TYCHO comes with several examples. In the parameterfile subdirectory
the parameterfiles for these examples can be found. For several of them initial
conditions are present in the subdirectory initial conditions. Here are some examples shown. One example is a 2D Kelvin-Helmholtz instability, as shown in the figure below. The initial conditions are set up with a density contrast, two layers of lower density gas with a constant velocity and a small velocity disturbance at the contact layers of the two density gradients. The velocity disturbance is defined as follows in the make ic.c file. Movie of a 2D TYCHO simulation of a Kelvin-Helmholtz Instability.
A second example is a small Toytown to demonstrate TYCHO's handling
of obstacles in the wind flow. At the beginning an obstacle distribution is
read in (please adapt the parameterfile for your own pahts for the files and
the output. A constant wind-flow from the left to the right blows through
the "city". One can study the turbulence, the regions with high velocity and
Another example
includes two wind-generators (e.g. ventilators or turbines) generating a wind-
In the last example two wind generators (e.g. ventilators or turbines) generating a wind-flow in the same direction through a tunnel. Several circle-shaped marker-fields are set up in that scenario. See the figure below for some visualizations of this configuration.
