raw17 New Member subhendu Join Date: May 2012 Posts: 10 Rep Power: 13	Hello Everyone, I am doing a LES channel flow simulation in openfoam. For some of my results I have to modify my velocity field using Newton method. I would like to recompute pressure for that modified velocity fields. I dont understand how to solve pressure Poisson's equation in OpenFoam. Can I take the grad(UEqn) and do something like this solve(grad(UEqn) == -fvc::laplacian(1,p)); or something else? Thankyou Subhendu Last edited by raw17; October 22, 2013 at 11:58.
