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
