Hello everybody,

Did anybody already modify the simpleFoam solver to include a body force term, i.e. gravity. I would like to add that and look for some hints.

Thanks for all advice

look at buoyantFoam, it is in there

thanks, right I just look at that. I'm new to OpenFoam so it might take me a while to get into the code. buoyantFoam uses a variable density as I understand it, whereas I treat a constant density case.

I want to let the fluid move driven by gravity. Is it maybe simpler to just define the pressure gradient instead of including it in the solver? I guess this is possible in OpenFoam ;-)

twoLiquidMixingFoam is incompressible, try that

[Ladnam]

Is this the last word in this case?

Is it not possible to model steady-state, single phase, incompressible, laminar flow with gravity in OpenFoam?

I also want to try this. Did you find the solution?

Thanks
