Data analytics for simulation repositories in industry

Rodrigo Iza Teran and Jochen Garcke

Abstract


Simulations are used intensively in the developing process of new industrial products and have achieved a high degree of detail. In that workflow often thousand finite element model variants, representing different product configurations, are simulated within a few days or even overnight. Currently the decision process for finding the optimal product parameters involves the comparative evaluation of large finite element simulation bundles by post-processing each one of those results using 3D visualisation software. This time consuming process creates a severe bottleneck in the product design and evaluation workflow. To handle these data we investigate an analysis approach based on nonlinear dimensionality reduction to find a low dimensional parameterisation of the dataset. In such a reduced representation, similar model variants are organised in clusters and the influence of the input variables can be analysed along such a parameterisation. We demonstrate the application of this approach to a realistic and relevant industrial example for robustness analysis of the bumper location in a frontal crash simulation. The approach has the potential to considerably speed up the virtual product development process by allowing an intuitive and interactive simultaneous evaluation of many product designs.
