Model

Model commands are used to create Abaqus/CAE models. A finished model contains all the data that Abaqus/CAE needs to create and submit an analysis to Abaqus/Standard or Abaqus/Explicit. Models are stored in a model database.

Other Classes

class KeywordBlock[source]

Bases: object

The KeywordBlock object contains a representation of its model in the Abaqus input file format. You may edit the contents of the KeywordBlock to add solver functionality that is not supported by Abaqus/CAE. As a general rule, edits to the KeywordBlock object should be made as the last step prior to writing the actual Abaqus input file, thus avoiding possible conflicts with changes made using other MDB commands. The KeywordBlock object has no constructor. A KeywordBlock object is created when you create a model object. A model object contains only one KeywordBlock object.

Note

This object can be accessed by:

mdb.models[name].keywordBlock

Parameters:
edited=0

A Boolean specifying whether this objects sieBlocks member has been edited. Setting edited=False will set the sieBlocks member to an empty tuple, thereby discarding all previous edits.

sieBlocks : --is-rst--:py:class:`tuple`\ \[:py:class:`str`, :py:data:`...<Ellipsis>`] = ()[source]

A tuple of Strings specifying a sequence of Strings that is identical to the information written to the Abaqus input file. Each String in the sequence represents an Abaqus input file keyword along with the parameters and data lines associated with the keyword. A String can also be a comment in the input file. You initialize this data member by calling synchVersions. After you initialize the data member, you use calls to replace and insert to record your edits in the correct location. If the last call to synchVersions used the argument storeNodesAndElements = False, the entry for the keywords NODE and ELEMENT will contain only the keyword and its parameters, not the data lines.

synchVersions(storeNodesAndElements)[source]

This method synchronizes, or merges, the edits made in this object with those made in the model using other scripting commands or the user interface. The synchVersions method updates the sieBlocks member. The sieBlocks member is empty prior to the first call to synchVersions. As a side effect, synchVersions sets lastSynchCount to the current value of the counter associated with the Mdb object, which is used to determine if synchronization is necessary.

Note

Check KeywordBlock.synchVersions on help.3ds.com/2024.

Parameters:
storeNodesAndElements

A Boolean specifying whether the nodal coordinates and element connectivities (i.e. the data lines for the NODE and *ELEMENT keyword blocks) are to be stored in the **sieBlocks* member. All other keywords and their data lines are always stored. The default value is True. If storeNodesAndElements is True, the size of the keywordBlock data will be similar to that of the input file. Since the KeywordBlock is stored in the Abaqus/CAE database, this will result in a larger database. It will also result in a slower execution of the synchVersions command. If storeNodesAndElements is False, the data lines are not stored in sieBlocks. Consequently, only set storeNodesAndElements = True if you wish to make changes to the NODE or ELEMENT data lines themselves. If your task is limited to reading nodal coordinates and element connectivities (i.e. not editing this information) then it is generally better to access this information from other parts of the Mdb.

Raises:

This method creates a Model object by reading the keywords in a Nastran bulk data file or Nastran input file and creating any corresponding Abaqus/CAE objects. The default values is discussed in following and can be defined alternatively in the Abaqus environment file as the one used for the translator from Nastran to Abaqus. For more information, see Translating Nastran data to Abaqus files.

Note

sectionConsolidation=PRESERVE_SECTION

A SymbolicConstant specifying the method used to create shell section. Possible values are PRESERVE_SECTION, GROUP_BY_MATERIAL, and NONE.

If GROUP_BY_MATERIAL is used, a single Abaqus section is created for all homogeneous elements referencing the same material. In both cases, material orientations and offsets are created using discrete fields. If NONE is used, a separate shell section is created for each combination of orientation, material offset, and/or thickness. The default is PRESERVE_SECTION.

A Boolean specifying whether to translate the beam element connectivity to newly created nodes at the offset location and rigidly coupling the new and original nodes. If not, beam element offsets are translated to the CENTROID and SHEAR CENTER options, which are suboptions of the BEAM GENERAL SECTION option. The default value is ON. When the beam element references a PBARL or PBEAML property or if the beam offset has a significant component in the direction of the beam axis, the setting for this argument is always ON.

cbar=B31

A String specifying the 2-node beam that is created from CBAR and CBEAM elements. Possible values are B31 and B33. The default is B31.

cquad4=S4
