Realize Your Product PromiseSystems and Multiphysics Analysis

Your organization faces complex (and sometimescompeting) pressures like never before. Youneed to create the next must-have product.That product must be rst to market. It has to be

aordable for your customers, yet priced so yourorganization turns a prot. And, of course, it hasto work as advertised.

The challenges dont stop there: You have tomeet all of these requirements in an environmentin which product lifecycles are shrinking,global competition is increasing, and customerexpectations are higher than ever.

Engineering products the way you have for thelast 20 years is simply no longer an option if youexpect to survive much less thrive in todayshyper-competitive marketplace. Simulationhas revolutionized product development overthe past decades by minimizing costly physicaltesting and accelerating time to market inevery industry around the world. But for manycompanies, that simulation has largely focusedon components or subsystems. Technologyadvancements in engineering simulationsoftware now bring a total systems approachto product design and engineering.

With a robust technology platform and industry-leading multiphysics, ANSYS moves your

engineering team beyond localized areas of design and simulates the system as a whole.

ANSYS delivers technology that enables you to study how products will behavein the real world, where multiple forces interact. Simulation-Driven Product

Successful product development requires numerous

things: talented systems-level thinkers, complex

modeling, a robust simulation process, and enough com-

puting power to handle it all. ANSYS allows us to try it

before we build it. We can combine multiple scientic and

engineering disciplines earlier in the process, creating an

environment in which development can evolve creatively

and economically.

Product Complexity Drives Systems Approach

Many organizations have responded to increasedcompetition by designing smart products.

Such next-generation devices ranging fromcellular phones to automobiles to wind turbines adapt to their environment or user. Since theseproducts are relatively new, you cant rely onhistorical real-world testing. So systems-levelsimulation plays a much larger and important role in product engineering.

Using ANSYS engineering simulation softwarethroughout the entire development cycle enablesyou to predict with condence how your productswill behave and how manufacturing processeswill operate in a real-world environment.

In the early development phase, our tools canhelp your cross-functional engineering organi-zation predict system-level performance, thenwork on improvements in individual componentsor subsystems, as well as their interactions withone another, especially with multiple physics.You then continually and rapidly ne-tune theentire product system in a virtual environmentuntil it is ready for physical assembly andtesting. This accelerates the developmentprocess and increases performance success

when products are launched.

Traditionally, simulation has been used only inthe validation stages. But as products becomeincreasingly complicated, leading companiesare using ANSYS simulation earlier in theprocess to ensure that the products createdlive up to their promise.

A perplexing problem for mobile phone users isdropped calls. EPCOS leveraged our suite tosimulate the transient dynamic response of aninnovative RF-MEMS switch for improving cellphone signal strength. The approach accountedfor uid, electrostatic and mechanical eects ina single model, providing fast turnaround forrapidly changing cell phone requirements.

A team from Politecnico di Milano is applyingsystems modeling to help doctors make surgicaldecisions for children born with a heart conditionin which only one ventricle functions. Multidomainmodeling becomes critical when consideringbiouid dynamics in reconstructive pediatric cardiacsurgery; a systems approach to predict the results ofsurgery is both appropriate and appealing. Because

there is a wide spectrum of possible surgicaltreatments to repair a complex heart defect, patient-specic multidomain modeling can help considerablyin choosing the best treatment to ensure optimalblood ow for the patient.

Few product systems are aected by just onephysical force. In the real world, productsundergo a wide range of thermal, mechanical,electromagnetic and uidic forces. Consequently,

any system-level assessment must include multi-physics considerations to accurately predictperformance. The implications to your businessare enormous. Warranty expenses and brandreputation run parallel, in part, to how well youunderstand at a deep level the physical stressesthat products will be subjected to and howthey will respond.

Many product recalls occur when individualcomponents do not perform as expected whenthey are brought together. A tablet computermanufacturer may not plan for the signicantthermal eects that occur when dozens ofdisparate electrical components are combined.The accuracy of a GPS device may be aectedby electromagnetic interference from nearbycommunication systems, by the properties of thecomposite materials in its case, or even by theway consumers mount the device in their cars.If individual components are simulated as partof a system from the earliest design stage, theseaws can be identied and addressed beforecostly physical assembly and testing occurs and well before product launch and recall.

Greater than the Sum of its Parts

Component-level simulation has generated incredible returns. Imagine what your business

can achieve by analyzing subsystems together in a virtual world.

Voith Turbo reduces the cost of developing quiettrain fans with ANSYS software, simulating acomplete railcar cooling system. The 50-million-element mesh balanced the need for critical detailswith available resources.

As advanced medical devices become more complex,simulation can maintain functionality while addressingsafety concerns. In an open MRI system, the detailsof the radio-frequency coils, a human body model,and the large volume of the exam room must all beincluded in sucient delity in a simulation model todetermine the resulting eld accurately. Our software

is ideally suited to this task.

