CAD Import/Export

In order to support all options available in the CAD reader/writer .ini files to also be defined within Tcl scripts, new CAD import and export commands *geomimport and *geomimport have been created.

These commands replace all usage of existing commands, though the older commands can still be used.

  • *geomimport replaces the use of *feinputwithdata2. This older command may still be used, however none of the new options supported with *geomimport are available. Only the options that were previously supported may be used.
  • *geomexport replaces and deprecates the use of *geomoutputdata2 and *iges_write_units. These older commands may still be used, however none of the new options supported with *geomexport are available. Only the options that were previously supported may be used. In addition, they will write out the new *geomexport command syntax to the command file.

Groups to Constrained Rigid Bodies

The LS-DYNA keyword *CONSTRAINED_RIGID_BODIES has been mapped from the group entity to the newly added constrainedrigidbodies entity. See the constrainedrigidbodies Data Names documentation for more details.

Scripts that created or queried the group entity for these keywords must be updated to use the constrainedrigidbodies entity. Below are a few examples.

To create a *CONSTRAINED_RIGID_BODIES keyword, assign a main rigid part ID, and 2 secondary rigid part IDs:
*createentity constrainedrigidbodies config=101 mastercompid=$comp_id slavecompids={comps $comp_id1 $comp_id2}

Encryption

Accessing data of encrypted entities using HyperMesh Tcl Query Command commands is blocked (returns 0). There are exceptions for some common data names and commands as follows:
  • hm_getvalue - Query allowed for color, definedentity, encrypted, id, include, includeid and name.
  • hm_getentityvalue - Query allowed for color, id, include and name.
In addition, updating data of encrypted entities using HyperMesh Tcl Modify Command Tcl commands is blocked. There are exceptions for some common data names and commands as follows:
  • *setvalue - Editing allowed for color, definedentity, id, include, includeid and name.
