Piastra

mrkondratyev•PUBLIC

A user-friendly teaching framework for studying computational (astrophysical) fluid dynamics & MHD. The code implements 1D/2D linear advection, Newtonian and SR gas dynamics, MHD, and diffusion solvers, using a finite-volume approach. NumPy library is used for code clarity and performance.
