Topology Generation within CAD Systems
The process of extracting reusable topology data from a 3D multi-block mesh created within a CAD system is analysed for two CAD systems: CATIA and ICEMDDN. A general method is derived, applicable to arbitrary CAD systems. For this purpose, the CAD system is modelled by a small kernal of high level capabilities. The principle of a general “Record/Replay system” for mesh generation is sketched.
