optiSLang robustness optimisation design tool

What would be your benefit if you knew to what extent your product development comes close to a reliable economic optimum? How robust is your design in reality?

optiSLang (The Structural Optimising Language) is one of the most efficient software tools for tasks regarding sensitivity analysis, multidisciplinary optimisation, reliability and robustness analysis as well as robust design optimisation.

Conducting a sensitivity analysis, multidisciplinary optimisation, robustness evaluation and reliability analysis with optiSLang enables you to:

optiSLang automatically identifies the relevant input and output parameters and quantifies the forecast quality with the help of the Coefficient of Prognosis (CoP) and the Metamodel of Optimal Prognosis (MOP). A predictable prognosis quality is the key to an efficient optimisation. Thus, a "no run too much" philosophy can be implemented to minimise solver calls. As a consequence, even optimisation tasks involving a large number of variables, scattering parameter as well as non-linear system behavior can be solved. optiSLang’s Best-Practice-Management automatically selects the appropriate algorithms, such as gradient methods, genetic algorithms, evolutionary strategies or Adaptive Response Surface Methods. Furthermore, all methods of optimization and stochastic analysis can be combined in regard to the particular task. optiSLang makes you ready to meet the full range of parametric studies to innovate and accelerate your virtual product development.

OptiSLang can be used at any stage of the development process. Optimisation and stochastic analysis can be performed as early as the product design. It is possible to design a product that meets all the requirements for sensitivity, reliability and durability.

Functionality of optiSLang

Existing simulation processes from any user-defined CAE program, pre and post processors can be connected through a graphical editor and are accessible to a parametric sensitivity study, optimisation or stochastic analysis. An important innovation of optiSLang are predefined interactive post processing flows. This allows even 'non-optimisation-specialists' to use successfully multidisciplinary optimisation and stochastic analysis. Gradient-based methods, genetic algorithms, evolutionary strategies and adaptive response surface methods can be used for optimisation in optiSLang.

For an optimal component construction have to be considered appropriately to avoid undesired scattering of product features. In optiSLang, variance or probability-based robustness evaluations of designs can be done. A large range of statistical parameters (e.g. variation, correlation, coefficient of determination and probabilities) is available for robustness analysis. Regarding reliability analysis, optiSLang offers efficient algorithms of stochastic analysis (FORM, several sampling methods) which can be combined with adaptive response surface methods. Different methods of optimisation and stochastic analysis can be combined with each other for tasks of robust design optimisation.

Innovation

A continous parameterisation of models is the key to succes for parametric design optimisation. Regarding parametric model creation, ANSYS Workbench offers excellent possibilities. With the help of an ANSYS Workbench plug-in, optiSLang can import directly all parameters from ANSYS Workbench and thus opens new opportunities for parametric optimisation. The vision of an optimisation of CAD parameters in a fully automatic CAE process starts to turn into reality.

optiSLang inside ANSYS Workbench - easy and flexible to use

ANSYS Workbench provides new opportunities to bring together automatically parametric CAD and CAE models making them available for virtual product development and optimisation. At the same time, in optiSLang, efficiency and automation level of RDO methods also for complex non-linear analysis models with many parameters of optimisation and stochastic variables, with design failures as well as solver noise have been decisively improved.


GUI optiSLang inside ANSYS Workbench

With optiSLang inside ANSYS Workbench, the automated generation of an interactive process chain using the CAE-based modules of sensitivity analysis, optimisation and robustness evaluation is possible with a minimum of user input. The software filters automatically the most important parameters and evaluates the prognosis quality of the response variation with the help of meta models. A best practice management chooses, accordingly to the RDO task, an optimisation strategy with the most fitting algorithms. The new graphical user interface supports this workflow approach.
