SubscriberI'm running ANSYS v221 on a Centos 8.3 system. When using a project created in ANSYS on Windows, Fluent used with System Coupling in Workbench returns the following error:
The mesh opens appropriately in the Fluent GUI and appears to be valid. Any suggestions for a fix?

Ansys EmployeeHi,
it is recommended that you build up to the final two-way analysis incrementally, progressively adding complexity with each step. Check if your participant solutions works fine with representative loads. Look at the transcript files for errors if any.
Please refer Building a Coupled FSI Analysis from Decoupled Participant Problems (ansys.com).

The workbench project I'm using runs fine on a windows desktop. The problems only occur when it's on Linux. What do you recommend?

Hi,
Have you tried running other system coupling projects on Linux? Is this error specific to this project?
is that file built in v221 in windows or previous version used for that?
Please try running tutorial Oscillating Plate FSI Co-Simulation with Partial Setup Export from Workbench (CFX-Mechanical) (ansys.com) on Linux.
