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
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

The Fidelis Fun Features series is aimed at taking a lighthearted approach to learning some of the more advanced features of ABAQUS in a fun and
Have you ever found yourself wondering which Abaqus element formulation is most suitable for your analysis? With the vast options provided within Abaqus Standard and Abaqus Explicit, novice and experienced users alike often find themselves asking this very question, and for good reason: selecting the appropriate element type with respect to your simulation objectives is
When we run a structural Abaqus model, it might be fine to assume linear-elastic material behavior. This means that all of the deformation caused by loading is fully recoverable and no permanent damage or ‘set’ is incurred by the material. This is the case only when the analysis does not generate stresses exceeding the material
As CAE analysts, one of the most challenging aspects of our job is balancing the tradeoff between simulation accuracy and solver efficiency. What good is a simulation model that runs in five minutes but doesn’t mimic the real-world physics? Conversely, how valuable is a well-correlated methodology that takes weeks or months to solve? Although both
We hear it all the time, and most FEA codes spit it out as if it’s the holy grail of field outputs – but what actually is von Mises stress? Hopefully this post will help you understand that a little bit better, and to realize how constitutive FEA material models are taking some liberties with
