Hello everyone iam trying to create two way FSI static structural and CFX coupling(steady state) analysis. I took the example file(R37) from CFX as my reference to set boundary conditions. When i start the solution process it runs till 21 iterations and suddeny shows the following error.
Can someone please help me on this error.
