About Łukasz Skotny

Łukasz Skotny is the owner of Enterfea. This company is somewhat an extension of his dreams. Dreams about better engineering worldwide, but also about self development and reaching more and more distant goals. Łukasz strongly believe that engineering is a beautiful art - he tries to deepen his knowledge to see more of that beauty, but also share this view on this blog by explaining what he finds interesting in engineering and FEA.

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 [...]

My FEA story – how learning FEA changed my life!

  However, it may sound when I started studies there was no YouTube around. In all honesty, I don't remember where people put all those sweet cat videos back then... This will be a bit personal post, but based on my story I would love to show you how learning FEA influence engineering career. What [...]

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 [...]

Verify FEA outcomes: #FEAChecklist

Finally comes the time when your analysis converges, and you have the outcomes. As great as it feels, especially if there were convergence issues, now you have to deal with results! However, this is not the end of fun! In the end, you need to see if your analysis results make any sense at all! [...]

FEA analysis won’t run? Fix it with this #FEAchecklist!

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 [...]

FEA analysis won’t run? Fix it with this #FEAchecklist!

Before you run an analysis: #FEAchecklist!

My friend and employee Asia just started a maternity leave. Since she was also responsible for training our new team member, in her "casual-self" brilliance she left her an "FEA with no stress" checklist. I've read it, and it's so awesome that I simply have to share it with you! It also gives me a [...]

Time to learn FEA

If I would have to name a number one issue people have with learning FEA, lack of time is definitely it. Being an engineer usually calls for a lot of work during a week, so every other minute is precious. But there are a lot of myths about learning, and especially learning FEA that I [...]

Fun story of the Hooke’s law

I must confess I always felt like a rebel when it comes to how I think about engineering and teaching. I'm not a complex math junky, but I don't think it stopped me to understand complex problems. If anything I believe I understand them even better... and lack of "math" simply made stuff more fun and [...]

Flow Chart: Do I need contact

Download the printer-friendly version here, and read the user guide below! We will tackle contact here. If you haven't read my posts on nonlinear supports and how to avoid contact you may find them interesting : ) This is not the first flowchart that I posted here. You can also check flow charts for nonlinear [...]

Choosing FEA software and good options you want to have in it!

A few days ago Josh sent me an email with a question about choosing FEA software. And I realized I've never actually written about it. Time to fix it I guess : ) But since I'm experimenting with videos (let me know what you think!) I've made this one about it: https://www.youtube.com/watch?v=Gq0YFTQuVL8 There are different [...]

Flow Chart: Do I need nonlinear material?

Download the printer-friendly version here, and read the user guide below! Last time I've shown you the way to answer a question: do I need nonlinear geometry? Today we will tackle nonlinear material. In the beginning, I need to confess, that I do mostly FEA about steel and other metals. This means that some nonlinear [...]

Flow Chart: Do I need nonlinear geometry?

Download the printer-friendly version here, and read the user guide below! I've already written a post on ignoring nonlinear geometry. This time I want to go way deeper into the subject. In the end, I want to create for you a simple Nonlinear Flow Chart that will help you to decide whether you need any [...]

Different types of analysis in FEA: beyond linear static!

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 [...]

Gain confidence in FEA!

Last 2 months I was really busy building the back-end of Enterfea. Finally, that is done, and now I can focus again on creating content and generally having fun! https://vimeo.com/249382190 As you may know, I'm not the biggest fan of how we teach engineering nowadays. I think that there is far too much theory in [...]

Stress singularity – an honest discussion

Arjen asked me recently about stress singularity. There are quite a few articles about this issue already (it is a common problem I think). But I want to bring something to the discussion as well : ) Stress singularity basics I'm sure you have heard about it, so I will be brief. Stress singularity is [...]
