"If you give me an internet connection and like 8 hours, i could probably solve [a differential equation]". This is so encouraging to me. I can slog through, but i have never been fast at DE. Good to hear an expert in where i want to go validating this.
I'm glad that I was able to encourage you by being honest. But this really is a truth - sure I would always prefer to "know something" rather than "not knowing it", but solving differential equations is so low on my "to learn list" that I will never get to that :) I just don't think it would add much to what I do
Thank you for the very good advices shared with the FEA community Łukasz. It will significantly help the beginners in the FEA field. Can't wait to see the next session.
Thank you Dominique! I hope to get the gear and set it up this week, so if all goes along the plan the next session should be next week :) See you around!
Hey Lukasz. The session's great. Loved it! It's been 4 years since the vid. So I wonder if any of your views have changed now? Let's say for example, if FEA is still worth it? Is mesh-less methods still nothing to fear...
Well, I don't remember what exactly I said in this video, but I don't feel much has changed for me (apart from a way nicer office I guess :P). I still strongly believe FEA is worth it (this is literally what my company does) and I'm not afraid of mesh-less methods at all in my line of work. So I guess this remains as it was :)
Hi Lukasz,Glad to find you and your lessons. thats indeed one of the best FEA Sessions.Being a Sr.Analyst who works on Passive safety systems,learnt very good info from your session.Keep up the best work.
Men, that was what I really need right now :D Thank you a lot.I 'm chemist, graduated on material engineering filed 3 years ago and i heard about FEA year ago or moreAs you said I always thought the expensive PC and software is needed to start... And I get one on student licence - great for learning. But number of properties to set just overwhelmed me. :P Now I try do develop my basic engineering knowledge as jr. Mechanical Designer, and i wish FEA as my future :)
Thank you soo much Łukasz. This is very helpful for both FEA engineering guys and all engineers. When you talk about problems with your wife because of becoming FEA Analyst, I think that someone talking about me :) I hope we can find a way for balancing work and life :)
You are very kind Telha! Indeed, what we do influences a lot of things, it's uncanny how complex life is, isn't it? Yea, I definitely hope we will find the balance, and I must say that in recent months things got better for me... so there is light at the end of the tunnel hopefully!
Hey Darrik! I'm a firm believer it is never too late to learn :) And... at 30 you have your entire career in front of you! I've started learning FEA when I was 25 I think so I wouldn't even say that you are starting "late" :) Good luck in learning! * weird... I was sure I already wrote this comment, and I can't see my previous one...
Hmmm... I've read your comment 3 times, and I'm still not 100% sure if I will agree. There is definitely something to it, I mean, it's really important to know what you are about to do, before you start doing FEA of that thing. So in this regard, an MSc in a field should be ok (but I'm not big on titles - I take the "ability to design something" over "a title" any day!). That said, starting with FEA is tricky in its own right, and initially you won't design stuff but rather learn how to do FEA, to later use it in design. Perhaps this can be learned in parallel to gaining design skills if you have a good teacher for instance. That could potentially shorten the time of learning "all of it".
@@Enterfea I came to that conclusion after watching the first 25min before you started answering to the other questions. As a BSc mecheng, I was considering to learn it from an expert. But I agree with you on the importance of exposure and certainly titles do their thing. Generalist HR always makes sure to hire someone who is overqualified rather than possibly underqualified. Also, this is a highly specialized field with quite harsh starting conditions. So apart from the expertise, one must be really lucky;)
@@emina4627 I figured that was your conclusion from the video of course - I just wondered if I agree with it :) As for "luck" this is a tricky thing. Of course, luck plays a role in life, and I can honestly say I was lucky (awesome parents, wonderful wife, healthy kids) and all that. Some of the luck also helps with business perhaps, but somehow the best engineers I know are "lucky" and others aren't. So it's not pure luck that is the factor here - skills and hard work would outweigh luck most of the time I'd wager.
Great video and your articles on FEA are super useful. I frequently check those to brush up my basics and for in-depth understandings of topics. I have one query I have learnt HyperMesh, ANSA ANSYS WorkBench & Python with 15+ industrial projects.. but due to this COVID situation unable to click opportunity related to FEA. So how's the future in freelancing of FEA?? and How can I find freelancing opportunities in FEA in this tough time.?? Thanking you in anticipation.
