The computational grids for the calculations with the inhouse Navier-Stokes Codes are solely generated with tools developed at the Institute. The idea to build the grids is to set up a mechanical vibration model, where the grid nodes interact with springs and the grid nodes themselves are mass points. This procedure can be applied to generate structured grids for calculating the flow around linear turbine and compressor cascades with periodic O-Type or C-Type grids. Furthermore, it can be used to set up grids for tip-leakage computations where you have to mesh the region within the blade itself. The programm is a powerful and easy to use GUI, based on the portable C++ WXWindows Library, so it can be used on all Win32 and Unix platforms.
