Abstract

This report contains a description of the flow solver for hybrid three dimensional grids, consisting of prismatic and tetrahedral (or hexahedral) cells. The following topics are described: 1. Edge Based Data Structure 2. Determination of the Auxiliary Grid 3. Basic Flow Solver 4. Boundary Conditions From the initial grid an auxiliarygrid of control volumes is determined. The governing equations are solved on the auxiliary grid and fluxes over the boundaries of the control volumes are computed. From the fluxes the new flow conditions in grid points are computed. This iterative process is executed until a certain number of time steps has been performed. A separate chapter deals with the parallelisation of the code based on domain decomposition. The decomposition is performed for the auxiliary grid. For the communication to be performed interface routines are used. Furthermore the report contains a description of the adaptation module for local refinement of hybrid three dimensional grids, consisting of prismatic and tetrahedral cells. The main topics are: 1. Grid-Adaptation Indicator 2. Grid-Adaptation Algorithm
