Particle Methodsarticle methods relate to other approaches (finite difference, finite element and spectral methods) and survey particle methods. Sections 2, 3 and 4 focus respectively on particle-mesh (PM) methods for collisionless systems, particle-particle/particle-mesh (P.m) methods for correlated systems and fl

Why Ultrarelativistic Numerical Hydrodynamics is Difficultn. The numerical code is an adaptation of the WH80s Newtonian radiation hydrodynamics code described by Winkler and Norman in these proceedings. Shock fronts are treated by the method of artificial viscosity. We derive the equations of motion for an ideal gas with artificial viscosity in Eulerian an

Neutrino Transport in Relativity black holes. It uses a Lagrangian hydrodynamic formulation as a framework. The method is of mediocre accuracy, but it can handle all cases efficiently. The second method of solving the transport equation is for use in cosmology. In this case all velocities are of the same size and an explicit monot

Numerical Relativistic Gravitational Collapse with Spatial Time Slices while the Lagrangian observer is one at rest in the fluid. We can define an observer at an event in spacetime by giving his 4-velocity at that event. The path through spacetime taken by the observer is called the timeline of that observer. In flat Minkowski spacetime (the spacetime of special relat

https://doi.org/10.1007/978-1-4302-0158-8. The transport equation for a moving radiating fluid is presented in both a fully Eulerian and a fully Lagrangean formulation, along with conservation equations describing the dynamics of the fluid. Special attention is paid to the problem of deriving equations that are mutually consistent in each
