Default Splitting the mesh into regions creating a problem

Dear all,

1. I have created mesh using snappyHexmesh which contains two regions.

2. Now, I used 'setSet' method to convert one patch region into cellZoneSet.

3. Then, I used 'splitMeshRegions -overwrite' to split the mesh into regions, but it creates large amount of domains which are not necessary.

What meshing parameters might be the problem?

The domain of the region is arbitrary and I have attached an image of two regions after meshing from snappyHexMesh.

Image1: Surface with two regions.

Image2: Small internal region.

Any leads will be appreciated.

Additional option maybe is useful, like -cellZonesOnly
