Let me announce TYCHO - TYrolian Computational HydrOdynamics, which you will find at http://www.tycho-cfd.at/
It is an open-source project.
TYCHO is a multidimensional (1D/2D and 3D) compressible hydrodynamics code written in C and parallelized with OpenMP. A Lagrangian remap version of the Piecewise Parabolic Method developed by Paul Woodward and Phil Colella (1984) is applied. The code is based on the freely available VH-1 Package. It solves basically the euler equations for inviscid gas. The simulation package is focused on wind-tunnel experiments and has special routines for obstacles in wind-streams and advection of marker fields for investigating obstacle-gas interactions. In addition momenta and their direction on obstacle surfaces and thermal diffusion can be studied within in your simulation. As a future step inclusion of viscosity at boundary layers will be included. Gravity is included as a constant background-field and a stratified atmosphere can be set up, if needed. In addition a graphical user interface called tychoGUI can be downloaded to make interaction with TYCHO an easy task.
