Geometry Management Support for Auto-meshing

Currently the focus of research and development effort for new meshing technology is on developing new algorithms for meshing. As a result of this some successful meshing algorithms have emerged, but true automeshing is still elusive. The generation of a meshed model ready for analysis is more involved than merely creating elements. Solid models created in CAD systems often need to be processed to ensure they are in a form suitable for meshing. In this process there are still several missing functions: geometry management, mesh quality optimisation and automatic mapping of the physics of the problem onto the mesh. This paper addresses geometry management support required for automeshing of solid models.
