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.” →']);" class="more-link">Continue reading

Autodesk Simulation Nabs MVP Role At Super Bowl XLVIII

Just because the Polar Vortex has made an exit prior to this Sunday’s Super Bowl XLVIII kick off, it doesn’t mean the New Jersey Meadowlands will be free and clear of winter winds. In fact, moderately cold weather and any kind of wind gusts could have serious implications for the outcome of the game as this is a rare cold-weather, outdoor Super Bowl match up to be played at MetLife Stadium in East Rutherford, N.J.

To help football fans get a better understanding of what’s happening with the winds, FOX Sports has teamed up with Autodesk to adapt the 3D design tool maker’s new Flow Design cloud computational fluid dynamics (CFD) simulation technology to chart wind patterns and deliver insight into their impact on the big game.

Pros and Cons of Simplified Simulation: A Panel Discussion

The conversation began months ago when I posted a motion for discussion in the LinkedIn group called “New Trends in CAE Simulation.” I asked, “Do you agree or disagree? It’s dangerous to simplify FEA and make it accessible for the masses.”

There’s clearly a push among computer-aided design (CAE) software vendors to package their simulation programs for a broader audience. These programs have historically been the domain of Ph.D.-level experts. Some critics see the move to reinvent them for designers and engineers as “dumbing down” a complex process. Others believe greater accessibility to simulation through simpler interfaces would lead to better designs. →']);" class="more-link">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. →']);" class="more-link">Continue reading

DE Writer Tony Abbey, Taking Your Simulation Questions on Thursday March 7

DE‘s contributing editor Tony Abbey, a recognized finite element analysis (FEA) trainer in NAFEM‘s classrooms and online courses, is planning to field your questions in a webinar titled “FEA for Managers & Reviewers: Ask Tony” (March 7).

So I took advantage of our editorial affiliation to toss him a question that’s been on my mind: How would you distinguish the terms “simulation” and “analysis”? Are they synonymous? →']);" class="more-link">Continue reading
