Prior to version 2021 R1 CFD Post can be used to view the FSI results (Both CFD and Mechanical). CFD Post does not support reading Mechanical 2021 R1 or later results files. Mechanical results could not be loaded in CFD-Post and while making connection from Mechanical solution cell to results (CFD-Post) it will throw an error.
Ensight supports viewing Combined System Coupling (FSI) results. Load the results of the coupling participants to Ensight ( Fluent/ CFX, Mecanical and SyC Results).
Please refer a postprocessing tutorial to know more about postprocessing in Ensight Postprocessing System Coupling's Co-Simulation Results (ansys.com).
