The product design process results frequently from different disciplines. The product characteristics have to be tested under several conditions to satisfy all requirements and specifications. Rebuilding this development process virtually, OptiY® provides a multidisciplinary analysis and optimization of several simulation models. Each model corresponds an experiment (e.g. thermal, fatigue, dynamics, etc). For all models, the same design parameters and different evaluation goals are used, because all experiments base on the same design parameters, but different test criteria and constraints. Interacting between different experiments is also possible.
