convergent prob. in solving poisson eq(neumann BC) -- CFD Online Discussion Forums

yf yap Guest Posts: n/a	for a poisson equation with neumann boundary condition on a rectangular domain, let's say 41x41 grid points, i coded a program to solve it. using ADI, i can only obtain solution after more than 1000+ iterations. questions: 1) what can be done to ADI in order to accelerate convergence? 2) normally, how many (roughly) iterations are needed to obtain the solution for this class of problem, poisson eq with neumann BC? any advice would be appreciated. thanks. regards, yfyap
