Multiple domain/Multiple material problems... possible or not?
 
Hi FOAMers,

As above - can OpenFOAM handle multiple domain/multiple material problems with interior boundaries allowing fluid to pass between each domain?

I know the fluentMeshToFoam converter cannot handle multiple materials, but I am not sure whether that is a converter limitation, or a limitation for OpenFOAM in general...


(The multiple material points are required for post processing - we are looking at fluid compositions over time in multi-cell chambers)


If OF can handle multiple material/domain problems; I'm happy to go off and hunt down the technique myself, but of course any guidance is very welcome! :)

You can do this using a number of techniques:
1) conjugateHeatFoam : see http://www.cfd-online.com/Forums/ope...-openfoam.html but this is only available in the -dev versions.
2) chtMultiRegionFoam
3) You can "map" transport properties between submeshes and a main mesh.

Out of those 3, I prefer conjugateHeatFoam.
