The ANSYS Fluent package combines deep physics andyears of simulation development expertise to solveCFD challenges right out of the box.

Trust ANSYS uid dynamics to deliver accurate insight

into your products, fast.

There are huge numbers of engineering

applications that can benet from computationaluid dynamics simulation. Whether you analyzecommonplace uid ow and heat transfer or workwith complex transient reacting ows, ANSYSFluent software should be an integral part of yourproduct design and optimization process.

A fully featured uid dynamics solution formodeling ow and other related physicalphenomena, Fluent oers unparalleled analysiscapabilities. It provides all the tools neededto design and optimize new equipment and totroubleshoot existing installations. The versatiletechnology oers insight into how a productdesign will behave in the real world, all beforea single prototype is built. Fluents capabilitiesare developed by world-renowned experts andsupported by extremely experienced engineers so you can have condence in the solution as

you develop higher quality products faster,decrease time to market, reduce risk andincrease innovation.

Fast, Accurate Solutions Glean ProductBehavior Insight

Even amid global competitive pressures andcomplex requirements, you cannot aord tosacrice accuracy. We understand this tenet,delivering software that provides accurate insight

into your products behavior quickly andeciently.

To provide high productivity, the ANSYSWorkbench platform directly couples with yourCAD software and automatically extracts andmeshes uid volumes. You control this easy-to-perform operation via a small set of parameters;the yield is the high-quality meshes critical forboth accurate and fast CFD simulation.In developing a

revolutionary fan concept,

the Dyson team investigated

200 diferent design

iterations using simulation,which was 10 times the

number that would have

been possible had physical

prototyping been the

primary design tool.

Our CFD package includes solvers that accuratelysimulate behavior of the broad range of ows thatengineers encounter daily from Newtonian tonon-Newtonian, from single-phase to multi-phase,and from subsonic to hypersonic. Each solver ishighly robust, well tested, validated and optimizedfor fast simulation time. Time tested and part ofa single environment, the highly ecient solversdeliver both accuracy and speed.

For deeper insight such as making informeddecisions about small adjustments that yield large

performance improvements you can increasethe granularity of the analysis. Such improvedresolution requires more computational resourcesand parallel computing. Fluent has a record ofoutstanding parallel scalability, ranging from twoprocessors to thousands, giving you high-delityresults in the shortest possible time.

Optimizing your product requires evaluatinga large number of designs. Your toolkit shouldinclude capabilities for design explorationand optimization studies in a fast, easy-to-useand robust manner which provides betterinsight into product performance. Capabilitieswithin ANSYS Workbench enable ecient,fully automated optimization (or design ofexperiments) for tens or hundreds of designpoints; the technology can evaluate many designpoints concurrently. Workbench makes the processeasy by controlling the execution, results data and

le management for each set of design points.

Addressing the Complex Physicsof a Complete System

Over the years, products have become extremelycomplex. So too have your uid dynamicsproblems: Systems with moving parts (such aspistons and valves) require transient analysis;

systems with phase changes due to heating orcooling liquids (for example, heat exchangers)require accurate, multi-phase capabilities; andsystems with challenging multiphysics phenomena(such as uidstructure interaction) call for easy-to-use, accurate advanced capabilities.

To gain more insight into product behavior, youneed to consider the full range of physics presentin the system you are designing. Fluent oersstate-of-the-art advanced capabilities to modellaminar and turbulent ows as well as more-complex physics including multiphase ows,

chemical reactions, radiation and particulatedynamics. You can be condent that Fluent willaccurately predict product behavior because allmodels are thoroughly tested and validated.

For best-in-class products, engineers can nolonger rely on analyzing one type of physics (uids,structural or electromagnetics). Instead, you muststudy all physics along with their interactions.

You can seamlessly couple Fluent with ANSYSstructural mechanics or electromagnetics

simulation tools to gain insight into the entire

system. For example, you can study how theuids system deforms the structure that containsit, or how the heat generated by an electroniccomponent aects uids temperature.

The Right Investment in the Right Technology

Simulation R&D outlays in terms of time, eortand dollars must provide a positive nancialreturn, now and over the long term. Fluent is asafe CFD investment. The technology is the toolof choice for many of the worlds largest andmost innovative companies. Its reliability is wellvalidated by academic researchers, independentorganizations, technology partners and clients.

In this two-way FSI solu-tion of transient blood

ow through a three-leaf mitral valve, bloodow is represented withnon-Newtonian uid,and biological tissue ismodeled with anisotropichyperelastic materialproperties. The solutionincludes 3-D remeshingof the uid domain,nonlinear materials

and contact.

Because of our commitment to quality assurance,customers use our CFD tools with full condence.Bechtel National applies Fluent to convert nuclearwaste into a stable, glass-like material for storage.Multiphase tools accurately predict the mixing abilityof vessels in which the waste is treated.

For HEV/EV development, such as cell temperaturedistribution and ow eld in a battery pack, theANSYS integrated platform enables researchers tosimultaneously evaluate individual components andsubsystems under various physical conditions uids, structural stress, thermal, electromechanicsand more as well as the interactions between themat the system level.

Airplane stall predictioncan pose a dicultproblem, even forsophisticated CFD tools.In designing a roadableaircraft, Terrafugiadeveloped a virtual blademodeler that plugged into Fluent and createdadditional capabilitiesto model the aircraftspropeller. This way,the aircraft could bereshaped as required.

Choosing the right CFD software also meanschoosing the right software company, one in whichdevelopers and support teams have the expertiseand knowledge to create tools that enable robustand accurate solutions. One of the worlds largestpools of simulation experts, the ANSYS teamserves a comprehensive range of industriesand applications. We provide the assistanceand training needed to ensure success in anysimulation challenge you face.

Some applications require the use of softwareproducts that have traceable and well-established

quality assurance processes. ANSYS has a deepand longstanding commitment to quality. Wewere the rst organization to receive ISO 9001certication for design analysis software, and wemaintain this certication year after year.

With a goal of extending o-highway vehicle lter, engine and component life, Donaldson Company leveraged Fluent to develop andoptimize an air pre-cleaner. Physical tests showed that, as predicted by the simulation, the pre-cleaner separates 99 percent ofcontaminants 20 microns and larger contributing greatly to air lter service life.
