ANSYS Fluent Features

Efficient and Flexible Workflow

Fluent is fully integrated into the ANSYS Workbench environment, a platform designed for efficient and flexible workflows, CAD associativity and powerful capabilities in geometry modeling and meshing. The built-in parameter manager makes it easy to rapidly explore multiple design options.

Built for Multiphysics

Gain deeper insight into the complex, often counterintuitive interactions caused by multiple physics such as fluid–structure interaction (FSI). ANSYS Fluent is fully integrated with ANSYS Workbench to provide full two-way interactivity with ANSYS Mechanical, ANSYS Maxwell and other simulation technologies.

Solve Complex Models with Confidence

ANSYS Fluent can solve your most sophisticated models for multiphase flows, chemical reaction and combustion. Even complicated viscous and turbulent, internal and external flows, flow-induced noise predictions, heat transfer with and without radiation can be modeled with ease.

Go Faster with High Performance Computing (HPC)

With HPC, ANSYS Fluent delivers CFD simulation solutions faster so that engineers and designers can make better decisions sooner in the design cycle. While ANSYS HPC provides linear scalability on systems with tens of thousands of processors, there is more to HPC than just the number of cores. ANSYS also optimizes processor architecture, algorithms for model partitioning, optimized communications and load balancing between processors to deliver results in breathtaking speed on a wide variety of simulation models.

Turbulence Modeling

ANSYS Fluent software places special emphasis on providing a wide range of turbulence models to capture the effects of turbulence accurately and efficiently. Several innovative models such as the Menter–Langtry γ–θ laminar–turbulent transition model™ are available only in Fluent.

Heat Transfer & Radiation

Fluent handles all types of radiative heat exchange in and between fluids and solids, from fully and semi-transparent to radiation, or opaque. You can choose from a variety of spectral models to account for wavelength dependencies in a simulation and to account for scattering effects.

Multiphase Flow

A complete suite of models capture the interplay between multiple fluid phases like gasses and liquids, dispersed particles and droplets, and free surfaces.

Reacting Flow

Whether simulating combustion design in gas turbines, automotive engines, or coal-fired furnaces, or assessing fire safety in and around buildings and other structures, ANSYS Fluent software provides a rich framework to model chemical reactions and combustion associated with fluid flow. ANSYS Fluent handles non-premixed, partially-premixed, or premixed combustion models to accurately predict parameters like the flame speed, flame location, and the post-flame temperature.

Acoustics

ANSYS Fluent computes the noise resulting from unsteady pressure fluctuations to solve acoustical simulations.

Fluid-Structure Interaction

Fluent models the effects of solid motion on fluid flow by coupling with ANSYS structural mechanics solutions through the Workbench unified user environment. Fluent users enjoy robust and accurate two-way FSI without the need to purchase, administer or configure third-party coupling and pre- and post-processing software.

Optimize Your Design - Automatically

Fluent’s shape optimization tools can automatically adjust the geometric parameters until your optimization goals are met. For example, aerodynamics of a car or aircraft wing and the optimized flow rate in nozzles and ducts.

Fluent’s ground-breaking adjoint solver modifies the mesh from within to see the effect of a recommended change. The adjoint solver provides recommendations to improve geometries that are difficult and expensive to get any other way.

Fluent for CATIA V5

This optional module fully integrates ANSYS Fluent into the CATIA V5 product lifecycle management (PLM) environment. It reduces the cycle time for computational fluid dynamics (CFD) analysis and enables a simulation-based design approach in which design, analysis and optimization happen all within the single workflow of the CATIA V5 PLM environment.
