Hi, I've created a subMesh
 

Hi,

I've created a subMesh from a cellSet of a parent mesh and solved for some fields on the subMesh. Now I'd like to transfer the values of those subMesh fields back to fields on the parent mesh. Any ideas on how to do this in OpenFoam?

Thanks and best regards,
Helmut

mapFields or modify subsetM
 

mapFields

or modify subsetMesh to store the cellMap(), faceMap() etc from fvMeshSubset and use these to map back.

These maps are from the subsetted mesh back to the original

fvMeshSubset gives you the map
 

fvMeshSubset gives you the mapping data and the interpolation functions - yo should not need anything else.
