Default conjugate heat transfer: turn off turbulence

Hello!

The solver chtMultiRegionSimpleFoam for conjugate heat transfer is for compressible and turbulent flow.
Is it possible to turn off turbulence and compressibility or is there another cht solver which is for incompressible laminar flow?
I'm new to Open FOAM and CFD and would like to start from a simpler problem and see the effect of compressibility and turbulence.

Thanks!

chtMultiRegionSimpleFoam is developed for compressible flows. It is not possible to simply switch OF solvers from compressible to incompressible. That's why there are seperate solvers for compressible and incompressible flows.

Turbulence is switched off in cht* solvers if you choose turbulenceType laminar. Most cht tutorials in OF use laminar flow.

Michael, thank you for your reply.
Is there incompressible solver for conjugate heat transfer?

I'm confused. The chtMultiRegionFoam is compressible solver. But in the tutorial example chtMultiRegionLiquidHeater the water density is fixed.
