Abstract
The major drawback in three-dimensional shape optimization is the exce ssive computational time needed in spite of the use of parametric-type design variables. Therefore, in addition to parametrization we sugges t the use of several meshing levels to speed up the obtention of the o ptimal solution and to check the precision of the analysis by an error estimation. The combination of parametrization, multi-mesh and error estimation allows us to deal efficiently with three-dimensional shape optimization problems. Copyright (C) 1996 Elsevier Science Ltd
