Automatic generation of coarse three-dimensional meshes using the functionality of a geometric modeler

Abstract

An automatic three-dimensional mesh generator suited for the generation of coarse three-dimensional finite element meshes is presented. The algorithm employs the three basic three-dimensional element removal operators and considers their application in a mode that selects the best shaped elements for the given domain. Consideration is given to the integration of this procedure with a general non-manifold geometric modeling system.
