Hi, I am trying to analyze 2-way FSI. In both static structural+steady fluent and transient structural+transient fluent, I have encountered same error:

"Update failed for the Solution component in system coupling. The coupled update for system Static Structural threw an exception. Error updating cell solution in System Static Structural."

Solution Information:

+-----------------------------------------------------------------------------+

| Warnings were found during data model validation. |

+-----------------------------------------------------------------------------+

| Restart output is only requested at last step. To enable restarts from |

| intermediate points, use another 'OutputControl' option. |

| Participant CouplingParticipant:Solution 1 has the ExecutionControl |

| 'Option' set to 'ExternallyManaged'. System Coupling will not control |

| the startup/shutdown behavior of this participant. |

| Participant CouplingParticipant:Solution has the ExecutionControl 'Option' |

| set to 'ExternallyManaged'. System Coupling will not control the |

| startup/shutdown behavior of this participant. |

+-----------------------------------------------------------------------------+



Awaiting connections from coupling participants...

+-----------------------------------------------------------------------------+

| "System coupling solution stopped before all participants connected. A |

| solver failure occurred during the run in the Static Structural system"


How to solve this problem?

Thank you.
