topoSet and splitMeshRegions
 

Hello,

I am trying to modify a bit the tutorial folder multiRegionHeater. The 3 zones used in the tutorial is being simplified by a bottom water domain, top air domain and a thin solid domain separating the air and water.

The output of topoSet and splitMeshRegions are attached below. While topoSet has created 3 cell zones, split mesh is able to recognize only two zones, it is combining water and solid zone (as evident from the number of cells).

Any suggestion!

Regards,
Amod
