Default Poisson solver - orthogonal grid
Posts: n/a

can you recomend me some solver for Poisson equation in rectilinear nonuniform grid? I tried blktri from FISHPACK, but it produces range check errors. Do you know some other cyclic reduction solver, or some iterative solver easy to use on structured grid?
