AUTOMATED SHAPE OPTIMIZATION USING PARAMETRIC SOLID MODELS AND p-ADAPTIVE FINITE ELEMENT ANALYSIS

摘要

A shape optimization capability which is fully integratedwith geometry data is developed in this paper. A key feature ofthe system is the direct use of parametric solid model as theprimary design model for shape optimization. This choiceleads to a tight coupling between optimization and geometry, ahighly desirable feature for an automated design environment.The approach exploits the parametric engine of the solidmodeler to update the geometry at the end of each iteration.Responses are generated using polyFEM, a p-adaptive solversupported by a fully automatic three dimensional p-elementmesh generator. It is illustrated that the use of p-adaptivetechnology and parametrized solid model assist us in achievinga high degree of automation.
