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.
If you’ve traveled by plane in recent years, you know the airport security drill: Put all your possessions through the X-ray detector, empty your pockets and step into one of the full-body scanners — or millimeter-wave holographic scanner, to use its official name. After you raise your hands above your head, the scanner sends out millimeter waves (mm-waves) that penetrate your clothing and bounce off your skin — or any other object you might be trying to conceal under your clothing, like a weapon of some sort. (The mm-wave radiation is 10,000 times less powerful than a single cellphone call, so you need not be concerned about any health effects.) An antenna array in the sweeping scanner device detects the reflected mm-waves and reconstructs an image of your body.
The Laboratory for Environmental Flow Modeling at the University of California, Riverside, has used ANSYS Fluent software to model a variety of environmental flows. As a third year Ph.D. candidate student in Mechanical Engineering, I recently evaluated the influence of roadside vegetation barriers on the near-road air quality using Computational Fluid Dynamics (CFD), as part of a research team that included my colleague Seyedmorteza Amini and my advisor Dr. Marko Princevac.
Exposure to traffic-related air pollution leads to public health concerns such as respiratory problems, birth and developmental defects, cardiovascular effects and cancer for people who live and work near major roadways. The near-road air quality can be improved directly by deploying vehicle emission control techniques, using alternative fuels or electric vehicles (EVs), or via passive pollutant control and roadside configuration design such as solid and vegetative barriers.

“Please fasten your seat belts, we may encounter some turbulence as we enter the clouds ahead,” the pilot announced on my flight back from a big computer conference in Denver last month. The lady sitting next to me leaned over and admitted: “I never really understand what the pilot means by that announcement.” It reminded me that you may also need some clarity about cloud computing for your ANSYS simulations.
Bumps along a cloud-computing journey can be caused by concerns about security and where the data is stored, lack of licensing options and/or end-user productivity. We have taken steps to ensure you can move in and out of the cloud smoothly, and in analogy with what I just wrote: in our case “no seat belts required.”
Nature is full of amazing materials. Wood and bone, for example, are natural composites with finely-tuned microstructures. They have optimized fiber alignment for enhanced strength. At Fortify — an additive manufacturing startup — we wondered if harnessing the power of natural composites in 3-D printing could help us to create high-performance end-use parts.
Our observations of the natural world led to the development of our fluxprint technology, which utilizes magnetic fields in a 3-D printer to align carbon fibers throughout a printed composite part. This process results in high-performance components with high-geometric complexity and incredible strength-to-weight ratios. Continue reading →
During the autumn of 1947, the sleek orange form of the Bell X-1 “Glamorous Glennis” dropped clear of its B-29 mothership and lit its four chambered XLR-11 rocket engine. The flight that followed marked a milestone in aviation history as the X-1 and pilot, Charles “Chuck” Yeager successfully completed the first controlled supersonic flight.
The lives of many pilots had been claimed during World War II by the little understood effects of compressibility on an aircraft as it approached the speed of sound and the X-1 was built for the purpose of investigating this flight regime. With only a vague idea of what to expect, the X-1 test pilots and engineers bravely pushed the speed limit leading to the momentous flight on 14th October 1947.Continue reading →

The University of Western Australia Motorsport team has competed in Formula SAE Australasia since 2001. With the help of ANSYS pervasive engineering simulation solutions, our team has won the event twice, taken the trophy for engineering design four times and collected more than 30 trophies for individual events. As of 2017, we are now partnering with Edith Cowan University Racing, another Western Australian team, in a collaboration known as Australian Formula Collective (AFC).

Today we live in a hyper-connected world, surrounded by smart products. If industry forecasts are correct, by 2020 — just 2 short years from now — there will be over 28 billion internet-connected devices. Beyond smart phones and autonomous vehicles, smart cities, smart factories, and smart homes are also quickly emerging as promising opportunities that could help improve how we live, work and play.
While these new capabilities will be a delight to us as consumers, they are a nightmare for engineers and product designers. With hundreds of sensors, microprocessors, and wired and wireless communication components, engineers face immense challenges in ensuring reliability and performance. In the complex web of electronic circuitry, something, somewhere that is left unaddressed could lead to failure. One of the big challenges confronting product designers is electromagnetic interference, or EMI.
