Let me announce a 3D boundary condition generator for TYCHO - tychoBCG3D. With tychoBCG3D you can extract boundary conditions from point data, such as 3D scans (e.g.kinect) or STL data from CAD applications for TYCHO.

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. It is freely available for Windows as well as for Linux and it is Open Source.

TYCHO offers you:

* Obstacle - Gas interaction

* Heat-diffusion within obstacles

* Thermal-exchange between gas and obstacles

* Viscosity (Sutherland's law)

* Gravity as a constant background field

* Inclusion of marker-fields, which are advected with the velocity-field of the gas

* Wind-emitters

* Up to six different boundary conditions (easy to implement your own)

* Four different filetypes (including VTK)

* A graphical user interface to set up all simulation parameters

* An easy to use initial condition generator for 2D and 3D data to extract boundaries from pixel graphics and STL/point data.
