Pressure Computation for incompressible cases

July 13, 2007, 04:53

Hello all,
does anyone of you know how the poisson equation for the pressure is solved internally for incompressible cases, because a comparison of the residuals of p with the residuals of cfx show big differences. In cfx p converges much faster than the velocity, whereas p in openfoam converges much slower than the velocity, although the booundary conditions are the same.

Cheers
Florian

Are you calculating a transient or a steady state case?
