ANSYS optiSLang – CAE-Based Robust Design Optimization


ANSYS optiSLang – The optimal combination of parametric modeling and Robust Design Optimization (RDO)

ANSYS optiSLang combines leading simulation technology of ANSYS with optiSLang’s powerful capabilities in variation analysis and process automation. By building CAx-workflows for automatic design variation studies (sensitivity analysis, optimization and robustness evaluation), virtual product development becomes more efficient. Thus, better products can be developed in shorter time.

Modes of interoperability with ANSYS

The process integration and workflow building capabilities of optiSLang offer a distinguished support of ANSYS simulation tools. There exist 3 major ways to integrate ANSYS tools into optiSLang workflows and/or to use ANSYS’ powerful parametric modeling with optiSLang’s algorithms:

    • In ANSYS Workbench: the optiSLang Workbench plugin makes optiSLang technology available inside the powerful simulation platform
    • ANSYS Workbench node: The direct integration node enables the use of ANSYS Workbench projects in optiSLang workflows
  • Using graphical programming capabilities of optiSLang to combine ANSYS CAE with third party CAE/CAD tools for process automation and workflow building

Features of the Workbench Plugin

    • Reduction of the number of CAE solver runs by optiSLang’s minimalist philosophy
    • Automatic identification of important parameters during sensitivity analysis
    • Automatic buildup of best possible surrogate models (MOP)
    • Multidisciplinary and multiobjective optimization
    • Robustness evaluation
    • Insightful and efficient result post-processing module
    • Support of non-scalar responses (vectors, curves, signals, matrices)
    • Connection to database systems

Current Version 7.1

ANSYS optiSLang connecting simulation and optiSLang’s efficient algorithms and tools for workflows of variation analysis

Sensitivity Questions for Electric Machines and Answers via Meta-Models – Presentation at the 4th CADFEM ANSYS Simulation Conference Dublin 2017

Understand your design!

The technologies presented here enable the systematic variation of all relevant factors and therefore a comprehensive understanding of physical relationships is possible. The sensitivities determined speed optimizations  and support Reliability, Design for Six Sigma and the comparison of simulation and testing.

Typical application scenarios is next to the product improvement and the determination of parameters for numerical models such material, friction or damping as well as cost-effective maps for nonlinear components.The universal application – for both simple and complex tasks – that quality algorithms and high efficiency (“no run too much” – strategy) make at the same time safe handling optiSLang inside ANSYS a valuable tool for design engineers.

optiSLang and ANSYS

The integrated, tailored to parameter studies workflow in ANSYS Workbench is a very good basis for design studies and optimisations with optiSLang. By integrating ANSYS Workbench optiSLang combines intuitive handling with powerful methods. To succeed in not only the fast start, but also a more extensive range of tasks with high parameter numbers, nonlinearities or multidisciplinary multi-objective optimization.

Parametric sensitivity analysis

Which factors are relevant? How strong is the correlation between parameters? What power range can cover my design?
Help Parametric sensitivity analysis, important to distinguish from unimportant parameters to understand the relationships between design variables and results and to define its target for a powerful and viable design. About an automated design of experiments (design of experiments, DoE) is achieved a good ratio of performance and accuracy for the implementation of the sensitivity study: The predictive power of the determined correlations is quantified (Coefficient of prognosis) and allows so, with a minimal number of analyzes to considered design space to capture with a defined accuracy. The result monitoring of reliability helps to assess a large number of parameters
Multidisciplinary Optimization

Which design is best? How to treat competing goals?
Based on the relationships of the sensitivity analysis, the design can be optimized. This optimization takes into account simultaneously both more physical disciplines and multiple targets. For an electric motor which are for example the efficiency due to the magnetic field guide as well as the structural dynamic vibration due to the magnetic forces and the resulting sound pressure level. Available in optiSLang inside ANSYS optimization methods are automatically predefined reference to the task and can be easily overridden by the user via a traffic light system. They are suitable for special requirements as well as for classical optimization tasks.

Tolerance Analysis

How do variations have an impact on product performance? How secure my product will work under real conditions?
Variations in manufacturing processes, loads, material properties and geometries pull scatterings in the component behavior by itself. Numerical tolerance analyzes make it possible to check compliance of product characteristics in such situations. This well-established in terms of geometric properties technique is increasingly being used for physical properties. The simulation of virtual prototypes is an inexpensive way to examine the robustness of a design and to verify the safety of a product under real operating conditions.
