What a video, sir. Thanks a ton for going thru the smaller details and explaining what is a node and what is its role. This video is indeed a FEA of the topic.
Thank you very much for sharing your knowledge. Good, simple and direct. I just would like to make a note: At 6:57 you say that we invert the K matrix but that is not necessary and often better to avoid. Although I understand the educational intention in the simplicity of the statement I would like to clarify that for medium to large systems of equations (millions) it is NOT advice to explicitly invert the matrix but use a linear system solver instead. Reasons (maybe a bit advance for newcomers): Normally, the matrix K is very sparse (contains mostly zeros) and, because we don't want to store all that useless zeros in memory, we only keep track of the non-zero values. In the moment we make an inverse, we do not (necessarily) get a sparse matrix back and that means that the required memory is exponentially more. In addition, matrix inversion requires more operations and will introduce more numerical errors than direct solvers, like Gaussian Elimination. Again, thank you for contribute in the spreading of this amazing technology!!!
A nice clarification. You are absolutely right, I use the expression 'invert the matrix' purely to indicate what one might do by hand. When I discuss this in class, I usually point out that there are more efficient methods, though the end result is the same.
Good one. In fact, this video is the best of the bunch I binge-watched last week. Will recommend this to my students (TU Delft IDE, MSc level) as additional content for my keynote lecture on "Funny Elephant Analyses". Thanks!
Professor Ken Ludema (said in a summer tribology course) said it was Finite Elephant Analysis because modeling even simple system grew to the size of an elephant rapidly and eating a elephant one bite at a time is possible - but has diminishing returns.Excellent presentation! Thank you!
Thanks for sharing such an informative video! I am wondering if you tell us which book to read for beginners in FEA. I am materials science and engineer students and interested in heat transfer and fluid flow analysis during sintering parts in powder metallurgy. Thanks.
Hello. Is there a book you'd recommend to read about this topic? My bachelor's paper next year will possibly partly be about FEA, so I am slowly starting to gather knowledge from a few different sources. Thanks!
Finite elephant analysis.
Haha
Oh, you can read and hear! Congratulations!
@@aerodynamico6427 Yes, a new skill.
You beat me to it.
Lolalalol
As a former lecturer, I must say you are awesome.

one of the best FEA lectures i have seen

This is a very good video as someone who has spent a long time on it without actually knowing what was going on you have made it perfectly clear.
Thank you.
WOOW! Such a refreshing vibe in this lecture! Got to know the overview so well.

Concise and clear. Much appreciated!
Glad it was helpful!
I had to pick one FEA playlist to watch. I chose the one with funny elephant

I like that explanation! Thanks for sharing.
explanation well done. you deserve more subscribers.
Very well done!
Thanks. Very well explained.
Man, you're brilliant ! Thank u !
Thank you!
very very good...
please upload video about result colors.. how to read and understand final result colors after analysis.
well explained!!!!!!!
Thank you!
You're so good in teaching man, it would be great if you can release the slides for us study from

There are certainly a lot of great beginner textbooks out there. I use Logan's book because I think it has particularly clear explanations.
thank much, that's refreshing
nice to learn
Thank you
Thanks man 👍
i guess u should first mesh the model and then apply loads and boundary condition. I am not sure about ur steps. I might be wrong.

Thanks for these videos, plan to watch them all! (I'm a mechanical engineering student.) But, who are you and do you have other channels?
Thanks, I'm glad they are helpful. I teach ME at Cal Poly SLO. This is my only channel.
@@schusterengineering thank you sir,
could you teach the coding aspects of FEA, as well, Thanks a lot..
Love from India.
I don't understand the definition of degree of freedom. Can I please break it down?
Thanks
nice video
Thank you.
Sir kindly tells about the software of fem
What was that noise at 4:53? It took me off guard
👍
I have doubts regarding FEA
I GOT IT IS GOOD
Sir, which book are you referring to?
Hello my dear Dr.
Can you kindly provide me with your materials pdf of Finite element Course, please 🙏🙏🙏?
Go Mustangs!
Where is part 2?
Here's the full course playlist: th-cam.com/play/PLBwQ5Llf4Q_Vj8xKcxsbzIfdqrtzcHLbe.html
4:53 - you still use ICQ ?????? 🤣😂🤣😂
I thought my skype was starting up at 4:53
Seriously, that frightened me a little.
accident
Poor teaching
Cryptic, no worked examples
Basic materials
Slow without any focus
