3.1 INTRODUCTION

Theoretical numerical modeling has become a third pillar of sciences in addition to theory and experiment (in the case of astrophysics, the experiment is mostly substituted by observations). Numerical modeling allows one to compare theory with experimental or observational data in unprecedented detail, and it also provides theoretical insight into physical processes ...
