Running chtMultiRegionFoam

arslanadeel · May 20, 2019, 11:00

Hi. I am trying to run some chtMultiRegion Simulations. Every tutorial follows as below:

blockMesh
topoSet
sliptMeshRegion
run Application

this is because they normally have one Mesh and then split them into MultiRegions.

However, in my case I already have two separate meshes, one for solid region and one for fluid region, I just put them into their respective constant/ploymesh directory and I am not using topoSet and splitMeshRegion commands. My check Mesh is ok on individual Meshes. however when I run the checkMesh on the same meshes in Multiregion case directory it fails.

I don't know whether the procedure I am doing is ok. Or I should try some other things.

Your question is wide open and it may have many possibilities

Couple of questions.

How did you mesh?
Can you please post your "boundary" file from respective polyMesh folder?
What error do you get?

Regards
