Methodology Improvements to Non-Uniform Rational B-Splines (NURBS) Geometry Conversion in BRL-CAD

Abstract

BRL-CAD is an open-source computer-aided design and analysis software package used as the foundation for vulnerability/lethality (V/L) analysis software suites in the U.S. Department of Defense. Conversion of pre-existing commercial vehicle information into formats analyzable by BRL-CAD often introduces geometric errors, most commonly in the form of overlaps between components introduced by meshing errors. Two improvements to BRL-CADs conversion methodology were implemented to automatically assist users in avoiding these problems. The goal is to produce analysis targets that satisfy a set of quality metrics relevant to V/L analysis in less time and with improved quality.
