I am interested to perform modal analysis of beam188 using fluid element around it in ANSYS APDL . I have created fluid29 elements near to beam element and provided FSI condition at beam -fluid interface nodes/line and performed analysis using " Unsymmetric" mode extraction method.The results from analysis differs from expected results. If anybody has suggestion on the analysis will be helpful.I have attached .cdb and .iges file for reference.
Thank you
