Glimm’s Method for Relativistic Hydrodynamics

We present the results of standard one-dimensional test problems in relativistic hydrodynamics using Glimm’s (random choice) method and compare them to results obtained using finite differencing methods. For problems containing profiles with sharp edges, such as shocks, we find Glimm’s method yields global errors ~1-3 orders of magnitude smaller than the traditional techniques. The strongest differences are seen for problems in which a shear …
