Thank you very much for this code. I've been able to make a comparison for the velocity solutions on different meshes.
I have a problem comparing pressure however, I get high errors (e+09) even if the solutions are not so different. I have an equation system with three systems, advection-diffusion, pressure projection, pressure correction, a second order approximation for velocity while a first for pressure. Any idea? Thanks again. Lorenzo Il giorno 19/giu/08, alle ore 01:54, Roy Stogner ha scritto: > > On Wed, 18 Jun 2008, John Peterson wrote: > >> We would need a little more info before we could say for sure.
