Nastran Interface 2020 Release Notes
Altair HyperMesh
New Features
- Element Addition
- Element type CQUADX4, CQUADX8, CTRAX3, CTRAX6 in Nastran NX profile
- New Material
- Material type MAT3 added in Nastran NX profile
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
