multigrid
hi all, There are a lot of multigrid source codes available in net; but as far as I know these codes incorporate only Dirichlet boundary conditions for elliptic equations. Can anyone tell me a code which can be directly coupled into my code for solving pressure poisson equation (for nonuniform grid also)? Thank you

Re: multigrid
Poisson equation is also an elliptic equation. Pressure Poisson equation is a linear equation, I feel it wont be difficult to write your own code.
