Advanced techniques for automatic finite element meshing from solid models
N. Sapidis, Renato Perucchio · Computer-Aided Design · 1989
A systematic analysis and evaluation of algorithms for automatic meshing from solid models is attempted. Focusing on algorithms that can be integrated into existing solid-modelling-based CAD systems, only three families of algorithms have been included: element extraction, domain triangulation, and recursive spatial decomposition. Algorithms in these families are particularly important because first, they tend to satisfy more closely the conditions for genuine automatic operations, second, they have been shown to be applicable to 3D (solid) domains, and third, they are well documented. A short discussion of expert systems dealing with finite element mesh generation concludes this paper.
