Fluent software contains the broad, physical modeling 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.

All users can get great CFD simulation results with Fluent
With the new Fluent experience, novice or expert users can run fluids simulations, in less time and with less training than ever before. Easy-to-use, task-based meshing workflows and Mosaic technology — paired with Fluent’s proven solver — deliver superior results.

  • 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.

In this tutorial you will learn to the difference between steady and transient simulation using ANSYS CFX. First, we will create the geometry and then we will generate the mesh using a structured mesh in Ansys Meshing.

The NACA four-digit wing sections define the profile by:
First digit describing maximum camber as percentage of the chord.
Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.

OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organisations.

We share the same tutorial using ANSYS Fluent.
