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. |

Hi wind6, I have the same message, namely:
Code:
+-----------------------------------------------------------------------------+ | Warnings were found during data model validation. | +-----------------------------------------------------------------------------+ | Warning: Participant Fluid Flow (Fluent with Fluent Meshing) | | (CouplingParticipant:Solution 1) has the ExecutionControl 'Option' set | | to 'ExternallyManaged'. System Coupling will not control the | | startup/shutdown behavior of this participant. | | Warning: Participant Thermal-Electric (CouplingParticipant:Solution) has | | the ExecutionControl 'Option' set to 'ExternallyManaged'. System | | Coupling will not control the startup/shutdown behavior of this | | participant. | +-----------------------------------------------------------------------------+ Did you by any chance happen to solve the issue? |

Check if the static simulation runs on its own. Make sure the time step in static and fluids side is the same. Well it system coupling should override the time step anyways. But yea, make sure your simulation runs on its own first.
