Well-balanced treatment of gravity in astrophysical fluid dynamics simulations at low Mach numbers
P. V. F. Edelmann, L. Horst, J. P. Berberich +5
Accurate simulations of flows in stellar interiors are crucial to improving our understanding of stellar structure and evolution. Because the typically slow flows are merely tiny p…
