Leon is on a distinguished road
so i have the following question.
I have an incompressible flow with a prescribed velocity field for each time step and want to calculate pressure via Poisson equation.
Is it as simple as:

phi =
(fvc::interpolate(U) & mesh.Sf())

fvScalarMatrix pEqn(
fvm::laplacian(p) == fvc::div( fvc::div(phi,U) )

Thx for your reply!
