interFoam and static pressure

MatP · July 11, 2012, 14:56

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?

And be aware that in incompressible solvers you have to multiply some results by local density to obtain "real" values.
