Key Features
Where Physics, Performance, and Precision Converge
Explore a comprehensive suite of Fluent capabilities from pre-processing to solving to post-processing.
Pre-Processing
Advanced Meshing Technologies
Fluent’s meshing solutions streamline workflow and enhance accuracy with:
Task-Based, Automated Meshing
Automate the meshing process with task-based workflows that optimize mesh quality and reduce manual setup.Mosaic Meshing
This patented technology connects polyhedral prism boundary elements to elements to either polyhedral or hexahedral elements in bulk regions, delivering highly accurate flow resolutions without excessive mesh density and avoiding tetrahedral transition elements.Rapid Octree Meshing
Ideal for large, complex geometries, this top-down approach rapidly generates high-quality meshes from initial CAD, making it indispensable for high-resolution and multi-scale simulations.Wrap Meshing
Efficiently handles surface geometry in complex CAD models, speeding up setup time for fluid simulations.
Pre-Processing
Customizable Materials Database
Access a vast, customizable materials database to quickly select properties suited for your application, including real fluids (steam, refrigerants, and cryogenics) and support for custom material definitions. Fluent’s materials library ensures accuracy from the start, especially in multiphase, chemical, and thermal simulations.
Solving
Density-Based and Pressure-Based Solvers
Ansys Fluent offers specialized solvers to tackle a wide range of flow conditions. Whether modeling high-speed compressible flows or low-speed fluid dynamics, Fluent ensures accurate and efficient simulations for any application.
Density-Based Solver
Suitable for high-speed and highly compressible flows, including supersonic and hypersonic regimes. Common applications:Aerospace: Hypersonic vehicles, supersonic jets, rocket nozzles.; Combustion: Detonations, high-speed reactive flows.Pressure-Based Solver
Efficiently handles low-speed compressible and incompressible flows, from subsonic to low supersonic regimes. Common applications — HVAC and Building Systems: Airflow in ventilation and cooling systems; Automotive and Industrial Equipment: External aerodynamics, pumps, fans, and heat exchangers.
Solving
Turbulence Models
Fluent delivers cutting-edge turbulence modeling capabilities, including Reynolds Averaged Navier-Stokes (RANS) models, such as k-epsilon and k-omega models, as well as the Reynolds stress model for highly anisotropic flows. Advanced scale-resolving turbulence models are also available: large eddy simulation (LES), detached eddy simulation (DES) and scale-adaptive simulation (SAS). Fluent also offers hybrid approaches, with various flavors of hybrid RANS-LES modeling. In addition, innovative transition models accurately predict the flow in which the boundary layer transitions from laminar to turbulent regime.
Post-Processing
High-Fidelity Ray Tracing for Enhanced Visualization
Use ray tracing to generate high-resolution, photorealistic visualizations of simulation results. Ray tracing enhances presentations, enabling stakeholders to visualize complex flow patterns, thermal gradients, and material properties clearly.
Web-Based UI for Remote Access
The Fluent web interface allows you to access Fluent on the web and view your simulation results in real time as calculations are running. Perform pre-processing to solving to post processing within a single, modernized user interface.
