My 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 →
In 2013, I wrote a blog showing ANSYS users how to make MATLAB apps for ANSYS Fluent. Just as a quick reminder, a friend of mine, who is also an ANSYS Fluent and Mechanical APDL user has a Windows Matlab code programming a Linux Fluent session. She had just updated her hardware. Everything is moved to Linux. She also needed to integrate a Mechanical APDL session.
She was asking me: “Why, can’t I port my MATLAB® code running on the platform of my choice and be able to also connect to Mechanical APDL?” She challenged me to to create a less than 20 lines code example. Back in 2013, my example was for ANSYS 16.0. Here is my update for ANSYS 17.0. Continue reading →
As one of today’s avionics system engineers, you have a difficult task — integrating a diverse range of functionally complex components, provided by multiple suppliers, into a system that is reliable enough to ensure consistent aircraft performance and passenger safety. You also need to understand and meet numerous regulatory operating systems and protocols, including ARINC 653, ARINC 429, CAN and ARINC 664. Continue reading →
We’ve all experienced it, especially as Halloween creeps near. The cold, inexplicable shudder you feel as you pass an old, abandoned house during a full moon. The unearthly screech of an owl or nocturnal animal that wakes you, shaking, in the middle of the night. The tingling of the hairs on the back of your neck as you pass that Jack O’Lantern that seems to be focusing its fiery stare on you for just a moment too long. Continue reading →
After completing the first circuit of the globe, this year the Automotive Simulation World Congress (ASWC) 2015 returns to Detroit. The conference is now exactly two weeks away — to be held on June 2 and 3 — and I am really excited about it. If you haven’t registered and reserved your seat, please take a moment to register. You don’t want to miss this great event. And if you don’t know what it’s all about, read on for more information. Continue reading →
In a previous blog, I shared with you my excitement about the power of the adjoint solver technology for shape optimization from ANSYS. Since then I have been working tirelessly to make this remarkable technology even more capable. CFD engineers can now understand their designs better and can perform smart shape optimization, all for larger problems with richer physics thanks to the adjoint solver technology.
My numerous interactions with people from all around the world confirmed what I knew: the adjoint solver technology is powerful and has the capability to enable a sea-change in the fluid design process. The technology is already having a positive disruptive impact on design, especially among the early adopters. Products are being improved. Established concepts about some types of fluid systems and how they function have been overturned. New manufacturing procedures are being attempted in order to produce the shapes indicated by the adjoint.
What do Tesla Motors, BMW, Honda, Toyota, Ferrari, Denso, Panasonic, SL Corporation, Cummins, Tenneco, and Honeywell, have in common? Well, not only are they leaders in the automotive renaissance, but they all delivered presentations on leading-edge simulation at the 2014 Automotive Simulation World Congress. Continue reading →
This is the third year that ANSYS hosted the Automotive Simulation World Congress (ASWC), an international conference focused on engineering simulation in the ground transportation industry. The ASWC is an annual conference that rotates between the three major regions of the world. In previous blogs, I wrote about the 2012 and 2013 ASWC’s held in Detroit and Frankfurt respectively. This year the conference was held in Tokyo on October 9 and 10. Continue reading →
We often tackle some heady topics on this blog, so I thought I’d change things up a bit by sharing a story about how physicists have helped to discover a new planet. We hear a lot about new planets being discovered, but this one is different. It has life on it. Or rather it did, before it exploded 27 years ago.
The planet is Krypton. Perhaps you’ve heard of it. It’s the birthplace of Kal-El, aka Superman.
In Action Comics 14, Superman witnesses the destruction of his homeworld.
It seems that in preparation for Action Comics 14, DC Comics asked astrophysicist Neil deGrasse Tyson if it could depict him and his Hayden Planetarium. As relayed in this interview with NPR, the physics rockstar did DC one better. He actually identified LHS 2520, a real red star about 27 light years from Earth. DeGrasse Tyson identified LHS 2520 as Rao, around which Krypton orbited before it’s untimely demise.
I haven’t read the issue yet, but apparently Superman wants to witness the explosion of his homeworld. (DeGrasse Tyson theorized that shortly after launch, Kal-El’s escape ship must have fallen into a wormhole that deposited him near Smallville, USA.)
For me, the most interesting part of the story was how these fictional characters were able to bridge the 27-light-year gap between Earth and Rao/LHS2520. Using comic book logic, Superman is able to tie together all of the telescopes on Earth to get them working in unison. Then a somber Supes can watch his planet explode. Continue reading →
Happy Friday, folks! This week, we look at innovative engineering technology that could potentially change the world as we know it — from an electronic chip that functions like a human lung to using video games instead of passwords for our data and electronics.
