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.

Financial Times - Car prototyping moves from workshop to digital simulation

Carmakers spend a fortune on prototypes for new models. Such mock-ups are not seen by outsiders, unless photos dribble out on a motoring blog, but can each cost as much as $1m.

Now, however, these secret test bed vehicles could be on the endangered list as manufacturers shift towards digital simulation methods.

Design Engineering - Aerodynamic Optimization: Automotive Engineering’s Next Strategic Frontier

With the unprecedented demands on today’s vehicle engineering organizations, automakers face a daunting challenge to reach their next targets for aerodynamics drag using traditional tools and methods. Trial-and-error development using wind tunnel testing achieved a coefficient of drag of 0.3. Introducing digital simulation to sequentially improve designs brought CD down to 0.24 for today’s best performing cars. But most companies have the next target set to 0.2.

TopSpeed -Exa Corporation Unveils Ligier JS P3 Le Mans Prototype 3

The new LMP3 class is beginning to take shape, with several chassis manufacturers getting in on the action. The latest is Ligier along with simulation softwarecompany Exa Corporation, which introduced its new JS P3 LMP3-class racer this week at Le Mans.  Ligier adds its name to the roster of Ginetta and LAS Motorsport, who are among the manufacturers already committed to LMP3.

Sports Car Illustrated - Exa and Onroak Automotive unveil new LMP3 sports prototype

Exa Corporation and Onroak Automotive, unveiled an all-new LMP3 sports prototype racing car at Le Mans.  Ligier JS P3, the new LIGIER has been conceived to compete in the Automobile Club de l’Ouest’s new Le Mans Prototype 3 (LMP3) category which gives teams and drivers a new entry point into Le Mans-style endurance racing.The Ligier JS P3 was designed using Exa’s PowerFLOW simulation software to optimize its aerodynamics, as well as maximize cabin comfort and cool both the engine and brakes with new levels of efficiency.

Motorsport-Total.com - Onroak stellt neuen LMP3-Ligier vor

(Motorsport-Total.com) - Ginetta bekommt bald weitere Konkurrenz auf dem Markt für Fahrzeugeder neuen LMP3-Klasse. Zwei Tage nach der Vorstellung eines entsprechenden Projekts des Münchener Unternehmens Adess, hat nun Onroak ein fertig produziertes Auto in Le Mans präsentiert. Der neue Ligier JS P3, der unter anderem mit Hilfe der amerikanischen CFD-Spezialisten Exa entworfen wurde, soll in der kommenden Woche in ein intensives Testprogramm gehen.
