Modern Astrophysics, and the study of Core-Collapse Supernovae in particular, require
an intense computational power and convenient code for different machines. A portable
versatile code IDEFIX is able to deal with these issues. This thesis demonstrates a
simulation of Core-Collapse Supernova with stable shock using IDEFIX.
The model has an outer accreting part and inner shock. The code provides an extensive
possibilities to efficiently modify the model for specific needs.
Throughout the work, we obtain standing accretion shock instability (SASI) with 3D
simulations, as well as observe how an outer convective shell with velocity perturbations
affect the shock and SASI for different perturbation profiles. Additionally, we provide a
way of analyzing those accreting perturbations which hints towards the future research of
this topic.
