Trying to set up a chtMultiRegion case
 

Hi,
I am trying to understand the chtMultiRegion solver better, thats wy I am following these guidelines:

https://www.researchgate.net/publica...ction_moulding


I am stuck on page 27 "create and allocate the regions", I am not abble to get a patch0 entry in the polyMeshboundary.


Has anyone ever been able to follow these guidelines or have an idea what steps are missing from this document? Or better guidelines/examples for a simple 3d chtmultiregion case?



Thank you in advance!
