Default Connecting meshes after cfMesh for multiRegion

Hey guys!

After getting really frustrated with snappyHexMesh, I decided to try cfMesh for my multiRegion case. My workflow:
1. make one Mesh for each region
2. use topoSet to define cell- and faceZones
3. mergeMeshes
4. splitMeshRegions

I am not getting any error and one nice mesh after that but the problem is that the regions are not connected.
So, how can I do that? My idea was to either use stitchMesh or createBaffles to get the "this_to_that" patches but I don't really know how to do that or if that is even the right way to do it.

Does anyone have an idea?

Hi Claudia

I would really appreciate that you could share more details about step 2, 3 and 4. Especially, how to implement those steps in cfMesh?

Many thanks.

Best Regards,

Hi guys,

Did you manage to merge nodes on the interface zones so mesh is comformal?

I ma struggling on how to do it. cfMesh do a nice work, but after mergeMeshes nodes at the interface are not connected...

Thanks in advance
