## The Difference Between Linear and Nonlinear FEA?

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?

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 [...]

## Choosing an FEA course

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?

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?

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?

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!

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

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 [...]

## Design rules vs Physics

This came out in one of the discussions in FEA guild, and I figured I will expand on this idea. This will also be useful for me later (and if I convince you, it may be useful for you as well). Instead of having this discussion with every Customer, I can simply direct them here [...]

## Blas Molero on Enterfea HERTZ Contact in FEMAP: CGAP elements

Hey people! I continue the trend of inviting some of the FEA-finest to write on the blog! This week none other than Blas Molero Hidalgo joined us with his awesome work! If you use Femap and you ever searched for an answer in google you know who Blas is. He has this superpower I don't [...]

## FEA Design Tips #003

It's high time to make another one of those : ) I recently got caught up with some urgent designs, and those required revisiting some stuff I did several years ago... but I think I will feature this in future advice! Let's go with the tips! Pssst - there is also a video with those [...]

## Great FEA report for the win!

I've recently posted a tip about writing good FEA report... and I must admit that what followed surprised me! This is the most discussed topic to date. Naturally, I figured I will expand some of my ideas into a longer post. Let's give it a try : ) FEA report: business or tech? I strongly [...]

## Angus Ramsay on Enterfea: Large Thermal Strains in FEA

Ok, I'll admit it - I'm excited to host a post by one and only Angus Ramsay! Before we get to the post, let me just say that I actually have a chance to work with Angus on a book for Nafems (about FEA of course). So hopefully, you will see us (along with Nick [...]

## FEA Design Tips #002

Wow... it's the next week already O.o This means that it's another roundup post! I will always be a week behind on what we talk about in the Facebook group (even more reason to join it!). This is on purpose - I simply want to get all the insight and those awesome discussions that happen! This [...]

## Nonlinear geometry benchmark

During last week I've posted a tip in the FEA Guild about using Benchmarks. Some great pointers were in the comments, but one got my attention the most: While there is no chance that I will build such database myself, I'm pretty sure we have a chance of making one together! I will try to [...]

## FEA Design Tips #001

Hey People! I've recently started posting FEA Design Insights on my LinkedIn profile as well as in the Facebook group (where some awesome discussions happen). I figured I will make a roundup with the best (and most interesting) tips here... just so they will be there where you need them! Let's start with a roundup [...]

## How to Learn Finite Element Analysis?

I well remember when I started learning FEA. It was the beginning of my Ph.D. and no one told me that shell stability is highly nonlinear and that FEA will be difficult to do. I just assumed I was too stupid to understand this, and I was regularly hitting a wall with my head. Now, [...]

## Plasticity, isotropic/kinematic hardening… and Boris!

Hey you all! This is something special - first time on my blog I have a post done by someone else! Do you recall that Boris Jakimov made it to the hall of fame in the snap-through challenge? We talked a bit afterwards, and this is the result! I won't edit Boris work*... but I will [...]

## How to approach a snap-through problem

Today's post is a video : ) In it, I will discuss various approaches to snap through problems with nonlinear FEA analysis. Understanding this was a stepping stone in my career. I really hope it will be just as useful for you! https://www.youtube.com/watch?v=GA9MyT7ax_k Takeaway: Let's sum up what I talked about: What is steering? When you [...]
