Re: [FLASH-USERS] 2D gravity

The only new gravity support (for the multigrid solver) in the next
release will be for 2d cylindrical axisymmetric isolated boundary
conditions. Also, 2d spherical will be newly supported in the multipole
solver.

Is it 2d cartesian isolated boundary conditions that you'd like?
