Altair HWSolvers 2020.1.1 HotFix

The Altair HyperWorks development team has released an update to HyperWorks Solvers 2020 is a collection of finite element and multibody dynamics solvers for structural, fluid-dynamics and systems simulation.

Altair OptiStruct 2020.1.1 Release Notes

New Features
- PSDM output request for STRESS has been enhanced to include “Zero crossing” results (for von Mises) in Random Response Analysis. In addition to punch file, PSDM results including zero crossing are now available in h3d file under “PSD moments”.
- SPCOFF/SPCOFF1 has been added. These entries are used to specify degrees of freedom which should be excluded from AUTOSPC list.
Resolved Issues
- -cores auto had an issue with v2020.1 solver scripts and this is now fixed.
- A crash could occur for shell models in Sine Sweep Fatigue with surface stress option turned on. This has now been fixed.
- PARAM,ALLFT for composite failure output could produce the wrong results for certain failure criteria. This has now been fixed.
- MUMPS failure (-90) on Windows could occur for multi-threading case (-nt) in out-of-core mode. This issue has been fixed.
- Fatigue with Modal Transient could produce incorrect results if AMSES/AMLS are used and not all degrees of freedom are requested as output (that is for STRESS, DISP etc.). This has now been fixed.
- A programming error could occur for Thermal transient – Structure coupling when there are multiple CONTACTs. This has been fixed

Quenching Resolved Issues
Spray Quenching with Multiple Quench Zones
There was an issue for models with more than one spray quenching zone. Heat transfer was considered only in the first quench zone. This issue is resolved now.


HyperWorks Solvers is a collection of finite element and multibody dynamics solvers for structural, fluid-dynamics and systems simulation. These solvers can be employed for simulation driven design as well as design optimization.

The HyperWorks suite is solver independent so adopting the software does not require you to disregard your existing toolset. Instead HyperWorks can run alongside your incumbent solutions, adding value and saving research time and money when used.
