In their own words
Ansys optiSLang
Ansys optiSLang automates simulation workflows and connects them to optimization methods for parametric design studies. It coordinates processes between heterogeneous CAx tools across an enterprise. Its capabilities include design optimization, robustness and reliability analysis, reduced-order modeling, model calibration, design of experiments and sensitivity analysis. The open ecosystem connects with more than 100 third-party CAE/CAD applications and in-house solutions through Ansys nodes, scripting, text interfaces or custom integrations. It integrates with Ansys Minerva for workflow publishing and simulation process and data management. The optiSLang AI+ add-on provides machine-learning methods for sensitivity analysis, optimization and robust design. Windows and Linux installations are supported, alongside web and self-hosted platforms. The 2026 R1 release expands Python controls and support for cloud and HPC deployment workflows, and adds or enhances connections for Rocky, FreeFlow, LS-OPT and Ansys SimAI. Pricing is available on request and a 30-day trial is listed. An enterprise license is required to build apps and conduct a much higher number of concurrent variations.
