EPA to Use ANSYS FORTE to Prove CAFE Standards Are Achievable

Are the upcoming Corporate Average Fuel Economy (CAFE) standards realistic or achievable? It’s something EPA has to first find out for itself. To do that, the Agency is using ANSYS FORTÉ, a package for simulating combustion engine activities.

According to the announcement released by ANSYS today, EPA plans to use FORTÉ software “to model in-cylinder combustion to develop an advanced test engine that will demonstrate fuel-saving and emissions-reducing technologies.”

ANSYS FORTÉ used to be a product of Reaction Design, based on San Diego, California. The product became part of the ANSYS portfolio when Reaction Design was acquired by ANSYS this January. Continue reading

ANSYS Acquires Direct Modeler SpaceClaim

For all intents and purposes, direct modeler SpaceClaim is already part of ANSYS’s portfolio. The ANSYS SpaceClaim Direct Modeler is the outcome of a partnership between two companies: simulation software maker ANSYS and direct modeling software developer SpaceClaim. The corporate handshake began in 2009, when simulation software companies came to the realization that an easy CAD geometry editor was the key to broadening their outreach. (For more, read my previous post, “An Explicit-Analysis Partnership,” September 2009.) Today, the ANSYS-SpaceClaim partnership became an acquisition, also a natural outcome of the symbiotic relationship between the two.

ANSYS paid $85 million in cash to buy SpaceClaim, based in Concord, Massachusetts. Explaining the transaction, ANSYS writes, “SpaceClaim can help simplify and automate what has traditionally been a time-consuming process of preparing geometry for use in a simulation system.” Continue reading

Is Hyperloop a Hyped Dream or Practical Design? ANSYS Weighs In

If Hyperloop becomes a reality, I can go from my home office in San Francisco to Los Angeles in roughly half hour. (Lunch in Hollywood, anyone?)

The idea for a hyper-speed train (roughly 600-750 MPH) first began as a crowd-sourced project on JumpStartFund. The concept is backed by, among others, Elon Musk, CEO of TESLA Motors.

“The Hyperloop (or something similar) is, in my opinion, the right solution for the specific case of high traffic city pairs that are less than about 1500 km or 900 miles apart,” he wrote in TESLA’s blog on August 12, 2013. Continue reading

CFD for Design Engineers: Dissecting the Results

Setting up simulation jobs that accurately reproduce real-world phenomenons — how an engine heats up during operation or how fluid flows inside a catheter — takes skill and experience. So is interpreting the FEA (finite element analysis) results. The second phase is crucial in making intelligent deductions about how to improve the design.

About a month ago, with ANSYS‘ help, I put together a video covering the basic setup of a CFD job. For simplicity, ANSYS’ senior product manager Gilles Eggenspieler and I decided to focus on a very straightforward scenario: the water pressure inside a valve during close and open operations. The valve is installed at an angle, making it difficult to foresee the water’s behavior or pressure. Continue reading

ANSYS Buys Composite Analysis Software Developer EVEN

Recent mergers and acquisitions in the simulation market reveal a growing appetite for composite expertise. The explanation is simple (and it’s going to sound like a pitch from a diet program): by gobbling up composite content, you can master the art of weight loss.

In aerospace and automotive, manufacturers aggressively pursue weight reduction because lighter products provide better fuel economy. The most recent discovery is that composite materials offer a serious advantage in weight reduction. Explaining its innovative approach to aircraft design, Airbus notes, “Composite materials maximize weight reduction — as they typically are 20% lighter than aluminum –- and are known to be more reliable than other traditional metallic materials, leading to reduced aircraft maintenance costs, and a lower number of inspections during service.”

Everyone in simulation wants a piece of the composite action. This has led to Autodesk’s acquisition of Firehole Technologies, Siemens PLM Software’s acquisition of Vistagy, MSC Software’s acquisition of E-Xtream, and more. This week, ANSYS joined the gold rush by gobbling up EVEN, based in Zurich, Switzerland. Continue reading
