Free Performance Benchmark Program

Whenever I speak to our customers who want to run our software on something more powerful than their desktop computers, I hear the need for quantitative proof of HPC benchmark tests. If you have the same need, you can now get that proof, and it won’t cost you a thing.

We’ve established a Free Performance Benchmark program. Instead of demonstrating evidence of the benefits of HPC on standard benchmark models, we want to show you the time savings that HPC can make possible for your very own model. Continue reading

Improving Smoked Food with Simulation

Smoking meat (and other food) in a barbecue smoker doesn’t sound complicated, but there are more factors at work in producing delicious food than you would expect. Barbecue enthusiast Travis Jacobs, president of Jacobs Analytics, was aware that in windy conditions the air flow through the bottom inlets and the top outlet vents of a smoker can be variable, leading to internal temperature gradients and swirling air that removes smoke and makes a less savory product. He wanted to make a smoker that could smoke food to perfection in any conditions. Unlike most of us non-engineer weekend barbecuers, he turned to computational fluid dynamics (CFD) simulations to solve this problem.

The EnSight CFD Simulation Post-Processing Story: Like a Multi-Stage Rocket

EnSight, the leading post-processor for Computational Fluid Dynamics (CFD) data is now part of ANSYS. In the two decades since its launch, EnSight has taken off like a multistage rocket. Here is the story.

I grew up in that magical era when NASA used multi-stage rockets to carry Apollo astronauts to the moon and back. As a toddler I learned to count backwards from 10, 9, 8, 7, 6 … because that’s what I heard Mission Control say. I dreamt of being an astronaut, studied aerospace engineering and started my career at NASA’s Johnson Space Center in Houston, Texas. I met my lovely wife there, blocks from the NASA gates. Her parents still live next door to Buzz Aldrin’s Apollo era house. I used to store my lunch in the Mission Control fridge while working on my space shuttle aerodynamic simulations in the support room next door. So maybe it’s natural for me to think in rocket terms.

ANSYS 18.2 Enhances Simulation Speed and Accuracy

ansys 18 2We continue to expand upon our best-in-class products and platform, and deliver on the Pervasive Engineering Simulation vision, with this week’s release of ANSYS 18.2. This latest release brings increased levels of accuracy, speed and ease-of-use — spurring more engineers to use simulation across every stage of the product lifecycle to design cutting-edge products more efficiently and economically.

More companies are turning to simulation to drive increasingly rapid and innovative product development and gain deeper insight into product design.

“Our customers rely on ANSYS engineering simulation technology to cut costs, limit late-stage design changes, and tame the toughest engineering challenges. This latest release continues to build upon the industry’s most accurate simulation portfolio, offering enhanced speed and accuracy – enabling more users, no matter their level of experience, to reduce development time and increase product quality.” said Mark Hindsbo, ANSYS vice president and general manager.

Highlights of the release include: Continue reading

Structural Simulation Delivers Modular Wi-Fi Towers Quickly

Wi-Fi access today seems more like a right than a privilege. But easy access to Wi-Fi is not widespread in many countries, especially in out-of-the-way rural areas where structural design and building of Wi-Fi towers can be challenging. In the interior of Brazil, only 22 percent of the people have Wi-Fi due to the costs of installing towers and the economics of providing service to sparsely populated areas. But startup Jet Towers is trying to remedy this situation using ANSYS AIM for structural simulation to design prefabricated, modular truss towers that can be installed and running within a week of purchase, instead of the normal five weeks for custom designed Wi-Fi towers.

CFD Helps Design Marine Vessels to Withstand Extreme Waves

Most of Brazil’s offshore resources are in deep waters so Petrobras has fostered substantial expertise to develop these fields. One area of importance is the design of marine vessels to withstand the extreme waves. While the discovery of 50 billion barrels of oil in recent decades has been a boon to Brazil’s economic outlook, the location of the oil has produced challenging engineering problems. Lying hundreds of kilometers offshore under up to 3,000 meters of seawater, 2,000 meters of rock and 2,000 meters of salt, the oil reserves are some of the most difficult to access on Earth. Engineers are systematically using best design practices and computational fluid dynamics (CFD) to increase the safety of marine structures and vessels used to drill and produce oil from Santos Basin fields.

The (Technical) Kindness of ANSYS Fluent aaS, a Matlab Example

coding matlab ansys fluentMy friend, a fellow Romanian, just told me a funny story. She just relocated to the U.S. and was asking her dentist “When will I have the root channel treatment?”. The dentist kindly replied “Did you mean root canal, my dear?” 

Human kindness is a beautiful thing. As a software developer, I often wish that computer programs would be equally technically kind. Most of them are not. Many times, when a user mistypes a command, applications crash. Continue reading

ANSYS 18 Fluid Dynamics Makes CFD Simulation Practical for Every Engineer

It is hard to believe that a year has passed and it’s time to update you on what’s new for ANSYS 18 fluid dynamics. There is so much to write about and so little space in this blog!

I’m tempted to detail our breakthrough Harmonic Analysis method that produces accurate turbomachinery simulations up to 100X faster.  Or I could focus on progress with Overset Mesh that speeds and simplifies simulations with moving parts. But that is not news, that just expected.  ANSYS has been delivering new levels of accuracy and advanced modeling capabilities from the beginning. Instead, I’m going to shine the spotlight on an area you might not expect from ANSYS: Ease of use. Continue reading

Smart Home Technology and Simulation Solutions

smart home technologyThe concept of the “automated home and smart home” was first introduced over 80 years ago, and has been facing different technical limitations since then.

Recently, service providers and home appliance manufacturers have launched a new initiative to bring the concept of smart homes to reality allowing subscribers to remotely manage and monitor different home devices from anywhere via smart phones or over the web with no physical distance limitations.

Why Do Supercomputing Records Even Matter?

Some world records are the stuff of legend. The official land-speed record is 763 mph.  The tallest man living measures 251 cm. The fastest ball bowled by any bowler is 100.23 mph and the heaviest vehicle pulled over a level, 100 ft course weighs 68,090 kg.  Compared to these feats, records for supercomputing can seem a little flat. However, they are no less impressive and indeed, and stand to have a far greater impact on our day-to-day lives. Continue reading
