Dear All,
I am trying to do 2 way FSI and on coupling toolbar the message reads that the fluent encountered fatal error after sync point. I think may be the mesh is getting deformed so I need to do remeshing option but is not clear about it. I have attached the model picture for ready reference. I am using Transient Structural and Fluent with system coupling for the purpose, with SAS Turbulence model. The model has a pressure inlet and outlet and I am using rotating frame of reference for specifying the rotational velocity. Will UDF the better option for this?
Thanks in advance for any help.
