Abstract

In the mechanical engineering world, there is a growing interest to be able to create so called digital twins to assess impact to performance or response. Part of the challenge is to be able to include and assess manufactured geometry as opposed to nominal design intent, particularly for components that are sensitive to small shape variations. In this paper we show how the update of CAE models can be conducted according to a radial basis function mesh morphing based workflow. The CAE mesh of the nominal design is updated onto the actual one, as acquired form surveying a manufactured individual. The concept is demonstrated on a practical application, the wing structure of the RIBES experiment, showing how the new proposed method compares with a traditional one based on the reconstruction of the CAD model.
