Hi, I am really new to Fluent. I am working on a FSI modelling by coupling transient structural and Fluent. An error came out, shown as below:
System Coupling Co-Simulation Summary |
+================================================= ===================+

Participant : Solution 2
Version/Build Info = 14.5.0
Participant : Mechanical APDL (Solution)
Version/Build Info = Mechanical APDL Release 14.5 UP20120918
WINDOWS x64 Version


+================================================= ===================+
| NOTICE |
| An exception has occurred and has been transmitted to the coupling |
| participants. These participants have been disconnected from the |
| coupling service. |
+================================================= ===================+



+================================================= ===================+
| System Coupling Exception |
+================================================= ===================+
| Origin : Copy of Fluid Flow (Fluent) (Solution 2) |
| Error Code : 20 |
| Error Description : |
| Exception encountered when the coupling service requested |
| ChartableData->GetRootLevelName: Communication socket |
| unexpectedly disconnected. |
+================================================= ===================+


System coupling run completed with errors.

It seems that system coupling process worked only on Sructural while not on Fluent. Could anyone help me with this error?

I think this error occurs when Fluent and MAPDL both try to get the same license. If you are using an Academic License then you'll need to turn off license sharing in your Workbench license preferences.

Hi Stumpy, The error is gone after I turned off license sharing. Thank you so much~~
