Default Multiple domain interfaces on a single surface

Hello,

I'm having difficulty applying proper interfaces in a 3D simulation I'm trying to run. I have a two solids, overlapping partially, in an airflow, as seen below. Because of this, the top surface of solid 2 requires a solid-solid interface with Solid 1, and a solid-fluid interface with the surrounding air.

|.....Solid.1...|.....Fluid.....|

--------------------------

|............Solid.2..............|

When I apply both domain interfaces, I get errors saying:

"There are 2d regions in boundary 'Domain Interface Side 1' in domain 'solids' that have already been used." and "There are 2d regions in domain interface 'Domain Interface 1' that have already been used"

It seems to me that I should be able to partition or split the top face of Solid 2 along the line of contact, but I am unable to find any option to do so in Design Modeller, Meshing, CFX-Mesh, or CFX-Pre.

Any help would be greatly appreciated.

You can split the face in DM using a Body Operation with the "Imprint Face" option. Unfreeze Solid 2 and freeze all other bodies, then pick Solid 1 and Fluid for the operation, which will then imprint their faces on Solid 2.
