A cosmological multidimensional hydrodynamic code is described and tested.
This code is based on modern high-resolution shock-capturing techniques. It can
make use of a linear or a parabolic cell reconstruction as well as an
approximate Riemann solver. The code has been specifically designed for
cosmological applications. Two tests including shocks have been considered: the
first one is a standard shock tube and the second test involves a spherically
symmetric shock. Various additional cosmological tests are also presented. In
this way, the performance of the code is proved. The usefulness of the code is
discussed; in particular, this powerful tool is expected to be useful in order
to study the evolution of the hot gas component located inside nonsymmetric
cosmological structures.Comment: 34 pages , LaTex with aasms4.sty, 7 postscript figures, figure 4
