The record

Purpose: Ansys optiSLang orchestrates and automates simulation toolchains and connects them to optimization algorithms for parametric design studies.
Process automation: It automates and orchestrates simulation workflows between heterogeneous CAx tools across an enterprise.
Optimization: It provides design optimization, robustness and reliability analysis, reduced-order modeling and model calibration.
Design exploration: Its capabilities include design of experiments and sensitivity analysis.
Integrations: The open ecosystem connects to more than 100 third-party CAE/CAD applications and in-house solutions.
Supported connectors: Integrations can use Ansys nodes, scripting, text-based interfaces or custom integrations, including CAD, CAE, desktop applications, repositories, databases and in-house solvers.
Minerva: optiSLang integrates with Ansys Minerva for workflow publishing and simulation process and data management.
AI capabilities: The optiSLang AI+ add-on provides machine-learning methods for sensitivity analysis, optimization and robust design.
2026 integrations: The 2026 R1 release adds or enhances connections for Rocky, FreeFlow, LS-OPT and Ansys SimAI.
Automation interfaces: The 2026 R1 release expands Python controls and supports cloud and HPC deployment workflows.
Operating systems: optiSLang and its extensions can be installed on Windows and Linux systems.
Enterprise limit: An enterprise license is required to build apps and conduct a much higher number of concurrent variations.
Security certifications: Ansys Cloud Direct has SOC 2, CSA STAR, ISO 27001 and ISO 27017 certifications, and Ansys maintains UK Cyber Essentials Plus and TISAX-certified environments.
Support and training: Ansys provides a Learning Hub for optiSLang that requires Ansys ID single sign-on.
