Scientific paper

The smoother particle hydrodynamics method is here extended to relativistic, self-gravitating spherical collapse and compared with an equivalent FEM code. A Galerkin weighted-residual technique successfully solved all instabilities. The results of the present method are noted to be generally smoother for a given number of particles and nodes, but are also in general agreement with alternatives.
