SAETASS: Solver for Astroparticle Equation of Transport Analysis in Spherical Symmetry
SAETASS is an open-source numerical tool designed to solve the time-dependent transport equation for astroparticles in one-dimensional spherical symmetry. It uses operator splitting and a finite-volume framework to handle complex physical processes like advection, diffusion, and particle loss. The method allows researchers to accurately model non-thermal particle transport in environments such as stellar winds or supernova remnants.
