LS-DYNA Interface 2021.1 Release Notes

LS-DYNA Interface

New Features

Drive Mapping
On import of solver decks that contain includes, HyperWorks now allows mapping from one folder path to another to import include files where the include path written in the solver deck doesn’t match the location of the files. This includes different paths due to different operating systems. Found in Preferences > Drive Mapping, or in the Solver Deck import options, you can define the source path where the files reside, and the target path as written in the solver deck, and use this to successfully import files without the need to edit the include paths in a text editor.
Include Organization
The Organize context menu option is now available for all entities. The organization of entities into an include file has been improved to automatically consider all references linked to the selected entities.
New Reference Geometry Entities
The Reference Geometry entity provides a better support of the airbag reference geometry and foam reference geometry keywords. A dedicated graphical representation allows for the visualization of the airbag patches. The interactive modification of the nodes defining the *AIRBAG_SHELL_REFERENCE_GEOMETRY is also possible directly on the graphic.
New Load Entities
Some load and boundary keywords are migrated from the Load Collector entity to the dedicated Loads entity.

Enhancements

Creation of Curves
Efficiency improvement for creating/editing curves from any keyword entity editor by directly exposing the curve editor and accessing the curve X;Y data.
Mechanism in Assembly Ribbon
HyperWorks-specific. The Mechanism tool is now directly accessible from the Assembly ribbon, like any other solver interface supporting this tool.
New Keywords
*DEFINE_MATERIAL_HISTORIES, *MAT_ADD_INELASTICITY, *MAT_MODIFIED_PIECEWISE_LINEAR_PLASTICITY_PRESTRAIN
Updated Keywords
*DATABASE_EXTENT_INTFOR, *MAT_ADD_DAMAGE_DIEM, *MAT_ADD_EROSION, *MAT_ADD_PERMEABILITY, *INITIAL_STRESS_SECTION

Resolved Issues

  • Export issue in the third line of *DATABASE_CROSSSECTION_PLANE of type circle.
  • Transformations not applied on the correct include, when the include defined in *INCLUDE_TRANSFORM is not referenced in the model.
  • Export issue with field HISn of *MAT_ADD_GENERALIZED_DAMAGE.
  • Export issue in *DATABASE_OPTION when binary format is not specified.
  • Export issue in D2R line of *DEFORMABLE_TO_RIGID_AUTOMATIC.
  • Entity Editor limit is extended up to 100 for NVENT in *AIRBAG_PARTICLE.
  • IDROFF offset value in *INCLUDE_TRANSFORM will not apply on control cards anymore.
  • Addition of node and direction selection options to Vector entity creation.
