Abstract

An adaptive mesh refinement procedure for shape optimal design J. Canales, J.A. Tarrago, A. Hernandez Department of Mechanical Engineering, Faculty of Engineering, University of the Basque Country, Alda. de Urquijo s/n. 4^013 Bilbao, Spain ABSTRACT In this paper we present a procedure for automatic mesh generation specifically created for shape optimal design problems. This procedure is implemented as a module in a general system for shape optimal design of linear elastic structures. The module provides the mesh generation and its adaptive refinement. It works in a whole automatic way. The input is the geometric definition and the result is the refined mesh. First a basic mesh is generated using conformal mapping concepts and second the basic mesh is refined using an error estimator based in the strain energy density function and -h and -p remeshing techniques. Some samples of shape optimal design solved with these concepts are presented. INTRODUCTION Shape
