Hi!

To begin with I;m new to OpenFoam and have used it to simulate transition and free molecular flow past bluff bodies.

I now want to conduct a study on Rayleigh-Bernard Convection in compressible fluids. so far the only solvers that I have come across (buoyantBoussinesqPimpleFoam) is applicable only for incompressible flows.

My basic query is:
1) If incorporate gravity in dsmcFOAM and sincedensity is not explicitly defined, will it accurately describe what Im looking for?

2) If I just copy the file g from "/opt/openfoam6/tutorials/heatTransfer/buoyantBoussinesqPimpleFoam/BernardCells/constant/g" and paste it in "/constant/" of my dsmcFOAM case file, will it work out?

Thanks!
