Multidisciplinary Analysis and Optimization

Specifications

OptiY® is an open and multidisciplinary design environment providing most modern optimization strategies and state of the art probabilistic algorithms for uncertainty, reliability, robustness, sensitivity analysis, fatigue life prediction, data-mining and meta-modeling. The simulation model can be considered as black box with inputs and outputs. Within, it is an open platform for different kind of model classes. The adaptation to a special simulation environment takes place by a suitable interface. Collaborating different simulation systems is possible as networks, finite-element-method, rigid body dynamics, also material test bench as control optimization for drives.
