While p and pmh (pd in OpenFOAM-1.5.?) are equivalent on orthogonal meshes they are not on non-orthogonal meshes and the difference is very important for buoyancy-dominated flows such as settling. settlingFoam is now written in terms of pmh (static pressure minus hydrostatic pressure) which used to be called pd but that confused too may people.
