Hi,

I'm using the chtMulti-solvers. Finally I want to use chtMultiRegionRadFoam. But the chtMulti-solvers are very simillar, thus I'm using chtMultiRegionSimpleFoam at the moment, because I didn't get started chtMultiRegionFoam and chtMultiRegionRadFoam yet.

I want to model a heat transfer with a "frozen" velocity field. In my case I can define the velocity field as steady state. The heat transfer shall be solved transient.
To reduce solving-time I think about editing the solver to solve only the energy equation and not the velocity equation.
Does someone know if this is possible in general, or does someone has done that before?

So I thought about the time the machine needs to solve the case.
Does someone know if it is also possible to switch off the solving of the velocity field?

(Another question:
Does someone know if it is possible to solve incompressible insteat of compressible?
Maybe just by switching the density variation to zero? But where do I change that?)
