Ansys optiSLang — Variation Analysis & Robust Design Optimization

Ansys optiSLang is an enterprise software for simulation process integration and multidisciplinary design optimization (PIDO). It automates the R&D workflow by connecting disparate simulation tools and applying advanced algorithms to identify the most robust and high-performing design variations.

• Automated Process Integration: Connect Ansys solvers (Fluent, Mechanical, Maxwell) and third-party tools into a seamless, automated simulation chain to eliminate manual data handling.
• Metamodeling (Metamodel of Optimal Prognosis): Utilize AI-driven algorithms to create high-fidelity surrogate models (ROMs), allowing for thousands of design evaluations in seconds.
• Sensitivity & Trend Analysis: Automatically identify which design parameters (CAD dimensions, material properties, loads) have the greatest impact on product performance.

Technical Performance & Analytics

• Design of Experiments (DoE): Efficiently sample the design space using advanced filters to minimize the number of simulation runs while maximizing data insight.
• Robustness Evaluation: Go beyond simple optimization by accounting for real-world tolerances and scatter, ensuring designs perform reliably under varying conditions.
• Signal Processing Integration: Analyze complex time-series data and frequency responses directly within the optimization loop for NVH and electronics cooling applications.

Why Engineers Choose Ansys optiSLang?

optiSLang transforms "Trial and Error" into a data-driven engineering process. By quantifying the reliability and sensitivity of a design, organizations can reduce physical prototyping costs and accelerate the time-to-market for complex, multi-physics systems.

Key Optimization Workflows

• Multi-Objective Optimization: Balance competing goals, such as reducing weight while increasing structural stiffness, using Pareto-front visualizations.
• Reliability-Based Design (RDO): Quantify the probability of failure by simulating stochastic variations in manufacturing and operational environments.
• Calibration & Correlation: Automatically tune simulation parameters to match physical test data, ensuring highly accurate virtual models.

Frequently Asked Questions

What is Ansys optiSLang?

Ansys optiSLang is a Process Integration and Design Optimisation (PIDO) platform that uses AI-driven metamodeling to automate sensitivity analysis, Design of Experiments (DoE), and robust design optimisation enabling engineers to identify optimal design variations significantly faster than manual parameter studies.

What is PIDO (Process Integration and Design Optimisation) software?

PIDO software automates the connection between simulation solvers and optimisation algorithms, enabling systematic exploration of design parameter spaces to achieve performance targets with minimal manual setup replacing time-consuming trial-and-error with automated, data-driven optimisation.

How does Ansys optiSLang use AI for design optimisation?

optiSLang builds surrogate models (metamodels) from simulation data using machine learning. These metamodels allow engineers to rapidly explore large design spaces and identify optimal configurations without running a full simulation for every parameter combination reducing compute time significantly.
