Engineering problems can be quite straight forward when confined to a single size scale. For example, designing an elephant-proof fence is simply an exercise welding together enough big steel bars. But what if it also has to confine mice? By mixing the very large and very small size scales, the mouse introduces a whole new set of problems that will greatly complicate the design and construction of the fence. Tiny gaps irrelevant to the elephant can be escape ways for the mouse!
Multihull ships create engineering challenges that are “out of range” of conventional ship design techniques. They require complex, CFD analysis to optimize multiple performance variables like resistance, endurance, stability, seakeeping, etc. In this article, we take you behind the scenes at KUASAR MARIN Engineering Inc., where we leveraged ANSYS Fluent to explore design iterations for a three-hulled, high-speed passenger ferry that could compete with existing two-hull catamarans.

I was recently presented with a unique opportunity to compare the results of full ANSYS CFD simulations with the results obtained using the new ANSYS Discovery Live product, which provides results instantly upon changing the geometry without interrupting a run. I was very pleased and surprised by the speed and accuracy of Discovery Live in this comparison test.
I work for Astec, Inc., the subsidiary of Astec Industries that builds asphalt plants. Roadtec Inc., another Astec Industries company, builds asphalt pavers, reclaimers and material transfer vehicles (MTVs). An MTV helps to accomplish non-stop, non-contact paving by offering a continuous supply of Hot Mix to the paver. By separating dump trucks from the paver this way, contractors are able to make a smoother finished road.
In the world of stock-car racing, finding even the smallest competitive advantage is the difference between winning and losing.
That’s why at Richard Childress Racing, we design and build our race cars end-to-end. We engineer and machine our own chassis and suspension components, we design and fabricate our own bodies, and we test and build our own engines. Everything is built from the ground up at RCR.
Another release of ANSYS fluid dynamics products, another round of great new capabilities. While some may say that a picture is worth a thousand words, I invite you to view the video below for more than 16,000 words on 16 Cool New Features of ANSYS Fluid Dynamics 16.0. And they are all winners — so this is not a ranking, just a list! Continue reading
