What is Meant by Degrees of Freedom in FEA?

What I really like about Finite Element Analysis (FEA) is, that it's full of small things that make you say "ah, so this is what it does!". Degrees of Freedom is just like that. It's critical to understand the very basics, but there are a few fun nuances here and there as well. Let's take [...]

Can You do Finite Element Analysis by Hand?

It's the beginning of 2009. I'm sitting in one of the lectures of my Ph.D. program. Finally, we will start to learn about Finite Element Method! My company is slowly developing, and I'm really hopeful that this will allow me to spread my wings! And then professor says: "let's start with basic matrix operations"... You [...]

What are the Types of Elements Used in FEA?

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. [...]

Why is a Triangular Element Stiffer?

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 - [...]

How Accurate is Finite Element Analysis?

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?

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 [...]
