The Parameter File

The code needs a parameter file at start up given as an argument (e.g. .$\slash$tycho parameterfile.txt). The file includes all important parameters such as

Note that the file needs to have 47 parameters, otherwise TYCHO would mix up things. The parameterfile for TYCHO version 0.93 an lower had 45 paramters. The difference is a viscosity switch and the heat-capacities for gas and the obstacles for the thermal-exchange between gas and obstacles - use tychoGUI for generating parameterfiles. One parameter disappeard in TYCHO version 1.0 compared to TYCHO version 0.93 and below: the thermal diffusivity of air.
A detailed description of all parameters follows:
