Abstract

Decomposition into mappable regions of a multiply connected planar domain for automating element meshing M.L. Luchi, S. Rizzuti Department of Mechanical Engineering, University ABSTRACT In the present paper a methodology is described whereby the subdivision of a multiply connected planar domain into mappable regions is automatically performed. The technique proposed, which was developed to be applied within an interface between a geometric modeler (B-rep type) and a 3-D BEM code for elastic stress analysis, can be as well applied to 2-D finite element discretization problems. At the present stage of development, the technique operates over planar domains which are externally and internally bounded by polygonal contours and may contain any number of circular holes. INTRODUCTION The wide-spread use of geometric modelers for designing engineer components has recently focused a considerable research effort on the development of integrated design/analysis systems and in par
