Description
The interaction of supernova remnants with interstellar clouds can produce dense gas aggregations which eventually get compressed enough to form prestellar cores. Numerical simulations of shocked clouds by isolated supernova remnants help to filter necessary conditions for core triggering and to enlighten the role of individual physical processes involved like magnetohydrodynamics, radiative cooling, (anisotropic) thermal conduction and self-gravity. The substantial complexity of computational models requires the use of efficent and, most notably, robust numerical methods. I will report on such numerical issues with perspective regarding a treatment of time-dependent ionization and rudimentary chemistry.
