VGRID

Abstract

VGRID is a robust, user-friendly computer program for the generation of three-dimensional unstructured (triangular surface and tetrahedral volume) grids in geometrically complex domains. The base code (VGRID3D) has been developed by ViGYAN, Inc. under a NASA Small Business Innovation Research (SBIR) contract. Since completion of that project (1990), considerable extensions to VGRID have been developed at NASA Langley Research Center. These extensions are an outcome of several years of research, development, extensive application, and user-feedback improvements. VGRID is a key component to the NASA unstructured-grid software system TetrUSS, a recipient of the 1996 NASA Software of the Year award. Along with a graphical user interface utility GridTool and a grid post-processing program POSTGRID, the VGRID system provides a reliable tool for the fast and convenient generation of unstructured grids around complex configurations. The code, in conjunction with the unstructured-grid solver USM3D and post-processing visualization program ViGPLOT has been widely used by many researchers and engineers from academia, industry, NASA, and other government agencies for the past several years.
