Dear All,


I have created a stl mesh using open3D from point cloud. This mesh was split into two domains as a patch and then added back using "surfaceAdd". Now, this mesh is implemented into snappyHexMeshDict.



I mesh is running well. But, when I do splitMeshRegion after some topoSet addition, it creates multiple domains, where my cellZoneRegion has only two regions and I need only these two regions.


The splitMeshRegion creates an extra domian which needs to be eliminated or added to the major region. How to do that? I have attached an image where the red color represents the extra domian created. It has only 3 face.


Below is the snippet of splitMeshRegion.

Region Zone Name
------ ---- ----
0 1 gland
1 0 tumor
2 -1 domain2


Sizes of interfaces between regions:

Interface Region Region Faces
--------- ------ ------ -----
0 0 1 278
1 0 2 3




Here "domain2" is the extra region created.
