Hi everyone, i tried simulating to predict jetnoise farfield using FW-H model which is acoustic model, i had only 200,000 cells. I was able to simulate with Unsteady RANS model , the moment i switched to FW-H model, it barely ran 10 iterations, said signal recieved, then the fluent exited on its own. tried to check the fluent log but cannot understand what went wrong since i am a amateur user.
here is the error log Node 0 Fatal signal raised sig = Segmentation fault 8505c3a0 CX_Primitive_Error 272ab9d0 log2f 851024d0 logical_right_shift f004f6a0 _C_specific_handler 29eb4f20 _chkstk 29e2ddd0 RtlFindCharInUnicodeString 29eb4010 KiUserExceptionDispatcher 83c12b90 Compute_FWH_Var 83c12eb0 Extract_Acoustics_Signals 81ee9570 Check_Species_In_Thermodb 850ec470 eval 81f10150 PRF_Command_Start 81f12880 PRF_Node_repl 81f1e690 Delay_Error 851024d0 logical_right_shift 28442560 BaseThreadInitThunk 29e6af00 RtlUserThreadStart Node 0 Fatal signal raised sig = Segmentation fault 8505c3a0 CX_Primitive_Error 272ab9d0 log2f 851024d0 logical_right_shift f004f6a0 _C_specific_handler 29eb4f20 _chkstk 29e2ddd0 RtlFindCharInUnicodeString 29eb4010 KiUserExceptionDispatcher 83c12b90 Compute_FWH_Var 83c12eb0 Extract_Acoustics_Signals 81ee9570 Check_Species_In_Thermodb 850ec470 eval 81f10150 PRF_Command_Start 81f12880 PRF_Node_repl 81f1e690 Delay_Error 851024d0 logical_right_shift 28442560 BaseThreadInitThunk 29e6af00 RtlUserThreadStart Node 0 Fatal signal raised sig = Segmentation fault 8505c3a0 CX_Primitive_Error 272ab9d0 log2f 851024d0 logical_right_shift f004f6a0 _C_specific_handler 29eb4f20 _chkstk 29e2ddd0 RtlFindCharInUnicodeString 29eb4010 KiUserExceptionDispatcher 83c12b90 Compute_FWH_Var 83c12eb0 Extract_Acoustics_Signals 81ee9570 Check_Species_In_Thermodb 850ec470 eval 81f10150 PRF_Command_Start 81f12880 PRF_Node_repl 81f1e690 Delay_Error 851024d0 logical_right_shift 28442560 BaseThreadInitThunk 29e6af00 RtlUserThreadStart Node 0 Fatal signal raised sig = Segmentation fault 8505c3a0 CX_Primitive_Error 272ab9d0 log2f 851024d0 logical_right_shift f004f6a0 _C_specific_handler 29eb4f20 _chkstk 29e2ddd0 RtlFindCharInUnicodeString 29eb4010 KiUserExceptionDispatcher 83c12b90 Compute_FWH_Var 83c12eb0 Extract_Acoustics_Signals 81ee9570 Check_Species_In_Thermodb 850ec470 eval 81f10150 PRF_Command_Start 81f12880 PRF_Node_repl 81f1e690 Delay_Error 851024d0 logical_right_shift 28442560 BaseThreadInitThunk 29e6af00 RtlUserThreadStart I am not sure what is the error, Thanks in advance as i genuinely want to know if my modelling is wrong or it could be any other reason Last edited by Rena1; July 4, 2024 at 19:14.
