i am trying to solve incompressible flow.. i am writing code in Fortran.. doea anybody know any inbuilt programs or libraries by whihc poisson equation can be solved easily... as writing the fast poisson solver code is difficult ... so let me know wht to do .... guys who have worked in this area kindly help me... cant use FFT as i am interested to solve general problems and not problems with only periodic boundary conditions..
kind regards
