Instead it has gravity and drag terms as the driving force. I can include it into OpenFOAM as: div(phi,U) == gravity + drag However, I can not include the continuity equation with this one. The solver does not compile when I try fvm::div(phi) or fvc::div(phi) I know that in simple algorithm, the continuity equation is included in the pressure equation. But i don't have to solve for pressure, it is not anywhere in the equations. How can I do it?
