Adiabatic hydrodynamic tests
The results from a set of 1-D, 2-D, and 3-D hydrodynamics test are presented here. Many tests are compared directly with the compilation of 1-D and 2-D tests by Liska and Wendroff (L&W). In addition to the L&W tests, extensions include 3-D tests with known analytical solutions, a more severe striping instability test and some radiative test models (not available yet).
Liska and Wendroff Riemann tests
A suite of 1- and 2-D Riemann tests, performed with a representative set of hydrodynamics codes has been published by Liska & Wendroff (2003, SIAM J. Sci. Comput. 25, 995) and are available on their website (for convenience, a PDF copy of the article is provided for download on this page, but the interested reader should also refer to the original authors' site for any updates or corrections).
Test results and test code
Fyris Alpha was used to perform all the L&W test suite, and in addition some extensions/clarifications of the tests.
Fyris Alpha performs all the test problems very well, and produced results equal or better than any of the L&W test codes for many problems, in particular the extremely strong shock Noh problems.
All the results along with animations and/or key frames are available through the menu links to the right.
Note, the test results here are being updated as improvements toFyris are tested, so they should be considered a live record. WhenFyris is released, the complete set of problem code and initialisation files will be included.
