Digital Engineering -Simulation: Störgeräusche erkennen und beseitigen

Die Exa Corporation, ein Lösungsanbieter von Software für die Produktentwicklung, hat heute sein zum Patent angemeldetes FIND Modul (Flow-Induced Noise Detection = strömungsbasierte Geräuschortung) als Teil von Exa PowerACOUSTICS vorgestellt. Diese integrierte Lösung stellt einen entscheidenden Fortschritt innerhalb von Exas existierenden aeroakustischen Simulationsverfahren auf der Basis der numerischen Strömungsmechanik dar (Computational Fluid Dynamics, CFD), weil FIND den Ursprung von Geräuschen aufspürt, die von einer Luftströmung transportiert werden.

webauto.de - FIND findet Geräuschquellen

Geräuschquellen innerhalb und außerhalb eines neuen Fahrzeugs zu minimieren, ist eine extrem aufwendige Angelegenheit. Eine Verbesserung an der einen Stelle kann eine drastischen Verschlechterung an einer anderen bewirken. Jetzt hat die Exa Corporation eine Software entwickelt, die den Ursprung von Geräuschen aufspürt und so ermöglicht, sie zu beseitigen. Beim neuen 7er BMW und beim Rolls-Royce Phantom war die "FIND Modul" genannte Neuheit schon im Einsatz.

Exa Announces Breakthrough in Software for Detection and Elimination of Unwanted Noise Through Simulation

Exa® Corporation, a global innovator of simulation software for product engineering, today revealed its patent-pending FIND (Flow-Induced Noise Detection) capability within Exa PowerACOUSTICS. This integrated solution represents a critical advancement for Exa's existing aeroacoustic computational fluid dynamics (CFD) simulations by clearly pinpointing the origins of airflow-induced noise.

Hard Working Trucks - Virtual aerodynamics test blows away wind tunnels

Your truck’s aerodynamics matter. Not just for fuel economy, but for handling and noise reduction.

Enter Exa Corporation. This behind-the-scenes industry giant, based in Burlington, Ma., uses MIT developed software to conduct simulated aerodynamic tests for nearly every automaker on the planet.

HPC Wire - Accelerating HPC in Formula One

The Formula One racing community has embraced HPC as an essential part of its workflow to build ever-speedier race cars, but suggestions that CFD should obviate the need for wind tunnel testing continue to draw heated commentary. One of the aerodynamics software vendors that supports this move is Exa Corporation. The Burlington, Mass.-headquartered company serves the international automotive and transportation markets and maintains a global customer roster that includes NASA, BMW, Ford, Jaguar and Tesla, and more than one F1 racing team

Automotive World - Exa sponsors Fuel Economy Detroit

Exa has been confirmed as a co-sponsor of Fuel Economy Detroit, which will take place in Dearborn, Michigan on 17 March 2016. The conference will bring together the stakeholders tasked with creating the fuel-efficient cars of tomorrow.

Exa will also be showcasing at the event. Please visit Stand 1 on the day and Exa experts will be on hand to assist you with any questions you may have.

AutoBild.es -Los prototipos digitales reducen el coste de nuevos modelos

Las nuevas tecnologías que utilizan las marcas de automóviles para fabricar los ‘prototipos digitales’, están ayudándolas a ahorrar mucho dinero, y es que, realizar las pruebas de choque, la aerodinámica, o poder medir el consumo de combustible mediante una simulación virtual reduce el tiempo de desarrollo de un nuevo modelo y ahorra muchos millones de euros.

Automotive Design and Production - Follow the Bouncing (CFD) Balls

While it may seem as though this picture shows a Chrysler 200 being surrounded by some sort of colorful bouncing balls, an automotive analog to one of those ball pools found in fast food joints. . . in point of fact, this is an aerodynamic simulation of the sedan being run in PowerFlow, a software package from Exa Corp. that allows designers and engineers to see things on a vehicle that are not readily apparent through wind tunnel testing (e.g., airflow within wheel wells).

OEM Off-Highway - Easier accessibility in the cloud

Today, the cloud has become a ubiquitous term for the way in which we store just about everything—photos, music, documents. It enables us to store our information in a remote location, and then access that information from anywhere at anytime. The cloud has also made it easier to share information, becoming a key tool in many organizations for project collaboration.

Engineering.com - Reducing Drag Coefficient by Over 20 Percent with Simulation

Engineers at Fiat Chrysler Automobiles (FCA) used simulation-driven design to reduce the drag coefficient of the Chrysler 200 from 0.342, according to allpar.com, to 0.27.

This more than 20 percent improvement in aerodynamics was made possible with simulation iterations powered by Exa Corporation’s PowerFLOW.

Press Release - Exa Helps Streamline Chrysler 200

Exa Corporation (NASDAQ:EXA), a leading innovator of simulation software for product engineering, has revealed that its PowerFLOW® simulation tool was used to test and develop the aerodynamic characteristics of the Chrysler 200, helping FCA US LLC achieve a 0.27 drag co-efficient through a large number of design iteration simulations that would have been impractical and costly to do in a wind tunnel.

Photo Release -- Mitsubishi Reveals Exa Corporation's Aerodynamic Simulations Behind Its Record-Breaking Electric Racecar Success

BURLINGTON, Mass. and YOKOHAMA, Japan, Sept. 1, 2015 (GLOBE NEWSWIRE) -- Exa Corporation (Nasdaq:EXA), a global innovator of simulation software for product engineering, recently announced its customer, Mitsubishi Motors Corporation's (MMC), revealed PowerFLOW® helped them achieve a remarkable 25 percent downforce improvement for its record-breaking electric racecar, the MiEV Evolution III.

Desktop Engineering - The Sky is the Limit for Cloud Computing

If you’ve ever submitted a batch job to a remote computer across a building or across the country, you’ve worked with a variation of cloud computing. Shared hardware has made sense for more than 50 years and it still does; we have moved well past the why and onto exploring the how, but sometimes the “how” can seem dull. Is the decision now more like choosing between cable or dish TV? Are cloud resources just repackaging or is there really value added?

SAE International - Advanced Simulation Aids Heavy-Truck Aerodynamics

There is more pressure than ever on heavy-truck engineers to find and create significant improvements in fuel economy and reduce tailpipe greenhouse gas (GHG) emissions. This is being driven primarily by two factors. First, customers are looking for ways to improve their business model by reducing fuel consumption. Diesel fuel prices in the past few years have been volatile, ranging from $2.931/gal (Sept. 6, 2010) up to $4.159 (Feb. 25, 2013) and back down to $2.561 (Aug. 24, 2015), according to U.S.

Electronicsweekly.com - Software takes sports car design to new level

Is this the first sports car to be designed in software like a PCB or chip?  

The Ligier JS P3 sports prototype racing car was designed using simulation software to optimise its aerodynamics an for thermal design of the engine and brakes.

US-based Exa is the EDA company behind the PowerFLOW simulation software.  

The software is used by many major passenger-car manufacturers around the world, but French sports car maker Onroak Automotive has taken this to a new level with its simulation of the design of the Ligier JS P3 racer.
