3D printing solution makes it all possible – one step at a time
Imagine an automated way to feed your pets. Think of the time you’d save. Think of the hassles you’d eliminate. My kitties need to be feed twice daily, so I set out to make the process easier using both CAD and 3D printing.
For the manual method of food delivery to my cats, I have to measure out 1/3 cup of kitty kibbles with a measuring scoop and then deliver the food into each respective dish.
I have two cats, so I have to do this for each bowl, twice a day.
It would be easier just to turn a handle, and in a matter of seconds, deliver the proper amount of food to each kitty at the same time – at least, that’s what I hoped.

What is a “Vortex Across a Pressure Boundary?”
In Flow Simulation, a vortex is a region in the fluid domain which causes a swirl in a region where there is asymmetric drag in the flow field. The vortex itself is an expected phenomenon which itself is not problematic. When that vortex is allowed to generate across a theoretical boundary within a CFD analysis that can cause the results to deviate from reality in the immediate vicinity of the boundary or also cause the solver to fail to produce results at all. For that reason, it is important to note where this is happening in an analysis and take steps to avoid it.
How can this be fixed?
The vortex itself is generating because of the local solid geometry near the pressure boundary of a CFD setup. If the flow through the boundary is not symmetric, a low-pressure region can generate in front of the boundary allowing fluid to pass the wrong direction through the boundary as intended. The fix for this is to “build out” the model geometry. What does this mean? The solid model needs to have more real life geometry added to the setup so the flow field can be allowed to have the vortex and then transition into a unidirectional flow.
Solution 1: Add Geometry
An example of a vortex across a boundary would be directly from the first Flow Simulation tutorial in SOLIDWORKS.
(The tutorials can be found under ‘Help’, ‘SOLIDWORKS Simulation’, ‘Flow Simulation Online Tutorial’ once the Flow Simulation add-in is turned on). The ball valve, as it is setup in the tutorial, has two lids that are positioned closely to the ball of the valve. In situations where the ball valve is not set completely open the flow through the valve is forced to be asymmetric as it passes through the pressure outlet.
The asymmetric flow out the pressure boundary allows fluid to backflow through the theoretical pressure boundary and creates the vortex that is seen below. Read the rest of Flow Simulation – How to Handle a Vortex Across a Pressure Boundary

Human beings seem helplessly attracted to moving pictures and light, the closest example being the smartphone in your pocket. But also think about television, movie theaters, and even concert light shows — all examples of our moth-like fascination with light.
Painting with Light
“Video mapping is becoming the largest part of my business,” says Tim Burnham, president of Tempest, the world’s premier manufacturer of specialist outdoor enclosures for digital projectors and conventional and moving lighting instruments. Video mapping essentially “paints” a building with video and light, usually from multiple projectors at multiple angles.

SOLIDWORKS Electrical 2017 is here and we are super excited about some of the new features and enhancements it provides. Although SOLIDWORKS Electrical is still a relatively young product to SOLIDWORKS; it’s users have been actively putting it through its paces and making suggestions to make it even better. This year we not only see some great enhancements, we got some great new capabilities.
1. 3D Layout – Use existing assembly
You can now use an existing SOLIDWORKS Assembly to insert your electrical components to route your wires, cables, and harnesses. They have also renamed the command, it’s still under the process tab but it’s now called “SOLIDWORKS Assembly”. You can still have electrical create a new assembly or select an existing assembly from your local drive, network or Enterprise PDM.
2. Add data file shortcuts
When adding documents to your projects, such as a PDF, you can now link to the document. This is awesome because it allows you to store your reference material where you traditionally keep it instead of making copies within the project.
3. Replace attribute and renumbering documents
Both commands received huge improvements as well as new interfaces. Both make it easier to incorporate changes faster and more accurately.

Recorded Webinars – A Tool for Personal & Professional Development
It’s hard to believe 2016 has come and gone. Were you successful in completing your 2016 resolutions? I found personally, that setting obtainable goals worked best and were much more fulfilling in hindsight. Here are 3 rules I live by:
So, now that we’ve outlined how to set a resolution and stick to it, let the learning begin! Below you will find a short list of Top GoEngineer webinars of 2016.
Sit back, Grab a cup of coffee or tea, and hit play!
For this first video, you will learn about New and Enhanced Features of SOLIDWORKS 2017 according to Sean Stone, Applications Engineer. Here Sean shares some of his favorites from this years’ launch events as well as some buried in the What’s New document.
Visuals are important to the design process, stories, social media and more. They are dominating Pinterest, that’s for sure. In this webinar, you will learn tips and tricks to the Visualize Interface and ideas for new graphical content you can bring to your company.

What is a Singularity?
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.

1. Anoto’s Livescribe Smartpen, $119.99
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.
