In this Section we summarize some recent developments in
numerical RHD based on non-HRSC methods. The corresponding
methods have been shown to be capable of simulating high Lorentz
factor flows with shock waves. Van Putten's approach, described
in
4.1, was originally developed for numerical RMHD.
4.2
is devoted to outline recent relativistic extensions of SPH
methods (originally developed for Newtonian hydrodynamics).
Finally,
4.3
describes the main properties of the relativistic version of the
beam scheme, a method based on the numerical solution of the
equilibrium limit of the non-relativistic Boltzmann equation.
