trying to perform dynamic wall and FSI analysis together
 

Dear all,
I am trying to perform dynamic wall and FSI analysis together in this model.but it CFX can not solve and shows this message
ERROR #002100061 has occurred in subroutine SERVE_CLIENTS. |
| Message: |
| The connection between this CFX process and an external process |
| has died unexpectedly. The following error was received: |
| External process : ANSYS |
| Error experienced : Read |
| |
| ** This error is fatal: Terminating ANSYS CFX Solver execution ** |
| Please review the output, error and log files from both the CFX |
| and external processes to determine the cause of the error.

The Ansys solver crashed...

how to solve it？thanks！

Check the ansys error output file. This is the place to start.

but i had checked output files,and pasted it on the forum, i do not understand what is mean in this output file,can you help me? thanks

Where did you post it - to prevent double postings.
I can look at it but i am also more in CFD.. check the convergence for the Ansys part, check for "very" large deformations in one timestep, check the mesh movement.
