Abstract
A complete software system for the prediction, rendering, assessment, and reduction of errors in CFD simulations is presented. A viscous Error Transport Equation (ETE) solver is used to predict the spatial discretization errors inherent in every CFD simulation. Errors in various quantities of interest may be computed through an error function library. Techniques for visualizing these errors in two and three dimensions have been developed for scalar and vector fields. This, along with a Richardson extrapolation utility, allows for a quantitative analysis of grid-induced errors. In addition, the software system contains a mesh adaptation capability for three-dimensional mixed-element unstructured grids. The complete package is demonstrated on realistic applications, and represents a unique analysis tool for solution verification.
