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 7.0

  • Support of ANSYS Release 19.0
  • Adaptive MOP -  iterative metamodeling and datapoint refinement for more efficient parametric studies
  • Process&Script nodes now have the ability to bundle multiple designs up into a single job (design table submit)
  • For save and convenient usage of referenced files the filechoosers have access to central file registration of the project
  • Introduction of text based project format *.opx (Beta)
