Default interFoam and static pressure

Actually i'm solving two phase flows in a single rotating cylinder with a modified version of interFoam which includes the centrifugal forces.

The problem occuring to me at the moment is the thing about the p_rgh field. I've already read the several posts in the forum and i agree with the states, that p_rgh is a modified pressure field created for more computational stability.

But how can i get the static pressure? Because when i compare my results of p with the static pressure calculated with fluent, the results aren't equal.

Can anyone help me with this problem?

Maybe this post helps you: p_rgh in OF 1.7
And be aware that in incompressible solvers you have to multiply some results by local density to obtain "real" values.
