The spectral element method (SEM) on variable-resolution grids: evaluating grid sensitivity and resolution-aware numerical viscosity
spectral element method variable-resolution grids
2014/12/19
We evaluate the performance of the Community Atmosphere Model's (CAM) spectral element method on variable-resolution grids using the shallow-water equations in spherical geometry. We configure the met...
The impact of numerical viscosity in SPH simulations of galaxy clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
A SPH code employing a time-dependent artificial viscosity scheme is used to construct a large set of N-body/SPH cluster simulations for studying the impact of artificial viscosity on the thermodynami...
