Evan,<br><br>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. <br>

Wondering if there is a version of Poisson gravity solver that works with the fixed grid? Or even better fixed grid with large blocks<br>
