hello, everyone :

I am a newbie of openFoam. I want to solve a simple like the picture below.

There are adiabatic at the wall region in the picture. There are constant convection coefficient at point 6~8,11,14~16 and constant heat rate imput at the bottom.

I have found the solver is chtMultiRegionSimpleFoam. but there are Multiple region. I think there is a simple case. do anyone can give me some recommend about solver? really appreciate~