A Single Resource for Technology Leadership

With the broadest and deepest multiphysicscapabilities available today, ANSYS is uniquely

qualied to support your business as it movestoward system-level simulation. Every dayand in every industry, leading companies areapplying software from ANSYS to solve theirstructural, thermal, electromagnetic and uidicchallenges as well as to consider the eectsof multiple physics on a single componentor coupled system.

ANSYS brings industry-standard multiphysicscapabilities combined with our expertise indata and process management, reduced-order

modeling and cosimulation, and applicationintegration for system-level analysis via asingle, easy-to-use technology platform.

Engineers at critical component suppliers canalso leverage ANSYS tools the acknowledgedindustry standard for engineering simulation to maximize the contribution of their own partsto overall system performance.

Isolated product failures can damage anorganization in the form of reputation, sales,stock price, warranty claims, legal costs andcredit rating. Product integrity is a critical issuein complex systems such as cars and airplanes,in which electronic and electromechanicalcomponents are developed by multiple vendors,increasing the opportunity for crosstalk andelectromagnetic interference, or EMI.

ANSYS software plays a critical role, giving us the

ability to run full-stage simulations while keeping pace

with the design process. This provides insights that are

not available when simulating individual components.

Engineers can gain a much better understanding

of the interaction between the compressor wheel and

the diuser when simulating the entire system.

Cameron used ANSYS multiphysics technology todevelop a new line of check valves for the petro-chemical industry. The engineering team coupled uid

dynamics and mechanical analyses with optimizationtools to reach record performance.

What was acceptable yesterday was simulating one

single component, but it becomes more important

today to simulate the full assembly, because each

part interacts.

As multiphysics and advanced modeling methods become more advanced, simulation-based

engineering and science will be indispensable in meeting the technological challenges of the

21st century. The process will not be simulation as usual for narrow studies of individual

parts and assemblies, but it will be focused on complex, interrelated engineering systems and

analysis results that meet specied standards of precision and reliability.

We look at hundreds to thousands of individual components, analyzed together as a

unit: aircraft hydraulic and fuel systems that have to y for 30 to 50 years and meet

certication requirements. We made a conscious decision to achieve greater value

from our hardware and software investments. We have signicantly increased our

throughput, and we are using all the available technologies at Parker Aerospace toexpedite design decisions using ANSYS.

In the past, CAE methods struggled to be simultaneously

fast and accurate, slowing the integration of these

techniques into the development process of complex

systems. I think that Workbench represents a milestone

in overcoming these problems and allowing simulation

to be perceived as a standard and required activity

in complex product development.

Real-World Applications

Automotive

Today, automotive engineers are at the forefrontof applying system-level simulation, developing

innovative powertrain systems for hybrid andelectric vehicles. These systems bring togethermany advanced components from batteriesto power electronics to traction motors eachhighly complex in its own right. Leveraging oursoftware, developers optimize individualcomponents along with the interactions andinterdependencies of the isolated parts.

By applying ANSYS software at the systemlevel, automotive engineers are able to evaluatehundreds of design alternatives within multipledomains, conduct numerous what-if studies,predict vehicle behavior in real-life drivingscenarios, and optimize nal designs in a rapid,cost-eective manner.

Energy

In the energy industry, designers of oshorewind turbines leverage ANSYS software toanalyze the eects of wind, waves, oceancurrents and other forces. They study complexsoilstructure interactions at the seabed level.

Understanding and addressing all load sourcesand their interactions is essential in verifyingthe reliability of these turbines and ensuringthe safe, cost-eective operation of large-scaleoshore wind farms. We provide accuratemultiphysics modeling capabilities to supportthis advanced application.

Manufacturing

Industrial manufacturers also apply our solutionsto understand and optimize complex inter-actions during multi-step production processes.For example, a steel manufacturer recentlyused ANSYS software to design innovative newrefractory equipment, which meant modeling acomplex process ow as liquid steel comes fromthe blast furnace, moves through a channel, andis continuously cast via molds. This sophisticatedsystem-level simulation incorporated multiphaseows, liquid metal, entrapped air, and inclusionsand other process irregularities. Only ANSYSsoftware was able to manage the complexitiesof this system-level modeling challenge.

The coupled thermal and electro-magnetic tools provide us with insight

into interactions between pacemakers

and MRI scanners, which is a complex

problem. Using simulation allows us to

really understand the problem, so that

we can mitigate the hazards.

Mariya LazebnikSenior ScientistMedtronic

A residential high-rise in London is the rst major building to incorporate windturbines into its structure. Rambll Denmark applied our tools in designing itbecause of the softwares ability to eciently handle large dierences in scale.The computational domain extended for several kilometers, as the simulation hadto incorporate the eects of nearby buildings; at the same time, the mesh neededto resolve ne details in the area of the turbine.

In the consumer products sector, yoomi used our technology to develop a babybottle/milk warmer. The multiphase simulation evaluated many design candidates,enabling yoomi to deliver its product two years ahead of schedule.

Understanding how the whole system works was critical to developing an optimized

design in minimal time. We performed a series of design studies using the simulation

software and utilized the results to build a simpler analytical model to crunch through

thousands of possible geometric alternatives.
