2-way system coupling error
Hi,
I'm trying to simulate a fluid-structure interaction with Fluent and Transient Structural. When I start solving the system coupling, the error message below appears:
Update failed for the Solution component in System Coupling. The coupling service failed to start.
Association: C3.
Can someone tell me where the problem is?
Thanks,

Hi, I am also getting same error while solving two way coupled fsi so please let us know what should do in this case.
Thank you

Hello,
How are you setting up your model? What are your Data Transfer? Have you attempted to start the Mechanical and Fluent simulations separately? Did you receive any error message when you run these simulations separately?
Thank you.

Hi Kremella, I have getting same error. I used both static structural+steady fluent and transient structural+transient fluent, but I have got same error. I have tried complete analysis in structural and fluent, they work.
Additionaly, I have got these explanations in soluion information:

Do u have any idea about that problem?
Thank you.

Hi @damladrms , @Abbu2u,
I recommend following these steps when encountering problems with System Coupling.
