Hi, Im new in OpenFoam but i want know in which files OpenFoam search for the variables for the heqn, peqn and ueqn. I want modificate buoyantFoam to incompressible cases maybe modificating the p*v=m*R*T equation (Does the buoyantFoam simulate compressible gases cases with this eq with bousinesq aproximation?).
