Spatially Adaptive Projective Integration Schemes For Stiff Hyperbolic Balance Laws With Spectral Gaps
Julian Koellermeier, Giovanni Samaey
Stiff hyperbolic balance laws exhibit large spectral gaps, especially if the relaxation term significantly varies in space. Using examples from rarefied gases and the general form…

Shallow Water Moment models for bedload transport problems
José Garres-Díaz, Manuel J. Castro Díaz, Julian Koellermeier +1
In this work a simple but accurate shallow model for bedload sediment transport is proposed. The model is based on applying the moment approach to the Shallow Water Exner model, ma…

Projective Integration Schemes for Hyperbolic Moment Equations
Julian Koellermeier, Giovanni Samaey
In this paper, we apply projective integration methods to hyperbolic moment models of the Boltzmann equation and the BGK equation, and investigate the numerical properties of the r…
