how to solve in polar co ordinates in openfoam for chtMultiRegionFoam
 

Hello foamers

I am attaching a top view of the domain diagram where inside is a cylinder and outside is cooling medium(air)
am using chtMultiRegionFoam
but I need to solve the cylinder energy equation in polar co-ordinates

can anyone tell me how it can be done

Thank You

i'm not sure if that can be done with openFOAM.
i think openFoam uses cartesian coordinates.
i don't know if there is a utility that can do the
transformation for you, back and forth.
