Abstract

As grid generation systems become able to deal with increasingly-complex geometric configurations, the need to evaluate the grids has also increased. Current evaluation techniques use both computations of grid quality measures as well as standard field visualization packages; unfortunately these techniques are often misleading and confusing, making effective evaluation difficult. Presented here is a new approach which uses a visualization hierarchy to display and highlight various aspects of grid quality: a new qualitative point cloud mode to assess the overall distribution of grid points; a new quantitative grid weathermap mode to present “at a glance” an overall measure of grid quality and to help isolate regions of poor grids; and a new grid browsing egg carton display for visualizing and stepping through the grid planes. Results for a variety of block-structured and unstructured grids are discussed and displayed.
