Hi, thanks for your answer.
It might be it, but how is that possible?
My mesh is created through a classic multi region snappy hex mesh, followed by "splitMeshRegions -cellZones -overwrite".

Hi,
if you get stair-stepped edges, you just have to play with the minimum edge length or, in case of very sharp edges, I recommend you to smooth out the geometry a little bit.

Hi,
Looks as if the internal boundary of the smaller and bigger cells do not exchange heat at all.
I assume you have used some 'merging'/stitching techniques to create the mesh ? I would rather...
