Enabling Technologies for High Fidelity Simulations

The progress realized in the development of enabling technologies that are essential in performing high fidelity computational field simulations is presented. These enabling technologies include geometry-mesh generation and adaptation, visualization and feature detection, virtual reality, parallel and distributed computing, and problem solving environment and framework. The development of toolkits, modular and portable libraries of functions associated with these technologies, will be described. In particular, the Geometry-Grid toolkit (GGTK), MiniCAD system, and Goggle, a visualization and virtual reality framework, will be introduced with complex applications. The application of these functions and toolkits to the development of customized packages for automated analysis and design involving complex geometry is demonstrated. Examples are presented to demonstrate the efficiency, economy, and accuracy of these approaches. The future vision and plan for developing these enabling technologies is presented.
