Customer Story: Lynx Motorsports

Lynx Motorsports is a student engineering team from University of Colorado Denver that designs and races Formula race cars as a part of Formula SAE (Society of Automotive Engineers). Each year, Lynx Motorsports designs, builds, and tests a prototype to be judged against their peers in engineering across the US. They will compete in the Formula SAE Lincoln race and design competition in Lincoln, Neb. June 20–23. We spoke to students Robert Wiley, Wesley Kaiser, and Slade Mills about their progress […]

SOLIDWORKS Simulation: Non-Linear Study of Carabiner Clip

I have always loved climbing, and at the heart of every climb is safety. The gear used should be strong enough to keep a climber safe through any sort of accident. A crucial piece of a climber’s gear is the carabiner. It is used to hook climbers to ropes, to hook ropes to an anchor, basically to hook anything to anything else. I have always been curious though, what would happen if the “gate” or the piece that closes and […]

Make Your Mark on Injection Locations in SOLIDWORKS Plastics Simulation

Over time we learn new ways to do things. For example, I recently learned SOLIDWORKS’ preferred way of creating an injection location in SOLIDWORKS Plastics Simulation. Let’s take a look at SOLIDWORKS’ preferred method to create injection locations, the benefits of split lines, and the role split lines play in the process. An injection location is where the cavity is filled from the runner system. Gates are the portion of the runner system that attaches to the injection location. Typically, […]

Automatically Find Contact Sets in SOLIDWORKS Simulation

If you are doing more with Finite Element Analysis (FEA) than just analyzing single, continuous volume parts, you need to pay attention to the contact conditions in your Finite Element Model. For SOLIDWORKS Simulation users working with assemblies, a frequent complaint I hear is how much time it can take to set up all the necessary contact conditions. For a Finite Element Model to mimic reality, proper contacts are essential. While I will not disagree that getting everything set up […]

SOLIDWOKS Simulation – Nonuniform Force and Pressure Loading

In a blog post from February, I enlisted the help of the Bluehead Fairy Wrasse to describe the importance of good meshing practices in SOLIDWORKS Simulation. Now we’ll check the integrity of her new home, a 29-gallon aquarium, using the nonuniform pressure load available in SOLIDWORKS Simulation to make sure the tank can withstand the stress of the water pressure. As you know, fluid pressure varies with depth, so using the default constant pressure would generate an unrealistic load. Figure […]

Sensors in SOLIDWORKS

I have sensed a great disturbance in my model… Star Wars jokes aside, what are sensors in SOLIDWORKS? What could they be used for? And how can they help me? We’ve written several blogs about sensors in the past. However, there haven’t been any significant changes since their initial release in 2007. Sure, there have been some enhancements like the ability to add comments to them in the feature tree, or sensing additional values like costing from 2015, but their […]

SOLIDWORKS Simulation Case Study: Stress concentrations occurring in places they shouldn’t or too high?

Finite Element Analysis (FEA) results are dependent on model, material, and boundary conditions. However, the boundary conditions have the greatest effect on the results. The boundary conditions in SOLIDWORKS Simulation must reflect the conditions in the physical experiment. A good example is the scissor lift shown below (Figure 1). As we all know, scissor lifts are designed with legs that are collapse and expand. These “legs” are pinned together. If a load is placed on the lift, then the whole structure […]

Understanding Contact Hierarchy in SOLIDWORKS Simulation

In SOLIDWORKS Simulation, contacts are crucial to the performance of assemblies. It can be said that in SOLIDWORKS Simulation there exists a rule of three. Three types of mesh, three types of global contact, three levels of contact, and so on. The purpose of this blog is to make sense of the hierarchy of contact in SOLIDWORKS Simulation. Anyone who has taken training or used SOLIDWORKS Simulation extensively knows that 3 “levels” of contact exist: Local, Component, and Global. The […]

SOLIDWORKS Simulation – Running a Static Analysis Throws an “Abnormal pretension is detected” Error

While running a static analysis in SOLIDWORKS Simulation an error window pops up that says, “Abnormal bolt pretension is detected during the modifying pretension cycle. Would you like to stop the application and check the setting?” What does this error mean and how do I fix it? There are a few reasons why this message is shown during the calculation time. At least two possible causes of this error are due to the boundary conditions that are applied. For instance: […]

Fill Your Free Surface Volume Instantly with Flow Simulation’s Initial Condition

Recently, I investigated which coil/heat source configuration would heat a hot tub the quickest. The Free Surface functionality of SOLIDWORKS Flow made this simulation possible by mimicking the water filled hot tub and the surrounding air. To find out how to heat your hot tub the fastest Click Here: Back Yard Hot Tubs and SOLIDWORKS Flow Simulation When first setting up this model I knew that the tub would need to be filled with water, and I set out doing […]
