A high speed collision between two gas spheres where one of the impacting spheres is 1/20th of the mass of the other. The spheres have a temperature profile so that they are in gravitational equilibrium with their NFW density profiles.
Hydrodynamical test that can be run with and without self-gravity of the gas. The results with and without gravity are quite different.
Tests ram-pressure and viscous stripping.
If there is an analytic solution to the test put this (or a reference to it) here.
List published/posted papers involving this test here.
Relevant background reading, or similar tests to be referenced here. This can also cross-reference other pages within this wiki.
See unit description for the Wengen 3 test.
NB: The smaller impacting sphere is a rescaled version of the larger sphere. The mass ratio between the SPH particles in the small to large sphere is 2:1. Change if necessary. Initial separation and velocity are 500kpc and -600km/s.
Add the initial conditions files here. Please make sure that your file format is described in File Formats.
It would be good to always add the following: Please see File Formats for a description of the above file formats and a collection of conversion tools.
Describe here how the test is analysed and how it can be compared with results from other simulations, or to analytic results. It would be helpful to include a link to the analysis software used. It would be good to always add the following: Please see Analysis Tools to obtain the above analysis tools.
List here some example results from the test and describe their implications. Typically this will mean posting a couple of results figures.
Describe here the software used to perform the test and the results. We recommend using separate pages for each piece of software, though many can be presented simultaneously if this is more convenient. The former is more work, but is also more easily expanded upon in the future. Please store these tests in the namespace indcodetests, e.g.:
so that these do not appear in the menu in the side bar.
