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 regression functions (MOP)
  • Multidisciplinary and multiobjective optimization
  • Robustness evaluation
  • Insightful and efficient result post-processing module
  • Support of non-scalar responses (vectors, curves, signals, matrices)

Current Version 6.2.0

  • Support of ANSYS Release 18.2
  • Many improvements of MS Excel integration node for an easier parametrization and execution
  • optiSLang now allows remote control and monitoring of projects which run in batch and cluster environments
  • ANSYS optiSLang now includes project placeholder, PDM send&receive and all other features to support PLM/PDM connectivity
  • Beta option: Adaptive MOP - iterative metamodeling and datapoint refinement for more efficient parametric studies
