Default p_rgh residual diverging for chtMultiRegionFoam case with cyclic boundary conditions

Hello all,


I am attempting to get a case involving a smooth duct with a metal region on bottom to run. I am using chtMultiRegionFoam and so far get decent results if i define the boundary conditions with the standard input output pressures and velocities but run into trouble when I include cyclic boundary conditions. For some reason I am getting a divergence in p_rgh, among other errors, when I run it. I have tried many things and cannot seem to figure this one out. I can get a regular cyclic case to run fine just not with conjugate heat transfer.


I am new to this, so I am not sure what would be necessary to diagnose and am just posting the 0 directory. Any guidance is appreciated.



Thanks,
Caleb

You should post your entire case file. With only the /0 directory, we can't see how the neighbouring patches are defined, those should be in the boundary files located in /constant.

The case file is too large for me to post. How do I get around this.Attached is the boundary file.


Thanks,

Caleb
