About the Author of the Course

Łukasz Skotny Ph.D.

I’m an FEA consultant, and academic teacher. I have been involved with FEA for more than 10 years now which included various projects in at least 20 countries on 6 continents (and a Ph.D. thesis!).

When I got hooked in FEA I realized how scarce good materials were. I have spent long nights in frustration learning everything with trial and error.

Thanks to my experience both in applied FEA and academic teaching I’m creating this course so you can avoid this frustration. FEA is a wonderful tool that can have a tremendous impact on your career – give it a try, you won’t regret it.

Throughout this course, you’ll learn everything you need to know about nonlinear analysis in FEA, which is not taught in any textbook.

Starting with the most basic concepts, neat explanations, examples, and amazing challenges you will have all the tools to spread your wings in FEA and boost your career.
Edson Zofrea Gusmões
Civil Engineer, Specialist Engineer II, Brazil

I definitely recommend Łukasz’s course. It has a lot of easy-reading content and practical examples that explain major concepts of nonlinear analysis.

This kind of plain and understandable explanation you won’t find in any scientific book. I can honestly say it helped me to develop my structural engineer career.
Jakub Drozdowski
Hull Structure Designer, NavArt, Poland

Łukasz is one of the most passionate FEA analysts and a humble person I have ever seen.

Anyone can tell his passion for nonlinear FEA through his online courses and blogs, and most importantly he is always there to clear my doubts.
Tontanga Kothilngam
WEBS SYSTEM KOREA, Republic of Korea

The definitive training course for non-linear FEA. This course comprehensively covers how to approach non-linear static analysis in an easy to understand and fun manner.

The lessons are well written and engaging and are complemented by a large number of practical example problems. Highly recommended!
Mike Beaumont
Senior Structural Engineer / Onyx Projects / Australia

A beautifully crafted experience for structural engineers who really want to understand the nonlinear effects and their interactions

If you want to be an expert in FEA Design and engineering in general, there is just no way around this course and Łukasz’s work in general.

The methods of teaching the concepts are revolutionary and deliver the knowledge in a way, that it’s just fun to learn and it really sticks.
Stefan Pumberger
Structural Engineer, Austria

This class offers clear guidelines that have made me more confident in the choices I make when using non linear stress analysis.

The combination of clear explanations and worked examples makes this course extremely valuable for practicing engineers.

I was able to use the skills learned in the course to get an experienced structural engineering position in a fascinating field.
Brian Mathews
Taylor Power Systems, United States of America

I can say without a doubt that Nonlinear FEA Masterclass is well worth the time and effort.

The way the course is structured has allowed me not only to think about (and really understand) the basics of the physical concepts that underlie this type of analysis, but also to learn the proper way to translate that knowledge into a real, reliable result from an FEA.

Each topic is very well developed, in a clear manner and with enough depth to enable students to relate these complex concepts to real life applications. You can really see the effort that has gone into making this course, which was much appreciated and helped to maintain a high level of engagement from lesson to lesson.
Sebastián Sosa

Łukasz’s approach to sharing knowledge about difficult matters proves his deep understanding of the subject.

It makes it easy to approach a non-linear FEA without worrying about overwhelming formulas and “smart” words.

There are many very well-presented examples to „learn by doing” with tricky tests, during which you can verify your own progress.
Artur Dziuda
Structural engineer, Altum, Poland

Nonlinear FEA Masterclass is an advanced course that gives you theoretical and practical knowledge to solve real complex engineering problems using numerical simulation.

The secret ingredient of the course is Łukasz, he has an amazing teaching style, he is an FEA Master, and he really makes the difference. There’s no better way to learn FEA.
Claudio Curreri
Mechanical engineer at Italgru S.r.l, Italy

Highly recommend the Breakthrough FEA Course and Nonlinear FEA Masterclass, especially to structural or mechanical engineers.

Both are extensive courses containing explanations for each of the key sections involved in FEA design with examples.

I began the breakthrough course 2 years post-graduate with minimal experience in FEA design. Following completion of the non-linear course, I felt confident enough to correctly model, interpret and validate results.
Jayden Cook
Structural Engineer at Wave International, Queensland Australia

Who is this course for?

I’ve created this course for engineers wishing to advance their FEA skillset to a completely new expert-level.

If you are looking to learn how to practically use Nonlinear FEA in structural design (and learn a LOT about proper design along the way!) while building confidence in your skills this course is for you.

This is an advanced-level course, so it would be best if you would have basic “working” knowledge of FEA before you start.

Engineering students are also welcome of course. The course teaches advanced concepts, but starts from the beginning when it comes to nonlinearities, so previous knowledge of that field is not needed, and you can start with the course with basic engineering knowledge (very basics of strength of materials etc.).
Who is this course not for?

This course teaches how to perform Nonlinear FEA analysis mostly of metal structures. I’m mentioning this, as “Nonlinear FEA” is a vast universe and modeling a “beating human heart” would be treated as “nonlinear” as well… and I can’t help you with that.

To some extent, the understanding of how nonlinear FEA works, will be useful in all possible nonlinear FEA applications, although the best benefits you will get when you wish to work with metal components/elements as this is where I have the most experience too, and naturally I’ve used such models as examples to teach various concepts.

On the same note, there is nothing about CFD here, I don’t even mention electromagnetism etc. We will focus on the structural design.
What FEA software do you use?

Most examples are made in Femap with NX Nastran, with several being done in RFEM (Dlubal). However, I strongly encourage all students to use the software they will use at work while following this course, since you want to get accustomed to software you will be working on.

So far students finished my course using Ansys, Abaqus, Staad and many other packages – examples are done in such a way, that you can easily follow them in any FEA package as long as you have very basic knowledge about it.

If you want to, you can get a 30 days trial version of Femap and simply use the same software as I do.
I’m just begining my adventure with FEA – is this course for me?

Honestly, even without previous FEA knowledge you will be able to follow the course as it teaches everything you need to know…

…however, I wouldn’t recommend that.

I feel that it’s way better to do the course when you have a solid base in FEA Fundamentals, and my Breakthrough FEA Course will serve you much better as the starting point (and you can get back to this course later with a strong foundation to build on).

Can I buy the course with instalments?

This is a terribly difficult question, and the answer is… no, you can’t.

I was thinking about it a lot! Technically “instalments” are just a loan, and I don’t want you to get in debt (at all), not to mention getting in debt to buy my course!

If you can save up some money each month (instead of paying an instalment on my course)… then please do. And when you will have all the required money, you will be able to buy the course, or do something else with them.

Loans are bad for you… don’t get them if you don’t have to!
Are there discounts for *insert whatever*

No.

There are no discounts, and the course will never be cheaper.

I know that the value of the course is much higher than the price in this edition, and I expect to increase the price in the coming editions.

The only price reduction is possible when you are buying several licenses at the same time for employees of your company – in such a case please send me an email to [email protected] to discuss details.
When there will be a new edition of this course?

Most likely around Autumn/Winter of 2026, but I don’t have very precise plans yet.

I will announce that in advance, of course.
