Flow Visualization for Multiblock Multigrid Simulations
Multiblock multigrid finite volume methods based on hexahedral control volumes are computationally efficient and widely used for solving the Navier-Stokes equations. Due to the enormous amount of data generated during an instationary 3D simulation visualization plays an important role for problem analysis and development. Two different approaches for the interactive steering of multigrid computations in combination with the IRIS Explorer visualization package are investigated. The strategies for the visualization of complex multiblock grids which are presented are based on a new visualization data type, on a concept for the reusability of available visualization modules for curvilinear grids, and on a special algorithm for particle tracing, which does not depend on the connectivity information between blocks.
