Ansys Fluent is a professional computational fluid dynamics (CFD) simulation software used by engineers to model flow, turbulence, heat transfer, and reactions for industrial applications. This sophisticated tool enables you to predict the performance of complex systems—from battery thermal management to aerospace aerodynamics—without the need for costly physical prototypes.
Key Features
- Native-GPU Solver: Accelerates simulation time significantly by running advanced physics models, including Surface-to-Surface (S2S) radiation and Volume of Fluid (VOF) multiphase flows, directly on graphics processors.
- Ansys Engineering Copilot: Uses an AI-driven assistant within the desktop interface to help you quickly locate technical support, set up complex parameters, and troubleshoot simulation errors in real-time.
- Watertight Meshing Workflow: Streamlines the preparation of "dirty" CAD geometries with task-based guided procedures, allowing you to generate high-quality meshes for complex assemblies in a fraction of the time.
- Automated Battery Workflows: Provides specialized physics models for simulating thermal runaway and electrochemical performance, helping engineers optimize cooling strategies for electric vehicle battery packs.
- Web-Based Interface: Allows remote access to lightweight simulation controls and monitoring tools via a browser, enabling you to pause, adjust, or check the status of solver calculations from any location.
Use Cases
Automotive engineers utilize this software to optimize the thermal efficiency of electric vehicle batteries and analyze external aerodynamics for drag reduction. It is also essential for aerospace teams designing turbine combustion systems and HVAC specialists modeling indoor airflow to ensure proper ventilation in large buildings.
Ansys Fluent delivers a distinct speed advantage through its expanded GPU capabilities and AI-assisted workflows, making it a superior choice for engineers who need to solve massive, high-fidelity models on Windows 10 and Windows 11 workstations.
Version 2025 R2 (25.2) — July 2025
- Integrated AI Assistant: Introduced the "Ansys Engineering Copilot," an AI-powered virtual assistant embedded directly within the Fluent interface to provide real-time support, documentation, and workflow guidance using AnsysGPT technology.
- GPU Solver Enhancements: Expanded GPU capabilities to include support for Electric Potential and Joule Heating, as well as enabling Conjugate Heat Transfer (CHT) compatibility for the Flamelet Generated Manifold (FGM) combustion model.
- Faster Radiation Modeling: Improved the performance of the Surface-to-Surface (S2S) radiation model on GPUs, achieving speed increases of 2x to 2.5x, and added new support for sliding mesh configurations in radiative heat exchange simulations.
- Advanced Multiphase on GPU: Upgraded the Volume of Fluid (VOF) GPU solver to support sliding meshes, multiple reference frames, non-Newtonian flows, and a new beta capability for coupled VOF and species transport.
- Battery Safety Modeling: Added a flexible Battery Thermal Abuse framework to simulate safety failure modes and thermal runaway scenarios with greater control.
- Expression Management: Fixed workflow bottlenecks by allowing users to rename expressions across the solver and UI with automatic dependency updates, eliminating the need to recreate links manually.
