System coupling problem
 

Hello All,
I am doing a 2FSI simulation using system coupling.

But after the solvers are connected I get the following error -

"The FSI interface names of the mechanical are different from the participant region names of the system coupling."

I rechecked many times and also resetup once more, but I still get the same error.

PS- I did the setup on Windows, but running it on linux cluster. If I run it on my windows machine I don't any error.
But I need to run it on a linux cluster, and I can't setup on the linux cluster. I can only submit jobs.

Thanks
