Finite Difference Solution to Poisson's Equation on Irregular Domain

  1. Feb 25, 2014 #1
    Hi,

    Are there any open source C or Fortran libraries for solving 3D Poisson'sequation on an irrefular domain? I'm having difficulty finding them.

    If not, is there any papers or recipes that would be useful so I could write my own? Speed is not a priority, I just need anything that works.

    Thanks

    Even with this question, Google is your friend:

    The FISHPACK library should give you a good starting point.

    ... except it only handles regular domains and grids (in several different coordinate systems).

    If you want to solve in a completely arbitrary region, I would look for a finite element or finite volume code. Google is your friend, again.
