Hi,

I have a problem which consists a gyroid fin. I am analysing the heat transfer around the fin. The case has two geometries, including a heated boundary and fin section. The heated boundary has the constant temperature of 400 K and the fin's initial temperature is 300K. The heated boundary is attached to the fin and around these two geometries, there is an air enclosure which has the temperature 300 K. The air velocity is 5 m/s at the inlet. All geometries are from .stl version. However, the problem is my openfoam program doesn't run properly for this case. I mean after few iterations it is stopping. I am using the chtMultiRegionFoam solver . This case initially, properly run for circumferential fin. However, when I changed the geometry the case doesn't work. Also, I didn't change any of boundary conditions. Can someone help me on this regards. ? I really need the help.

Here I am attaching my log files and script files for your reference
