Hi,

I am learning to use chtMultiRegionSimpleFoam by creating a 2D case with a solid box (called wall) on the floor encircled by air. The bottom of the wall has a temperature higher than the rest of the domain (500K for bottom wall and 300K for the rest).

I am using the tutorial planeWall2D to realize my case.

I have two domains: domain0 air and domain1 wall.
The interface between solid region and fluid region is defined by:
- wall_to_air for domain1
- air_to_wall for domain0

When I run the case I obtained this fatal error :

I don't understand because the patch wall_to_air doesn't need to be in the domain0, it is the interface of domain1.

Does anybody know where this problem comes from?
