SUMMARY:Computational Challenges of Numerical Simulations of Convection in
 side Stars
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics, Physi
 cs\n\nComputational Challenges of Numerical Simulations of Convection insi
 de Stars\n\nKupka\n\nNumerical simulations of convection have become a wid
 ely used tool in stellar astrophysics to investigate the interaction of co
 nvection with stellar pulsation, energy transfer, mixing, and the generati
 on of magnetic fields inside stars. Such simulations have to account for p
 hysical processes which occur distributed over many orders of magnitudes i
 n both space and time when modelling the dynamical evolution of the veloci
 ty field, the thermal structure, and other variables describing a star in 
 a statistically self-consistent manner. In this talk the principle challen
 ges of numerical simulations of stellar convection, in particular with res
 pect to simulations of entire stars, applications to stellar evolution, si
 mulations of turbulent stellar convection, and related topics will be addr
 essed.  Some of these challenges may be eased by suitable computation
 al procedures while others require statistical modelling alongside numeric
 al simulations which currently cannot be derived from first principles alo
 ne. Examples for both scenarios will be given.<br /><br />For access to sl
