PISO Questions

Hi Foamers,
I have two questions concerning the implementation of PISO in OpenFoam. 1- What exactly does the comand ddtPhiCorr (rUA, U, phi)? I think it does the correction of fluxes on the surface of control volumes, but I am not completely sure. If this is right, why it is done after adjustPhi (phi, U, P)? What it is being done on this two steps? 2-After solving the momentum predictor, why it is done immediately the correction of pressure boundary field? Is it possible to do it? Can this done using p.boundaryField().upadteCoeffs();?. I am asking this because I am trying to simulate a the flow of a fluid where extra stresses are important, and, I am getting the right velocity profile but the wrong value of pressure gradient. I think I am not actualizing properly the pressure field, but I am not sure how i csn do it correctly. Regards, Titio |
