solver error message
 

Good morning to everybody,
I have troubles with solver, I could see error message, which I've seen first time and I don't know, what does it mean. Does anybody have experience with this kind of error please?

thanks a lot

There is something wrong with a domain interface that uses a Mesh Connection = Automatic, or Direct.

It seems the mesh information for the faces on either side of such domain interface is corrupted. You can try workaround by setting the Mesh Connection = GGI.

If the workaround works, you may have to revisit the mesh details around such domain interface, and/or contact ANSYS support directly.
