Enhancements

New Load Entities
OptiStruct loads (SPC, FORCE, PLOAD,….) are migrated to new HyperMesh entities. Along with this implementation, user can now create loads from solver browser and edit loads from entity editor. Some of the advantages with new load management are below:
  • Consolidation of loads by common attributes. For example, SID, Magnitude, etc.
  • Interrogation of loads are much powerful. For example, Review, Vector plot, Contour.
  • Advanced load option support:
    • Apply pressure on nodes
    • Apply traction on axisymmetric elements
    • Apply pressure on 1D elements based on element orientation
  • Solver Browser performance enhancements to handle large number of loads
New Set Segment Entity
Contact Surfaces entity is now migrated to the Set Segment entity. With this migration, the SURF/ELIST cards is now directly listed in the set segment entity.
Remove include file reference based on export status
HyperMesh only. When exporting a solver deck, references to any includes are always written to the master model even if the include itself is set to "Do Not Export."

Resolved Issues

  • HM freezes while importing a bdf with more than one Super Element
  • Incorrect Element System Visualization in Orientation Review
  • Incomplete SUPORT card export while creating gaps from linear gaps tool in Aero profile
  • Leading spaces in Case Control Section results in UNSUPPORTED cards on import
