The Coupled Eulerian-Lagrangian (CEL) technique in Abaqus is a powerful tool to analyze the interaction between structures and fluids simultaneously without the need to use different software. In this article, we will talk about the importance and applications of CEL. But first, it’s important that we get a basic understanding of the differences between Lagrangian

We all know that Abaqus is an extremely powerful FEA solver that allows us to simulate all kinds of real-world physics… but what happens when a material model or other type of physical behavior is unavailable in the tool? It might be tempting just to give up and go a different route – but not

Thermal analysis is a powerful tool in an FEA analyst’s arsenal. It is useful to analyze problems such as heating of chips in a PCB or the heating effects of a battery. There are two main types of thermal analysis – steady-state and transient. In this blog, we will discuss both of these types and

One of the biggest strengths of Abaqus is its large library of available element types, meaning that you can optimize analyses for both accuracy and efficiency. It is well known that, when we’re modeling very thin structures, such as the wall of a pressure vessel, it is beneficial to utilize shell elements rather than solids.

One of the most common questions you’ll hear asked in the FEA community is “What mesh size should I use?”, and for good reason! If your mesh is too coarse, the answers that you generate may not be as accurate as you need them to be. Conversely, if your mesh is too fine, the simulation

Mechanical engineers in their studies will learn how to do mechanical analysis on basic shapes, such as beams. However, real life parts are almost never that simple. The shapes are complex and they can be loaded or constrained in various ways. So how can we analyze these parts? The answer is through finite element analysis!

If you’ve been in the field of engineering for even a short time, you’ve undoubtedly heard the term ‘fatigue’. But have you ever thought about what it actually is, why it matters and how we can go about predicting it? If not, this post is for you! And hey, it might be a good refresher

Fidelis Industry Insights is a series of blog posts aimed at pinpointing and highlighting where Fidelis, and the industry-leading SIMULIA software we provide, can revolutionize the way our customers and partners think about engineering and business in general. In the first installment, we take a look at the Aerospace Custom Tooling industry and learn how

Plane stress and plane strain assumptions are something that we hear all the time in FEA, and in solid mechanics in general, but what actually are they? It is often assumed that everyone in the field of engineering implicitly understands what these terms mean, hence straightforward explanations can be somewhat hard to find. Here, we

Whether you’re venturing into FEA for the first time or you’re a seasoned analyst, it is important to have a good picture in your mind – and maybe even a written plan – for your model before you ever even open the pre-processing software. If you try to skip this step, you’ll likely be heading
