We are developing GenASiS (General Astrophysical Simulation System) to study the explosion mechanism of core-collapse supernovae. The current version of GenASiS is suitable for large scale simulations and includes a mature implementation of magnetohydrodynamics as well as a general Poisson solver. As a science application of the code, we explore the capacity of the stationary accretion shock instability (SASI) in the post-bounce supernova environment to generate magnetic fields by adding a weak magnetic field to an initially spherical symmetric fluid configuration that models an idealized stalled supernova shock. We find that the SASI flows generate a significant boost of the magnetic energy. Implications for the magnetization of neutron stars are considered.
