After attending the NAFEMS DACH 2016 in Bamberg, Germany, there is one thing pretty clear about simulation trends: Simulation is going to be EARLIER, SIMPLER and BIGGER!
EARLIER:
The later simulation tools are used in the product development process, the less the opportunities are to predict potential product pitfalls and failures. The later the change in the product, the more expensive they are! An example of a late change of the position of a car loudspeaker in the late product development process has been presented by Alfred Svobodnik. The estimated costs of this change were presented with roughly 1 mio. EUR total. Therefore, each serious company should integrate simulation tests (and of course experimental as well) very early in the product development process. Ideally even concept designers have tools available to investigate the effect of potential design changes on the overall product behavior.
SIMPLER:
Because simulation tools should be used earlier in the product development process, they need to be simpler to use as presented by Prof. Dr.-Ing. Sandro Wartzack. In the early development phase usually concept engineers define the design and functionality of a product. These engineers are often not trained for using simulation tools and thus are less likely to use them. Therefore there is a need for simulation tools that are integrated in their concept design environment and allow them the investigate evaluate the effect of design choices on the final product.
BIGGER:
Simulations tools are no more used to look at small parts individually; product live cycle management systems are facilitated to interconnect and link all product related data as presented by E. Niederauer (Siemens PLM). Simulation models of entire assemblies and mock ups are directly linked to CAD data and automatically run and update results based on design changes by the engineer allowing to assess the effect of design changes on a global product level. Computationally expensive simulations of entire assembled products are facilitated due to cloud services and High Performance Computing (HPC) leaving no doubt that time spent on model simplification will be reduced by facilitating increased computational resources able to handle enormous models discretisized with higher order 3D elements.
Additional aspects regarding model accuracy were discussed, clearly pointing out that models are going to be further advanced in complexity to be more "realistic". For Additive Manufacturing (AM) approaches have presented by the esi group to link Computational Fluid Dynamics (CFD) simulation to determine the effect of microscopic material melting and solidification with thermo-mechanical Finite Element (FE) simulations to predict the deformation of AM parts due to residual thermal stresses. However, such approaches are currently of limited value for industy since simulations times in the magnitude of weeks were experienced.
