Hi.
I want to simulate a small structure in ANSYS and to consider fluid- structure interaction. I selected two way FSI. I done procedure for simulation FSI, but I faced with this error:

-Update failed for the Solution component in System Coupling. The coupled update for system Transient Structural threw an exception. Error updating cell Solution in system Transient Structural.

-(DP 0) System coupling run completed with errors. System Coupling Service reported: System coupling run aborted by user or due to fatal error. Please do not save the project if you would like to recover to the last saved state.

-(DP 0) A solver failure occurred during the run in the Transient Structural system

I don't know what should I do for resolving this error.
Thanks.
