ANSYS 19 Delivers Accurate CFD for Very Large and Very Small Details

ANSYS Fluent can simulate really big models (1)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!

Zyz Team is Simulating a Racing Sailboat with ANSYS

As an academic organization within the University of Palermo (Italy), our Zyz Sailing Team brings together students and professors with a shared passion for the design and manufacture of a racing sailboat. Our members have particular skill sets. Some are experienced with engineering design elements, such as CAD, the finite element method (FEM) and computational fluid dynamics (CFD), while others are expert craftsmen.

We began designing and building small sailing boats in 2008. Our latest challenge was the creation of Ercte, a 16-foot foiling catamaran constructed of marine plywood and carbon fiber reinforced plastic.

Fluid Dynamics are Engineer Ready in ANSYS 19.0

In early January, I spent two jam packed days in a room with over 60 of our best and brightest to exchange CFD best practices and learn what’s new for fluid dynamics in ANSYS 19.0. These are ANSYS Customer Excellence (ACE) team CFD engineers who work with you, our customers, to set up and solve the toughest simulation problems. In prior years, the presentations have focused on the latest physical models and capabilities. Certainly, those were represented. But this fluid dynamics technical meeting was predominantly about you, the engineer — discussing how to reduce risk  to provide the answers you need with the minimum investment of time and resources.

Triton UAS Team is Flying with ANSYS

Triton UAS (unmanned aerial systems) is a project team from the sunny campus of the University of California, San Diego. We are a student-run team that uses ANSYS CFD solutions to help in designing, building, testing and flying our UAV to compete each year in the Student UAS Competition hosted by the AUVSI Seafarer Chapter against teams from around the world. The goal of the competition is to promote autonomous flight. Despite the fact that the 2017 competition coincided with finals week, our team placed ninth overall out of 42 teams.

Indee Labs is Simulating Its Way to Scalable Gene-modified Cell Therapy

Gene-modified cell therapy (GMCT) represents the most effective platform for many patients with advanced disease. These therapies, however, are held back by inefficient development processes and manufacturing scales that are limited to a minute fraction of the relevant patient populations due to current gene delivery methods such as viral vectors. Simulation is helping to accelerate this development process and advance cell therapy.

Indee Labs is a Y Combinator company spun out of the Australian National Fabrication Facility. The team is developing novel gene delivery technology that uses ANSYS computational fluid dynamics solutions to gently and efficiently deliver genetic materials such as CRISPR to your immune cells. Indee Labs views gene delivery as the most problematic step in developing and manufacturing GMCTs since a global shortage in viral vectors has led Big Pharma to invest hundreds of millions of dollars into their own manufacturing facilities.

Designing A Trimaran Fast Ferry with ANSYS Fluent

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.

Do Trees Improve the Near-road Air Quality?

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.

Discovery Live Paves the Way for Rapid Simulation Results

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.

Chinook ETS Wind-Powered Car Breaks World Record with the Help of ANSYS

Chinook ETS is a team of student engineers from École de technologie supérieure in Montreal, Canada. We are trying to design and build a prototype wind-powered car with the highest possible efficiency for the Racing Aeolus event held in Den Helder, Netherlands. Our goal is not only to perform well during the race but also to develop efficient wind turbines through numeric simulations, new composites fabrication processes, advanced electronics and out-of-the-box thinking. ANSYS simulation solutions play a key role in our design efforts.chinook team with wind powered car Continue reading

How HyperXite Used ANSYS Simulation to Advance in the Hyperloop Competition

The Hyperloop from SpaceX is the future of fast, affordable and sustainable transportation.  HyperXite, our team from the University of California, Irvine, which is competing in the SpaceX Hyperloop Pod Competition, is using ANSYS Fluent and ANSYS Mechanical simulation solutions to design and build a 1:2 scale Hyperloop pod.

If successful, the pod eventually will be able to transport 840 people between Los Angeles and San Francisco at 760 mph while floating on a cushion of air. Of the 120 teams in the competition, we were the only team in the top five at SpaceX design weekend to propose air levitation as our driving force. Continue reading
