It's time for the second part of the #FEAchecklist! Last time we were checking stuff before starting an analysis. Now, let's wonder what to check if you see analysis errors when your analysis fails to run. I can honestly say I'm kind of an expert here... I'm pretty certain I've made most of the possible [...]

https://youtu.be/inVGiGzmii0 As promised in the video, you can get my free FEA essentials course. and free nonlinear FEA introductory course! Different types of analysis in FEA (text) Just so you know: this will take around 15 min to read. As I wrote recently this year I want to help you gain confidence in the FEA [...]

Do you need to know math behind FEA?

By |November 30th, 2017|• Linear Analysis, FEA: Basics, • Nonlinear Analysis, FEA: Intermediate, FEA Topics:, Art of Engineering|

Recently I asked a lot of my subscribers what they think is the most difficult thing in FEA. While "interpreting results" or "too much theory in materials" appeared quite often, I also got several answers like: My biggest obstacle is actually understanding the mathematical concept behind it. Although I am really interested in the application [...]

FEA results verification with hand calculations: stability

By |October 19th, 2017|FEA: Basics, FEA: Intermediate, • Post Processing, FEA Topics:|

Last time I described 5 steps to FEA results verification. Among those steps were FEA results verification with hand calculations. I figured it makes sense to expand on this idea. Especially since Luke asked me about something on this topic via email. Luke asks: How is the eigenvalue calculated, can this be done longhand? Can [...]

Changing active forces for enforced deformations and vice versa

By |May 23rd, 2017|FEA: Basics, FEA: Intermediate, • Boundary Conditions, FEA Topics:|

I have seen many mistakes where people wrongly changed enforced deformations with active forces. In some cases, this is a simple task, which gives beginners the feeling that they can always do it easily. This, in turn, leads to various mistakes in analysis. I think it is worth discussing this, to point out common mistakes [...]

Finite Element Analysis workflow

When I first started working with Finite Element Analysis (FEA) I had a huge problem in understanding what to do. I had a basic engineering knowledge but I simply did not understand what was the order of the steps. Suddenly the software had many "modules" and each was screaming at me that some data is [...]
