with these entities (e.g. Properties) appear with the Column “Oriented”. This appears as an option within the Entity's card as well. However, the field/column becomes available only through the Set management.

- Using Quick Modify you can change the field directly in the list.



- The Entities assigned orientation are listed under the ORIENTED section

4. Activate the ‘Output element’s thickness’ flag in conjunction with ‘- as DISTRIBUTION’ option through “ABAQUS Output Parameters” card during output.



B) The most simple way to define the *DISTRIBUTION keyword for orientation:


2. Select existing shell elements from the screen which are referenced by composite or laminate properties, right click on highlighted items in “Selection” list and use Modify option.

3. Switch 'mat.orient' option either to ANGLE and specify a value in ANGLE field or to mcid and press '?' or 'F1' keys in mcid field to select an existing coordinate system from the list and screen respectively (SHELL ELEMENT CARD).

C) The most simple way to define the *DISTRIBUTION keyword for shell offsets:


5. Select existing shell elements from the screen which are referenced by shell properties, right click on highlighted items in “Selection” list and use Modify option.

6. Specify a value in ZOFFS field (SHELL ELEMENT CARD).

Remarks The element sets names are supported only during input.

Only LOCATION=ELEMENT and TYPE=SCALAR are supported by ANSA. The NAME parameter obtains always the standard name DISTRIBUTION_ THICKNESS for case A) and DISTRIBUTION_MAT_ORIENTATION for case B) as well as the TABLE parameter the name TABLE_THICKNESS for case A) and TABLE_MAT_ORIENTATION for case B) and cannot be determined by the user.

Angles throughout the (90, -90) range are supported only when 'Output Format' option is switched to 6.8 or 6.9 (ABAQUS Output Parameters window).

Especially in case B) angles and coordinates are supported. So, ANSA creates automatically an:

*ORIENTATION, DEFINITION=OFFSET TO NODES

1,2,3

3, (the name of *DISTRIBUTION which are listed the angles of each shell).

*DISTRIBUTION with coordinates (*DISTRIBUTION TABLE with COORD3D) is supported only during input. In output the coordinates are converted to respective angles (*DISTRIBUTION with angles are written out).

This orientation is defined in the respective shell composite property.

*DISTRIBUTION with thickness and orientation is supported also in layers of *SHELL SECTION, COMPOSITE property. This way, variable thicknesses and orientations on each composite layer can be given. Use AUXILIARIES>LAMINATE>by LAYER NAME to merge layers with different thicknesses and angles. The active 'mapped data' status indicates that the values of current layer are variable so *DISTRIBUTION keywords will be exported for these types.

For an ABAQUS/Explicit analysis, the keyword can be output provided that the 'Output Format'



option is switched to 6.7 6.8, or 6.9 (ABAQUS Output Parameters window).

Keyword *DISTRIBUTION TABLE

Created by 1) Automatically by following the A) case of *DISTRIBUTION keyword in order to define shell thickness (LENGTH).

2) Automatically by following the B) case of *DISTRIBUTION keyword in order to define orientation (only type ANGLE).

3) Automatically by following the C) case of *DISTRIBUTION keyword in order to define shell offsets (RATIO).

Remarks See Remarks of *DISTRIBUTION keyword related to the way of NAME parameter determination.

For sets the option 'Output as:” should be switched to Set in order to output *DLOAD keyword.

Since CPE, CPS,CAX, DC2D and DCC2D4 are solid element types but in ANSA they are faced as shells, use Element or Set of elements options to select “big” facets and Edge or Set of edges options to select other facets (“thickness” facets). For solid types C3D, DC3D, DCC3D and AC3D when using LOADs>DLOAD>P/PNU/HP or/and VP >Set the set should contain solid facets and whole solids for all other functions (GRAV, VBF and CENTRIF options) in order to be valid .

Keyword *VARIABLE MASS SCALING

Created by Using AUXILIARIES>STEP>NEW, switching to *VARIABLE MASS SCALING ‘Keyword’ and pressing the INSERT button to declare the definition.

Remarks The ELSET parameter obtains the same name with name of the set that is used. The user is able to select more than one sets at once in order to define more than one output requests quickly. See also GENERAL REMARKS how to determine the name of ELSET parameter.

Select DYNAMIC, EXPLICIT ‘ANALYSIS’ because *VARIABLE MASS SCALING makes sense only in an Abaqus/Explicit analysis.

Keyword *VISCO

Created by Using AUXILIARIES>STEP>NEW and then selecting the *VISCO option into the pull down menu of ‘ANALYSIS’ section.

Remarks Left-click on the 'Parameters' button to specify the parameters as desired.


Keyword *VISCOELASTIC

Created by Using MENUBAR>Windows>Materials>NEW>MATERIAL and switching the ‘*VISCOELASTIC’ option to YES.

Remarks Set ‘DEFINED’ option to YES (located at the top of “MATERIAL [MATERIAL]” card) so as the specific *HYPERELASTIC option to be written to the output file (.inp).



In options where 'DATA' field appears, specify the data lines in tabular form (press ? key in 'DATA' field and “DATA TABLE” window will appear to specify data values in rows and columns, each row corresponds to one data line).

Keyword *VISCOUS

Created byUsing MENUBAR>Windows>Materials>NEW>MATERIAL, switching to VISCOUS ‘Plasticity (Rate Dep.)’ and setting ‘*VISCOUSP’ option to YES.

Remarks Set ‘DEFINED’ option to YES (located at the top of “MATERIAL [MATERIAL]” card) so as the specific *VISCOUS option to be written to the output file (.inp).

The temperature values may be specified only if ‘DEP_VSC’ option is set to YES.
