This section addresses issues that may occur in products that integrate with RSM.

CFD-Post Errors

If a project schematic contains CFD-Post, submitting a project or design point update to a Linux cluster via RSM may result in errors, and the update of the CFD-Post results cell may fail completely.

When launching CFD-Post on a remote Linux machine, the DISPLAY variable must be either unset or set to a valid X display before running in batch mode. For more information, see Running in Batch Mode in the CFD-Post User's Guide.

Explicit Dynamics Systems: No Linux Support

RSM does not support Linux connections for Explicit Dynamics systems. Only Windows-to-Windows connections are currently supported.

Workbench/Mechanical: Unexpected Behavior with Rigid Dynamics or Explicit Dynamics

If you are running Ansys Workbench on a multi-user RSM machine, the My Computer, Background option that is available for Ansys Mechanical (see Using Solve Process Settings in the Mechanical User's Guide) will likely not function as expected with Rigid Dynamics or Explicit Dynamics due to write permissions for RSM working directories. As a workaround for this issue, do not use the built-in ‘My Computer’ or ‘My Computer Background’ solve process settings.

System Coupling/CFX: CFX Solution Must be Set to Run in the Foreground

Coupled analyses (i.e., that have a System Coupling system on the project schematic) can be updated only in the foreground. All coupling participant setups must be consistent with that of System Coupling. Ensure that for each participant's Solution cell, the Solution Process | Update Option property is set to Run in Foreground.

To avoid this issue, ensure that any CFX coupling participant has its Solution | Update Option property set to Run in Foreground before submitting a coupling job to RSM.

Once an update has been attempted with a CFX participant’s Solution | Update Option property set to Run in Background, you may find that it is not possible to change the value of this setting for CFX. To address this issue, first reset System Coupling’s Solution cell and then set CFX to perform updates using Run in Foreground.
