Need to Solve Elliptic Problem

Can anyone help lead me to a fortran program to solve an elliptic PDE on a non-uniform grid? The geometry is a 2D rectangle. I just need something simple to use that doesn't have to be super fast. Please respond to this post or to me directly:

Thank you

Dear Friend

Hi. SOR and ADI schemes are simple and robust methods. You can find them in any CFD textbook.

Good Luck

Re: Need to Solve Elliptic Problem
If you need an open source Fortran program look at CORA available as a Special Purpose program of PHOENICS family.

If the CORA is over-complicated (chemistry, radiation etc), I recall that there should be more simpler (1D/ 2D/3D, steady/unsteady) open- source codes for the solution of elliptic conservation equations created in the mid-nineties at CHAM for educational purposes which have not yet found their ways to cfdSHOP. If I am not mistaken, they all have been circulating around under the USSR (User Source Software Routines) name. Ask CHAM whether they are still alive.
