Fluent FSI Error : Unassigned interface zone detected for interface 6.


If you're trying to perform a FSI simulation using Ansys Fluent & Mechanical and getting the following error when you click on "Check Mesh" :

WARNING: Unassigned interface zone detected for interface 6.

WARNING: Mesh check failed.

To get more detailed information about the mesh check failure
increase the mesh check verbosity via the TUI command
/mesh/check-verbosity.

The reason of the above error is that type of BC which is set for your FSI interface is set to "Interface" while it should be "Wall" with an applied dynamic mesh on it...
