Ansys Fluid Dynamics (CFD) Software

Fluid flow is often counter-intuitive. ANSYS CFD solutions enable you to successfully simulate fluid behaviour, including complex interactions between multiple physics, to optimise your products and processes before prototyping.

ANSYS offers a comprehensive fluid dynamics solution for modeling fluid flow and other related physical phenomena, including both general purpose software and focused products to address specific industry applications.

Unparalleled CFD capabilities from the CFX and FLUENT solvers, integrated within the ANSYS Workbench framework, enable you to design and optimise new fluid-related equipment and troubleshoot existing installations. Viscous and turbulent, internal and external flows can be calculated with ease, with an industry-leading set of turbulence models that can be extended to flow-induced noise predictions.

Bi-directional connections with all popular CAD systems enable seamless geometry import, automatic parametric studies and optimisation. The speed of ANSYS CFD simulations can be minimised through highly efficient parallel processing capabilities to exploit multiple core PCs and High Performance Computing (HPC). Combined with ANSYS Structural Mechanics or Electromagnetics solvers, ANSYS CFD software can undertake fluid-structure interaction (FSI) and other multiphysics simulations.

ANSYS develops the most comprehensive set of fluid dynamics simulation tools available for product and process design, development and research. With a common workflow and user environment, you can easily upgrade between appropriate solutions as your requirements evolve.

ANSYS CFD Enterprise includes all the computational fluid dynamics solvers that ANSYS has to offer, including Fluent, CFX, Polyflow, Forte and FENSAP-ICE, together with productivity modules such as ANSYS DesignXplorer, Simplorer Entry and ACT. For simulation-led design exploration, it also provides access to AIM structural, fluid dynamics and electromagnetic capabilities.

ANSYS CFD Premium comprises a comprehensive suite of fluid capabilities for the fastest, most accurate results across any fluid or multiphysics application, including Fluent and CFX solvers. ANSYS SpaceClaim is included with all ANSYS CFD products for rapid geometry building, editing, defeaturing and modifying.  

For Simulation-Led Design Exploration: ANSYS Discovery AIM is an integrated multiphysics solution for designer-focused simulation, including structural, fluid dynamics and electromagnetics capabilities.

Fluent software contains the broad, physical modelling capabilities needed to model flow, turbulence, heat transfer and reactions for industrial applications. These range from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing and from clean room design to wastewater treatment plants. Fluent spans an expansive range, including special models, with capabilities to model in-cylinder combustion, aero-acoustics, turbomachinery and multiphase systems. Fluent also offers highly scalable, high-performance computing (HPC) to help solve complex, large-model computational fluid dynamics (CFD) simulations quickly and cost-effectively. Fluent set a world supercomputing record by scaling to 172,000 cores.

New Fluent Experience: A whole new way to enjoy CFD simulations

Fluent already solves the toughest design challenges with well-validated results across the widest range of CFD and multiphysics applications. But today, engineers need to accomplish more, in less time and with less training than ever before. Introducing the New Fluent Experience, a whole new way to enjoy CFD simulations. Built on top of the proven Fluent solver, this new experience:

  • Provides a complete, single-window solution within Fluent
  • Streamlines the Fluent workflow for generating a mesh from imported CAD
  • Removes barriers for common tasks that frustrate users



A New Look

Fluent has a new look that’s easy on the eyes. Users can pick from several themes or chose the new, Japanese language localisation.

Task-Based Workflow

Fluent’s task-based workflow guides users through an organised simulation process that offers the most accurate results in less time. At each step in the process, the software provides the most relevant design options or defaults to a best-practice option. Benchmark data show that users complete the workflow with 70 percent fewer clicks and 50 percent less hands-on time.

Mosaic Meshing Technology

Fluent meshing now includes a unique patent-pending technology that delivers higher quality results at faster speeds. This Mosaic meshing technology uses a high-quality boundary layer mesh to automatically combine a variety of boundary layer meshes, for fast and accurate flow resolution. In a benchmark simulation of a Formula One wing, the Mosaic mesh had fewer, better quality cells, required 34 percent less memory and achieved a 47 percent faster solve time.

Speed and Simplicity

Thoughtful changes permeate every screen, every step, making simulation a joy. Users will encounter fewer clicks, simplified data entry, enabled drag and drop, embedded smart interactions and more.
