Numerics and simulations for convection dominated problems

The most important challenges in numerical simulations consist in the development of codes for new problems, in the improvement of the performance of existing codes and its validation. In this paper I will focus on the second topic. For inviscid compressible and convection dominated flows, in particular for problems from magnetohydrodynamics and for flows through porous media we will demonstrate some tools which are useful for more efficient codes: local grid refinement based on rigorous a posteriori error estimates, artificial boundary conditions for problems in outer domains, higher order schemes, balanced schemes for problems with source terms and relaxation schemes.
