What Does Effective FEA Look Like in 2021?

EmailFacebookLinkedInTwitterShare

If you’ve been successfully doing FEA for years or decades, you have no doubt developed an effective process for getting the job done.  But imagine you’re a smart, new innovator just starting out today — do you think you’re going to settle on that same old process, proven as it may be?  The reality is: What once took a day now takes an hour. What once required human decision-making doesn’t anymore. What was once cost-prohibitive to use isn’t anymore. These […]

Let Design Guidance Help You: Powerful tools in xDesign on the 3DEXPERIENCE Platform to streamline your parts

EmailFacebookLinkedInTwitterShare

3D Creator is one of the roles on the 3DEXPERIENCE platform. It contains the xDesign app for 3D modeling completely in the cloud through a web browser on any device, anywhere. In this blog article I am going to introduce you to an amazing tool in xDesign, called Design Guidance. This tool will intelligently redesign/streamline your part to help you decide the best shape for it based on some simple input. It’s kind of like doing a traditional FEA / […]

SOLIDWORKS Simulation: Result Plot Tips – Part 2

EmailFacebookLinkedInTwitterShare

In a previous CATI blog accessible here, several tips were presented related to post-processing SOLIDWORKS Simulation results. It featured stress plots on mixed mesh models, showed how to present results on selected entities, and highlighted the Stress Hot Spot Diagnostics tool to locate stress singularities. Here I will mention others that I use nearly every time I conduct an analysis. Controlling plot display via the color bar The image below shows the items that are available via right mouse button […]

SOLIDWORKS Simulation: Hand Calculations

EmailFacebookLinkedInTwitterShare

Recently, I was discussing the use of hand calculations in conjunction with Finite Element Analysis (FEA) with one of our customers. His belief is that hand calculations are a waste of time, that they are never accurate enough to represent what he designs. Simply put, how can an equation referencing material properties, geometric characteristics, or section properties needed in many structural analysis calculations represent the complex designs he creates today. That is a strong and fair argument that I cannot […]

A Tropical Fish and SOLIDWORKS Simulation Meshing – What’s a fish got to do with FEA? The Bluehead Fairy Wrasse, a tropical fish native to the western Atlantic Ocean, can be found near coral reefs in schools feeding on small organisms, acting as a cleanup crew for the reef. ( ref. Bluehead Wrasse – Wikipedia). I’ve enlisted the wrasse’s help in describing the importance of good meshing practices in SOLIDWORKS Simulation. As you will see, it’s all about the details […]

Grilling with SOLIDWORKS Simulation Professional – Thermal Study

EmailFacebookLinkedInTwitterShare

We all know it’s way too cold to cook burgers on the outdoor grill this time of year. For some, the grill might even be covered in snow! With the right seasonings, however, pan fried burgers will do just fine. But although I’ve got the timing down using the grill, I’m not sure how long to cook them in a pan to get a medium rare result. SOLIDWORKS Simulation Professional thermal study can help with that. So, grab a skillet, some spices […]

Simulation Premium’s Silver Bullet

EmailFacebookLinkedInTwitterShare

Recently I was asked if SOLIDWORKS Simulation could simulate a projectile striking another object.  In this case specifically the projectile was gravel and the object was a vehicle fascia.  I had to think about this for a second.  Usually when an engineer thinks of FEA they think of a linear material, static loading cases, and small displacements.  SOLIDWORKS Simulation Premium shatters these expectations with a silver bullet by offering not only Non-Linear materials, but Transient(dynamic) Large Displacement problems.  Non-Linear Dynamic […]

Simulation Tech Tip: How to Load Results Faster and Reduce File Size for Nonlinear and Transient Studies (Results Options)

EmailFacebookLinkedInTwitterShare

Here’s a quick and simple tip for all multi step simulations , dynamic, non linear, drop  etc… You don’t have to keep ALL the data for EVERY solution step the solver takes.  The solvers will take smaller steps for convergence purposes and a solution may have hundreds of steps. For a large model this means large files and computational overhead (aka lag switching between studies. The good news is we may not need every piece of data for post processing […]

CAD Simulations: Cooking a Turkey

While I was deciding on an appropriate brine, rub and injection for this years Turkey I was curious how closely a quick and dirty simulation would come to the reality of my smoker out on the deck? So while I was waiting for the bird to thaw I started modeling one up.  Then, to calculate the fowl temperature versus time I used a 4 step process: 1. Gather Data and make Assumptions: – I’m assuming homogeneous thermal properties. – Assuming […]

SOLIDWORKS SIMULATION TECH TIP: Transferring Flow Loads to Shell Elements

EmailFacebookLinkedInTwitterShare

In SOLIDWORKS, we have the ability to take advantage of an integrated interface where we can use multiple simulation tools. If you are using Flow Simulation and Simulation (FEA), you can export Flow Simulation loads to FEA studies. In the following example, I ran flow over a truck body and exported the pressure loads to SOLIDWORKS Simulation. The goal of this particular problem is to identify the displacement of a truck cap as a function of the aerodynamic pressures. In […]
