Hello! I am adjusting the CHT tutorial for OpenFOAM and Nutils. I have 2 questions about this. The first is about OpenFOAM. I am using the buoyantBoussinesqSimpleFoam solver, since i want to solve the heat transfer in a turbulent fluid. (i have neglected the buoyancy term by putting the gravity to…

[image] Makis: Adding temperature to simpleFoam should also be supported if it registers temperature the same way as the standard OpenFOAM solvers, but why not use the full buoyantSimpleFoam? Why do you need the Boussinesq approximation? Okay, good to know for future other solver uses! In the…

I think it is easier if i post the files I am using for OpenFOAM. First the normal settings fvSolution.txt (1.6 KB) preciceDict.txt (426 Bytes) controlDict.txt (1.3 KB) fvSchemes.txt (1.5 KB) transportProperties.txt (1.1 KB) turbulenceProperties.txt (1.1 KB) g.txt (933 Bytes)

and the 0 folder. k.txt (1.5 KB) nut.txt (1.5 KB) omega.txt (1.5 KB) p.txt (1.5 KB) p_rgh.txt (1.4 KB) T.txt (1.4 KB) U.txt (1.4 KB) alphat.txt (1.6 KB) epsilon.txt (1.6 KB)

[image] CarsvO: I am using the buoyantBoussinesqSimpleFoam solver, since i want to solve the heat transfer in a turbulent fluid. I am not sure if this is a good reason to select this solver, but it is definitely supported. For the future reader: this is an incompressible (with the Boussinesq …

[image] Makis: I am not sure if this is a good reason to select this solver, but it is definitely supported. For the future reader: this is an incompressible (with the Boussinesq approximation for density) steady-state solver. Is a modified simpleFoam also supported then? I might try that ou…

[image] CarsvO: Is a modified simpleFoam also supported then? I might try that out so i just add another temperature equation? Another option for me would be to modify the simpleFoam solver, however with some parameteres adjusted in the buoyantBoussinesqSimpleFoam, the equations will be the sam…
