I have a complex gemoetry with five regions with heat transfer over multiple surface contacts. It is quite tedious to manually separate the contact surfaces into patches and apply thermal baffles there. CFX for instance is able to recognize overlapping surface areas and allows me to specify separate boundary conditions there. I'm wondering if OpenFoam can also do something like that with some preprocessing tool. I would supply multiple STLs for the separate regions, and would like OpenFoam to make the boundaries accordingly. An additional difficulty would be that the mesh would not necessarily be conformal with such an approach. Has anyone tackled a similar problem?
