Abstract

The engineer working on conceptual design of engineering components is restricted by the precise requirements of most analysis methods. The development of a design can be greatly enhanced by the use of an analysis technique which allows a sketched geometric definition, automated development of the corresponding analysis model and rapid re-analysis given a design perturbation. This combination of features allows designers to experiment with radically different designs and to control an intuitive design optimisation based on their own experience but guided by the analysis results. The Boundary Element Method (BEM) is particularly well suited in this area because of the increased speed and reliability of automatically modified meshing. This paper describes the implementation of an Object-Oriente
