Hello Foamers,

First of all I apologize for being a newbie (noob). But I am trying to learn openfoam by my own. And it gets really difficult when I encounter such problems.

From some time I have been trying to simulate a problem involving heat transfer between fluid and solids, using chtMultiRegionSimpleFoam for the case of a ladle which is used in continuous casting of steel.

I created the slightly complicated mesh using blockMesh. The mesh has three different regions i.e. two solid and one liquid.

My first doubt is that I created all the boundaries of these regions separately which means that for a common boundary there are two different face/wall which lies in the respective region. Is this fine?
for example if you see the attached figures: for domain0 I defined the curvedWalls and for domain1 I defined the same wall (using different vertices number) as sideLayerInnerWalls.

The second dumb doubt arose when I run blockMesh followed by splitMeshRegions -cellZones -overwrite as that did not create any domain*_to_domain* like mappedWalls in constant/domain*/polyMesh/boundary files as given in the tutorial. And that is also obvious that why a third boundary would be created for the common boundary whom I already assigned two different names!!

But at this I did not stop I was so desperate to run this that I modified the files in constant/* so that they match with the case given in tutorial.

I noticed that in the tutorial there were no common boundaries mentioned in constant/polyMesh/boundary file so I did the same with my case file.

and also in the tutorial the common boundaries in constant/domain*/polyMesh/boundary files were of type domain*_to_domain*, so I manually changed the boundaries named curvedWalls, sideLayerInnerWalls to domain0_to_domain1, domain1_to_domain0 and so on. I tried to keep the format same as well like:

  domain0_to_domain1
    {
        type            mappedWall;
        inGroups        1(wall);
        nFaces          4000;
        startFace       299600;
        sampleMode      nearestPatchFace;
        sampleRegion    domain1;
        samplePatch     domain1_to_domain0;
    offsetMode uniform;
    offset (0 0 0);
    }

But after setting the whole case with similar conditions in 0 and system folder I get this error:

Attaching the link for the whole case:

NOTE: domain0 is fluid, domain1 & domain2 are solid.

I would be very obliged if I may get some help for this case.

Thanks and regards,
Singh.
