Abstract:

The present work shows some of the typical computational tools and algorithms which are often applied in industrial optimization. The industry usually has existing CAD and CAE procedures that can handle large-scale finite element calculations for complex geometries. Structural optimization using TOSCA structure helps to find optimized design proposals in a very early phase of the product development cycle and dramatically reduces the overall development costs and time. In the industry structural calculations is often done by finite element modeling. Normally, the degrees freedom of the finite element models is constrained by the capacity of computer power available for solving the model. Frequently, an industrial designer will also prefer to use his daily preprocessor for constructing the finite element models for the optimization.  The purpose of the present paper is to show that optimization allows to be conducted in an already existing CAD flow for large-scale models having a high number of degrees freedom, a realistic geometry and boundary conditions, which finally can be done in an earlier faze of design product which assure the robustness reliability of product.
