Hello all,

I have meshed an STHX with cell zones for hot and cold fluid and walls successfully.

My issue is I am not able to remove the bounding box created by blockMesh, the white region in image.

I thought it should have been gone since I am placing my locationInMesh point in the geometry itself.

I have used the tutorial from chtMultiRegionFoam for snappyHexMesh.

Thanks.

I am trying to follow this post.

Background Mesh in snappy with multi domain (CHT)

I will update if successful.

Thanks

Alright.

That was helpful.

After using sHM for multi-region meshing, we have to remove the background mesh, by default it is not removed (as supposed to, since we give locationInMesh).

Here are the steps given from above link:

 setSet -batch batch.setSet

where batch.setSet contains

cellSet isolation new zoneToCell cellZone1
cellSet isolation add zoneToCell cellZone2
...//add how many cellZOnes you want to keep with "add" argument 
cellSet isolation subset

and later:

subsetMesh -overwrite isolation
