Hi everyone！ After completing a two-way fluid-structure interaction simulation in Ansys and importing the results into Ensight, I noticed that the data is divided into three cases: fluid, structure, and system coupling. However, only the stress on the structure changes over time. There is no deformation or displacement observed, and I also don't see any interactions between the fluid and the structure. Could anyone kindly help me understand why this might be happening? Thank you very much for your guidance!

Check this tutorial Reed Valve FSI Co-Simulation with Partial Setup Export from Workbench (Fluent-Mechanical) to validate that your setup is correct. There is also a section on Post-Processing in EnSight.

My understanding is that the results need to be processed after Case 1 (System Coupling) is completed. However, how can I view the pressure or velocity contours for the computational domain in this case?

If I have three cases to compare, how should I set up Sync?
Should I use case linking?
Please help me!!
