What are the Types of Elements Used in FEA?

February 28th, 2019|

I started paying attention to meshing way too late I think. When I started my Ph.D. I literally divided elements into two categories: those that throw errors and those that don't! But even then I was lucky - I could simply check scientific papers on similar topics and use the elements that someone else used before. [...]

What’s the Difference Between FEA and CFD?

February 25th, 2019|

I got lucky (I think!). At an early point in my career, I realized I won't be able to learn everything there is to learn. Instead, I will focus on what I consider "fun" while giving myself some ease about other things. This is why there aren't any CFD articles on the blog - I simply don't [...]

Why is a Triangular Element Stiffer?

February 21st, 2019|

Somehow I never used triangular elements. Not that I knew why TRI are "bad". I think I just didn't like how they look (!). This saved me quite some trouble, proving that sometimes having luck (let's call this a gut feeling shall we?) really helps! But you don't have to rely on a gut feeling - [...]

The Difference Between Linear and Nonlinear FEA?

February 20th, 2019|

I remember my first presentation regarding my Ph.D. It was my first year on the doctoral program, and I was starting to be on a first-name basis with people that were my teachers just a semester ago. I went to the middle of the room and started talking about shell buckling... the problem was everything [...]

How Accurate is Finite Element Analysis?

February 3rd, 2019|

FEA accuracy is a topic that often provokes discussions. Without a doubt, there are FEA evangelists (I would include myself to the group!) and FEA disbelievers. So, let's take a look and wonder how accurate is Finite Element Analysis. FEA is almost like a calculator: it's as accurate as its user. But it's also quite [...]

What are Nodes and Elements in Finite Element Analysis?

January 24th, 2019|

Nodes and Elements are the very backbones of Finite Element Analysis. You will use them in every analysis you will perform in FEA, so learning about them seems like a good idea! So, what are Nodes and Elements in Finite Element Analysis? In FEA, you divide your model into small pieces. Those are called Finite Elements [...]

Choosing an FEA course

January 21st, 2019|

To be honest I avoided this topic for quite some time. Every now and then someone asks me about it, so clearly I should write a post. But the fact that I do my own online FEA course means that this may be received as an advertisement rather than advice. To "deal with it" I [...]

How to Interpret FEA Results?

January 17th, 2019|

Interpreting analysis outcomes is not simple. Even if you already have proper values from your FEA analysis, still you need to decide how to interpret FEA results. Let's take a closer look at how to approach this task! Firstly let's wonder how to interpret FEA results? In structural design, you have to perform several checks. Firstly, [...]

What Are Different Boundary Conditions In FEA?

January 14th, 2019|

It's relatively easy to perform an FEA analysis, but it's definitely difficult to run an analysis that produces reasonable outcomes. During my Ph.D. research, I've learned that boundary conditions are often the issue. Seemingly simple they can cause a lot of trouble for you - so let's wonder what are the proper boundary conditions in [...]

Math in FEA – do you really need it?

November 26th, 2018|

I never hid with my beliefs about math in FEA. But I figured I will ask around, just to make sure I'm not missing something : ) So today you get a chance to learn more about the subject! And it won't be only about my opinion on the matter but also what Tony Abbey [...]

FEA on a new level! Or how to design an engine!

October 8th, 2018|

Some time ago I realized that I've got to know some amazing people in the last 2 years of blogging. Having so many great friends feels awesome, but I figured I will push it a bit further. This is the first interview I will post here, where I will discuss FEA related stuff with a [...]

Nonlinear FEA + Snap-through with Tony Abbey

October 2nd, 2018|

This time I have something super special! We have been discussing different topics with Tony Abbey (FEtraining and Nafems) for quite some time. And now we decided to shoot a few videos about things that interest us in FEA. On today's video, we will talk about different approaches to snap-through as a difficult case of nonlinear [...]
