snappyHexMesh for porous - multiple regions without boundaries
 

Hi

I am using sHM for porousSimpleFoam
As a starting point I used snappyMultiRegionHeater with 2 stl files as input without splitting the mesh
The problem is that sHM defines a boundary between the porous zone and the non-porous zone - when I remove the (wall) boundary from constant/polyMesh/boundary I can run the the application

How can I run sHM with two regions seperated by a stl surface without getting a boundary between the regions?

(If there is a better way I would be happy to know ;)

Thanks in advance
