Massively Parallel Computation of Accurate Densities for N-body Dark Matter Simulations using the Phase-Space-Element Method
Ralf Kaehler
This paper presents an accurate density computation approach for large dark matter simulations, based on a recently introduced phase-space tessellation technique and designed for m…
A new approach to simulating collisionless dark matter fluids
Oliver Hahn, Tom Abel, Ralf Kaehler
Recently, we have shown how current cosmological N-body codes already follow the fine grained phase-space information of the dark matter fluid. Using a tetrahedral tesselation of t…
Tracing the Dark Matter Sheet in Phase Space
Tom Abel, Oliver Hahn, Ralf Kaehler
The primordial velocity dispersion of dark matter is small compared to the velocities attained during structure formation. The initial density distribution is close to uniform and…
Adaptive Mesh Fluid Simulations on GPU
Peng Wang, Tom Abel, Ralf Kaehler
We describe an implementation of compressible inviscid fluid solvers with block-structured adaptive mesh refinement on Graphics Processing Units using NVIDIA's CUDA. We show that a…
