Hello to every one,

I am working on a chtMultiRegionFoam simulation on OpenFOAM 7. There are 20 different regions: 14 are channels with the same fluid and the remaining 6 are solid, all of these with different properties. This is a 3D simulation.

I built mesh using ANSYS, so the first step was to convert the mesh using fluent3DMeshToFoam.
After that, I launch splitmeshregions -cellzones -overwrite. This command creates my 20 regions

All the fluid regions as the same BCs and properties. I am wondering if I can collect all these 14 channels under one single region.
I tried to search over splitmeshregion, but I was not able to figure out the problem.

Thank you for your help.
