Specify inlet condition on overset patch
 

Hi

I am trying to specify a flow through an overset region in a simple block mesh (2D).
The purpose is to be able to swap e.g. an inlet geometry (overset mesh) which overlaps with a background mesh (e.g. a container). Thus, I am interested in specifying an inlet condition on one of the faces of the overset patch. Does anyone know how to do this?
I have done cases with the overset mesh, where internal parts (solids) are moving. These have worked nicely.

Thanks in advance.
