TYCHO (TYrolian Computational HydrOdynamics) is a multidimensional compressible hydrodynamics code written in C and parallelized with Open-MP. A Lagrangian remap version of the Piece-wise Parabolic Method is applied. The code is based on the freely available VH-1 Package.

The simulation package is focused on gas-obstacle interactions and has special routines for obstacles in wind streams and advection of marker fields for  investigations of obstacle-gas interactions.

TYCHO comes with five different boundary conditions to choose from, namely Zero Gradient, Reflecting, Small Number Padding, Outflow, Inflow and Periodic. These boundary conditions can be attached separately to all edges of the computational domain.

To provide the user with a simple starting point for one’s own simulations, two OCTAVE scripts are provided to set up 2D initial conditions for TYCHO. The scripts are meant to generate initial obstacle and marker-field  distributions for TYCHO 2D simulation.
