摘要：

Remeshing is an important problem encountered often in the FEM-simulation of metal forming processes. This paper describes the remeshing scheme developed at LAMI and IBF for the FINEL FEM-program. A novel automatic, two-dimensional, quadrilateral mesh generator is introduced. Mesh generation is performed by means of image processing and computational geometry. Other features of the remeshing scheme are boundary simplification, smoothing, and rezoning. Examples of applications are given.
