Cosmological Simulations with Adaptive Smoothed Particles Hydrodynamics

11/2001;
Source: arXiv

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.
