waterbender is on a distinguished road
I am trying to solve a heat transfer - CFD problem as shown in the picture using buoyantSimpleFoam for a steady state solution.

I generated the mesh in fluent and converted it using fluent3DtoFoam. I have attached all the files I am using. For some reason, there is divergence being detected. I cant seem to find a solution. Can someone check it out. Thanks
