A fast spectral-multigrid Poisson solver in non-Cartesian geometries
Ankush Mandal, Oliver Gressel, Udo Ziegler +1
Accurate and efficient computation of self-gravity is essential in astrophysical fluid dynamics, particularly in spherical and cylindrical geometries where large radial dynamic ran…

A self-gravity module for the PLUTO code
Ankush Mandal, Dipanjan Mukherjee, Andrea Mignone
We present a novel implementation of an iterative solver for the solution of the Poisson equation in the PLUTO code for astrophysical fluid dynamics. Our solver relies on a relaxat…