Hey Ashwani! Thank you for the kind words :) I'm afraid that I will disappoint you with my answer... as the summary is "I just don't know". Just after Uni I started a company, and to be honest I never "freelanced" as such. Sure, having a small 3 people team is basically an "advanced form of freelancing" in some sense, but also right now we are doing rather complex calculations, we have our Customers etc. So I cannot honestly call myself a freelancer, and as such I'm lacking in experience to give any good advice here. What I THINK should work (you know... this is internet, so while I know next to nothing, I'm willing to share this with you!)... There are a lot of fields you can apply FEA in. I guess you already are an established professional in one of them (doing all the projects you mentioned etc.). Learning something difficult folks struggle with, in that field, can give you an edge. If you are not sure what that may be, ask around... There are usually things folks "don't want to do" - for me, that was shell design (in civil engineering folks prefare to calculate "beam structures" instead of shells). Sure, it may take a LOT of time to learn all that, and become an established expert in the field, but at least it's a direction (and you grab whatever work comes your way, while you are working toward that). When you can solve something few people can, you are not a "freelancer" that does "random, low-level work" (I don't recall many folks working this way, that I know of... usually the "low-level work is done inside the companies, since it is cheaper to do it with your own people that hire freelancers in the long run... but I may be off here). When You are a specialist solving problems your Customer can't solve themselves, stuff gets easier. Of course, apart from knowing how to do stuff, there is also "convincing" your Customer that you can actually do this, and this is a completely different topic. It will be hard at the beginning. Having a decent portfolio where you showcase your relevant skills may help... as I assume you cannot count of referrals and testimonials (if you can take those as well!). Having a professional website helps too (you can do it yourself, it's not so difficult nowadays, and it costs next to nothing). The rest is just searching for companies in your industry, that may have problems with what you can solve and calling them and trying to land a meeting (I admit, that I'm lucky enough that those companies found me first somehow... and I didn't have to make those awkward calls). You may also search for companies that don't know that some problems can be solved - and show them that you actually solve that for this particular company... I know this is all rather pitifully advice, I would love to help you more, but when it comes to freelancing, I feel I'm simply not knowing enough :(
Thanks for the informative video! Can FEA simulation replace physical experiments as a method for failure analysis? The case I'm interested in is fatigue failure due to vibration. To predict fatigue failure due to vibration via experiments, one can use a machine known as a shaker. The shaker will shake a given specimen, and from the data collected, one can predict when failure may occur. Do you think FEA can give results as accurate as results from a shaker? If so, the benefit would obviously be saving money and time. Thank you so much in advance! You're super awesome for the work you do.
I personally rarely work with vibrations, but I do think that would be possible. Of course, this wouldn't be an easy task, and at the beginning, you would have to spend some time on "calibrating" your FEA models based on the previous shaker tests... but in the end, I do believe that such a thing is doable :) All the best! Ł
@@Kapilsowbi OK... I guess I should know that, but someone I haven't read about this Keyword so I didn't recognize it :) With modal analysis, I'm not sure if you will be able to predict failure. If you have an enforced vibration situation, you can, of course, aim for the modes from modal analysis to be 10-25% away from the frequency of the enforced vibrations. But this is as profound as it gets since Moal analysis is like Linear Buckling... lot's of guessing :(
Well... I have no idea. But I would say that it has more or less the same chance to replace surgeons. I completely don't worry about this. If AI will replace engineers, and doctors and... well most folks, we will live in a very different world then - I'm not overly concerned about this, but I know next to nothing about AI!

Great talk thanks alot
Thank you kindly, I'm so glad that you found it interesting!
Wonderful stream. Do you usually change those options while setting up analysis which most of begginers doesn't even consider looking at? :D
Hey! Thanks, I'm happy that you like the stream. Yea... i do change them - at least those that are my "favorites" :P

FEA does not replace the final prototype testing but it can definitely replace physical experiments
It could be possible to explain a SEMOD Analysis with example. Like how to read the modes and find the failure? We are waiting.
Hey, sadly I don't even know what SEMOD means... so I won't be able to help you here :(
