Dear All,

for my Simulation I am in need of something like a Fluid-Fluid Coupling Condition for the chtMultiRegionFOAM solver. However scanning the tutorial gives me some Ideas, but no solutions at all. Which of the following is the fastest way to paradise?

  1. Using something like
    bottomAir_to_rightSolid
    {
    type directMappedWall;
    nFaces 0;
    startFace 1070;
    sampleMode nearestPatchFace;
    sampleRegion rightSolid;
    samplePatch rightSolid_to_bottomAir;
    offset (0 0 0);
    }
    but with directMapped?? Which startFace do I have to use?
  2. Creating a new BC like solidWallMixedTemperatureCoupled?? (I Know this is not that simple, but I hoppe I can handle this...
  3. Using something like a processor or coupled BC ?
It might be highly impolite, but I would also appreciate some examples for these BC's. I can't find them in the Forum.

Thanks in advance!!

Tobias
