I am interested in modeling an incompressible turbulent flow taking temperature into account. I want to fix the temperature on different boundaries and see heat flux through the boundaries.

I have changed the program that can extract the heat flux (wallHeatFlux program) so that it works for the buoyant*Foam solvers. My question is what solver to use? I am not interested in solving for the solid part so chtMultiRegionFoam appears not to be appropriate. Are the buoyant*Foam solvers the relevant solvers and can I set g=0 (mostly conductive flow)?
