Hey Foamers,
I am an amateur in CFD and OpenFoam and I have been assigned to do a relatively difficult task( as far as my standards are concerned).
For starters, I am supposed to perform incompressible flow past a heated(having internal heat generation) rectangular cylinder using chtMultiRegionSimpleFoam.
Although, it seemed like a herculean task at first but I somehow managed to mesh both my regions (Domain and Cell) using salome and used ideasUnvToFoam to convert the mesh into OpenFoam readable format.
The issue which I am facing is I just cant get my solver to run. I am attaching my case as well as the errors coming when I run simulation. Please, please please somebody help!


On running Allrun script the following output comes:

I would have shared my case but its size is exceeding the allowable size limit.
Please Help!
