GridTool: A Tool for Structured and Unstructured Grid Generation

GridTool is an interactive program for grid/geometry applications . Most grid generation programs represent geometry by a set of structured points which is not consistent with the Computer Aided Design (CAD) representation. The purpose of GridTool is to bridge the gap between the CAD and the grid generation systems. GridTool is designed primary for unstructured grid generation systems. Currently, GridTool supports VGRID and FELISA systems, and it can be easily extended to support other unstructured grid generation systems.

GridTool is part of Tetrahedral Unstructured Software System (TetrUSS). TetrUSS is an unstructured-grid flow analysis and design computational fluid dynamic (CFD) software system developed at NASA Langley Research Center. The goal is to provide a validated capability to non-CFD expert users for performing rapid aerodynamic analysis and design of complex configurations. Capabilities include rapid grid generation and inviscid flow analysis, and an emerging Navier-Stokes viscous flow analysis.
