Advantages of Virtual Prototyping• Virtual prototyping is necessary for maximum cost efficiency
• Test cycles are reduced and placed at an early phase of product development
• Optimization is introduced into virtual prototyping
• Robustness evaluation is the key methodology for safe, reliable and robust products
• The combination of optimization and robustness evaluation will lead to robust design optimization strategies

Robust Design Optimization (RDO) in Virtual Product DevelopmentWhat 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 enables you already in an early phase of prototyping: •to quantify risks
•to identify optimization potentials
•to adjust safety margins without limitation of input parameters
Thus, you can safely meet the requirements under consideration of all potentially effecting uncertainties and tolerances. Product performance and resource consumption will be optimized while reducing development time and costs.

optiSLang“Robust Design Optimierung - easy and flexible to use”
The software (stand-alone version or inside ANSYS Workbench) allows the automated generation of an interactive process chain with the modules for CAE-based sensitivity analysis, optimization and robustness evaluation with a minimum of required user input. Thus, efficient CAE-based Robust Design Optimization can be easily and flexibly integrated into daily procedures of virtual product development.

Pre- and Postprocessing with optiSLangEasy and safe to use!
The Pre-Processing Open architecture, user friendly parameter editor and one click solution for ANSYS workbench support simulation workflow setup.
Solving the RDO Task Easy and safe to use workflows with robust default settings allow the engineer to concentrate on the engineering part and let optiSLang find the optimal design.
Post Processing The interactive case sensitive multi- document post processing offers the most important plots as default.

When to use which optimization algorithm?optiSLang: easy and safe to use!
gradient-based algorithms• most efficient method if gradients are accurate enough• consider its restrictions like
local optima, only continuous variables
and no solver noise
Response Surface Method (RSM)• attractive method for a small set of continuous variables (<15)• adaptive RSM with default settings is the method of choice.
biologic algorithms• GA/ES/PS copy mechanisms of nature to improve individuals• method of choice if gradient or ARSM fails • very robust against numerical noise, non-linearities, number of variables,…
