World-Class Fluids Analysis

The broad physical modeling capabilities of FLUENT software have been applied toindustrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to glass production, from blood flow to semiconductor
manufacturing, from clean room design to wastewater treatment plants. The ability of
the software to model in-cylinder engines, aeroacoustics, turbomachinery and multiphase systems has served to broaden its reach. Today, thousands of companies
throughout the world benefit from this important engineering design and analysis tool. Its extensive range of multiphysics capabilities makes it the most comprehensive
fluids simulation software available to the engineering analysis community.With its long-standing reputation of being user-friendly and robust, FLUENT softwaremakes it easy for new users to come up to productive speed. In conjunction with this,
ANSYS technical support offers comprehensive user training focused on making customers successful. Throughout the years, these important components Η compre-
hensive models, usability and technical support have combined to accelerate the
adoption of FLUENT fluid dynamics software across a broad spectrum of industries
worldwide. >

Grids, Numerics, Parallel Processing

At the core of any computational fluid dynamics calculation is a computational grid,
which is used to divide the solution domain into thousands, or millions, of elements in
which the problem variables are computed and stored. In FLUENT software, unstruc-
tured grid technology is used; this means that the grid can consist of elements in a vari-
ety of shapes, such as quadrilaterals and triangles for 2-D simulations and hexahedra,
tetrahedra, polyhedra, prisms and pyramids for 3-D simulations. These elements form
an interlocking network throughout the volume where the fluid flow analysis takes
place. Meshes can be created using automated controls in GAMBIT >
׮ software (thecompanion pre-processor for FLUENT) using other ANSYS or third-party meshing
products and, in the case of polyhedra, via automatic cell agglomeration directly within FLUENT software. In the commercial analysis arena, FLUENT technology is a leader in the number ofcomplex physical models offered on an unstructured grid. Sophisticated numerics and
robust solvers ― including a pressure-based coupled solver, a fully-segregated pres-
sure-based solver and two density-based solver formulations ― help ensure accurate
results for a nearly limitless range of flows. Mature parallel processing capabilities,
