Evan,

It is not clear if you want to work with the uniform grid or with PARAMESH
with same refinement everywhere. Both are possible. We have tested the
uniform grid with periodic boundary conditions where it makes use of the
PFFT based solvers found in GridSolvers. The setup line can be tricky, and
we can help you with it if you need help. If you wish to use isolated
boundary conditions, we know of no reason why the multipole solver won't
work with uniform grid. We haven't tested it in a long time, but we expect
it to work either right out of the box, or with little work. If you plan to
use PARAMESH, then everything that works with AMR will work anyway. We can
provide more specific answers if you can narrow your question.
