Cosmological Simulations with Adaptive Smoothed Particles Hydrodynamics
Hugo Martel, Paul R. Shapiro
Abstract
We summarize the ideas that led to the Adaptive Smoothed Particle Hydrodynamics (ASPH) algorithm, with anisotropic smoothing and shock-tracking. We then identify a serious new problem for SPH simulations with shocks and radiative cooling --- false cooling --- and discuss a possible solution based on the shock-tracking ability of ASPH.
