We regularly need to model contact between parts within FEA models. After all, not many of our simulations will include only one component, and as we begin to increase the complexity of our jobs, we tend to prefer contact over traditional ties and glue. On occasion, it is simply not possible to obtain static equilibrium
An interview with Robert Hurlston Remain curious and keep learning; develop your professional network both inside and outside your company; be known as a helper; become the best communicator you can. Today, I had the pleasure of interviewing Mark Bohm for the latest in our series of interviews titled ‘Excerpts with the Experts’, in which
An interview with Robert Hurlston There is a lot of knowledge and different concepts to be learned in the field of simulation. Each of them must be taken one by one and experienced in order to understand all the details and to be able to apply them properly in our simulations. Becoming a simulation engineer
When running a finite element analysis, one of the first decisions we must make is whether we think it should be considered a static or dynamic problem. But what exactly constitutes a static and a dynamic problem? And which analysis type is most suitable for each? In this post, we aim to break down these
Many of us are familiar with the terms first- and second-order as it relates to finite elements, but that doesn’t necessarily mean we all know how and when to use them. Today, we will be discussing a few key points regarding element order and making a case for why it matters to us as CAE
FEA models come in all shapes and sizes. While sometimes we’re trying to find the stresses in a stiff, steel structure, others we might be looking at the behavior of a thin membrane or the buckling of a slender column. You may have heard the term ‘nonlinear geometry’ before, but perhaps are not really sure
As we have discussed in some of our previous blogs about Element Selection in Abaqus, choosing the appropriate finite element type is critical for obtaining accurate and reliable predictions. However, with the vast array of available element formulations in Abaqus, this can sometimes be challenging, particularly for new users of the software. Because many novice
Have you ever performed an analysis on a seemingly robust structure only to discover stresses that exceed the allowable limit by orders of magnitude? As experienced analysts, this is likely a problem you rarely encounter; however, when first delving into CAE, many engineers run into confusion when interchanging between unit systems. So, why does this
Fidelis is thrilled to announce that James VanWagnen has joined the team in the role of Project Engineer. James is no stranger to Fidelis, having worked closely with the team during his time at American Axle Manufacturing. His passion for problem solving and strong mechanical background make him the perfect addition to our growing organization.
When performing Finite Element Analysis (FEA), there are many factors that can influence the accuracy of the simulation, the most critical of which may include mesh size and element quality. Mesh size, as you might guess, refers to the geometric dimensions of the element: length, width, and height. Element quality, though, is a bit more
