Rigid Controller

New options to automatically create Time History on RBODY and Independent Node have been added in the rigid controller for RBODY element creation.

Probelem for nested SUBMODELs in large models has been corrected.
HyperMesh files without composites data that was saved without attribute values for Plies would be exported with random values for those empty attributes. This export issue has been resolved.
HyperMesh files saved with version 2019 may have an issue exporting /GRNOD/NODE sets as empty /GRNOD/GENE sets. The export issue for such HyperMesh files has been fixed.
For /SKEW/MOV, an update has been made in keyword Entity Editor to have DIR attribute mapped to the previous Axis attribute.
For /TH/GAUGE, /GAUGE/SPH are now selectable.
