A singularity is a function’s divergence into infinity. Simulation occasionally produces stress (or heat flux) singularities.
How do they occur? Mathematically, the solver uses matrices to represent the elastic field (displacements of the elements). When a highly localized load is applied, the gradients of the displacement vectors begin to diverge, causing the roots of the matrices to go to infinity. For a simplified explanation, see the stress equation below. Stress goes to infinity due to force applied in a very small area.
Where do Singularities occur?
Singularities are usually seen at points, edges, or reentrant corners. Reentrant corners are interior corners, with angles pointing into the part. The high stress concentrations are usually seen near 90 degree corners, but can potentially occur for any angle less than 180 degrees.
Why don’t they occur in real life?
Think of the common case of singularities created on interior corners. In software, that corner is perfectly sharp. In real life, there will always be a slight bend. Also, the part may deform slightly, or “slip”, and allow the faces of the corner to slide against each other. The slight bend and additional friction allow for a converging stress.
“Adjust your legend’s color settings to grey out above the material’s yield point. This prevents singularities from overshadowing other important stress results!” – Joe Engineer, Know It All, GoEngineer
I write lists. On paper. With a pen. Writing helps me remember, while typing with my thumbs on an itty bitty screen does not. Then I struggle to coexist between a paper and paperless world. But Livescribe solves that. It’s a Smartpen that houses an infrared camera, ARM processor, Bluetooth Smart chipset, flash memory and lithium ion battery all work together to bring your notes to life on your tablet or smartphone. Android and iOS friendly.
Let’s talk about your SOLIDWORKS network license and debunk those myths with facts. Which one of these 5 are you guilty of believing?
You accidentally received extra licenses (yassss!).
Not true. Only once in 5 years have I seen SOLIDWORKS write an incorrect license file. The way licenses are listed in the SNL can be misleading. Suppose you have a network license containing 1 Professional License and 1 Standard license. The SNL will show 1 Professional License and 2 Standard Licenses. Why? Because when you are pulling a Professional license, the license manager is releasing a Standard license and the Professional ADD-INS. So really the license manager listing should read “Professional ADDINS”, rather than “Professional”. You cannot pull a Professional or Premium license without pulling a Standard license.
You don’t have the ability to use SOLIDWORKS on your home computer.
For me, riding my motorcycle is having the freedom of the open road and traveling with the wind in my hair! Sounds great, right? Well, after any extended period of riding in the weather elements; physical and mental fatigue takes over, leaving the operation of a motorcycle quite dangerous.
On my quest to create comfort and extend my riding to a long haul, I decided to improve the stock windshield (or windscreen) of my KTM SM-T. This is where aftermarket parts, SOLIDWORKS and 3D printing technology takes over.
Motorcycle Windscreen: Stock vs Touring
Take a look at the stock windscreen below. It looks ergonomically ‘sporty’ but doesn’t provide much protection from the weather elements.
In comparison, you will see a touring windscreen below. This version is significantly taller but still does not provide the necessary protection from the weather elements.

Injection-molded plastic part design is a job thet tends to fall into your lap. You have zero qualifications, and yet, you are supposed to do it perfectly while blindfolded. It’s difficult to lunge forward with confidence when you are building on a poor foundation.
The result is that you proceed with the project with a “learn-as-you-go” approach. Even so, there’s still opportunity to avoid common mistakes, make smart decisions, and release a smart, young, well-prepared injection-molded part into the universe, ready to make a big impact and change the world.
Ever wonder why rubber weights are used in Olympic weightlifting, but iron plates in most gyms?
We did. So, we looked into it.
The World’s greatest athletes demonstrate what it means to push the boundaries of human potential at each Olympic Games. In Olympic weightlifting, for example, new records are being set every year. Much is said about the athletes and how they challenge their limits to achieve new heights, but what about the equipment?
Has it always been the same?
What kind of stress occurs when the bar is dropped?
How could pushing the boundaries of design enable athletes to achieve more?
At GoEngineer, these are the kinds of questions that keep us up at night.
Here’s what we found; changing the material of the weights, changed the sport of weightlifting.
Weightlifting has been an Olympic event since the very first Olympics in Athens in 1896. Back then, the bar and the plates were made out of iron. The rules required athletes to gently return the weights to the ground. This obviously wasn’t possible when an athlete was going for a max effort lift, and would miss.
Your marriage to SOLIDWORKS is on a good steady road and then, all of a sudden, either (1) the boss asks you to get SOLIDWORKS CSWP certified or (2) you decide on your own to get certified. Not all certifications are planned or intentional, but if you find that an exam is on the horizon, you can still take steps to prepare for a healthy full-term certification.
SOLIDWORKS Exams are completely paperless, timed exams. The CSWP exam is broken out into 3 consecutive segments “trimesters”, totaling 3 hrs and 30 minutes of active labor. Answers are usually not multiple choice. Testers submit answers by manually entering a value: the volume, weight, or center of mass of your SOLIDWORKS model. If you’re really good at cheating on tests, you won’t fare well on this exam. Be aware that you are going to have to give birth to your very own SOLIDWORKS creation starting with not so much as a zygote.
Question 1 starts with something along the lines of “Make this.”
Seems reasonable…until Question 2 slams you with something along the lines of “Change what you just did into this whole other animal.” [insert expletives and panic here]
Just remember that getting a Certification is a beautiful, magical thing. It’s just as much about the journey as it is the end result.
Over the last few years, GoEngineer hosted a series of technical events in late spring. During these events, we showcased how our technology platforms work together to produce efficient workflows. Last year’s event was a little different. We packed 12 topics into 6 timeslots for a full day of learning. With over 2100 attendees during the last few events, we want thank you, our client partners, for this huge success!
Shape Your World Is On Its Way!
We are back at it this year with an exciting new project and schedule of topics. Shape Your World is the place where you can explore technology and learn processes from our experts. This is the perfect opportunity to catch-up and collaborate with old friends. You might even find a new one! With 7 time slots available starting at 9AM each day, we allow you to customize your agenda while attending several sessions that best fit your needs.
Batman v Superman – Who will win the battle of the ages?
Batman v Superman: Dawn of Justice hit theatres worldwide. Previews clearly show Batman holding his own against Superman. As an engineer, I’m a Batman fan at heart. I want to believe that the Caped Crusader will ultimately defeat that Kryptonian. So, let’s take a look at this matchup and use engineering technology, all available to Wayne Enterprises, to devise a plan of attack.
