New Methods for Repair of Geometry and Topology of CAD Models

Abstract

The overall objective of this work is to introduce a drastically innovative technology for repair and automatic extraction of high-order geometric data from platform models developed with CAD (Computer Aided Design) software tools. The results will have applications to large-scale CEM analysis of low observable aircraft by high-order fast solvers as well as to a variety of other computational problems requiring high accuracy geometry representation. The effort carried out under this project was planned as an assessment of the current capabilities of GeomFix, a software system developed recently by Matis for efficient and reliable repair of geometric deficiencies in CAD models intended for use with computational electromagnetics methods.
