If you want to design efficient light structures, the design requirements must be well defined. But often there is a lack of clarity about the exact loads that affect the design and which materials and production methods will be used. For example, efficient load determination can now be carried out quickly and now with the help of multi-body simulation in the design process. At the same time, weight and stress optimization simulations with the Finite Element Method are now also included in a simple way from the start. And importantly, this simulation technology can now be used for a much larger group of users, and designers in particular will benefit from this. Simulation-driven designs leads much faster to a designs that meets all requirements, is robust, optimal and reliable. It appears to be a very efficient method to develop complex new constructions faster.
