I'm trying to simulate a buoyancy-driven flow in a box using rhoPimpleFoam. It isn't reading the "g" gravity file, and the results are clearly that of simple diffusion; e.g. it is ignoring all gravitational effects. Is there some place in the inputs to get rhoPimpleFoam to apply gravity/buoyancy effects?

Hi,

Please look at the solver in combustion rhoReactingBuoyantFoam. From the differences in rhoReactingFoam and rhoReactingBuoyantFoam , you can figure out how to add gravity to rhoPimpleFoam. Just look at the pEqn.H File and CreateFields.H file.

Alos have a look at this wiki where gravity is handled :
