hey bhaijaan, PLEASE PLEASE PLEASE MAKE A VIDEO soon on the future of Finite element method/ Computer aided Engineering , is it gonna die or demand gonna decrease drastically due to Artificial intelligence, in the upcoming 5-10 years ?? Please make a detailed specific video...
Great effort Jousef. Waiting for more upcoming videos with lil more indepth topics like hourglass, shear locking instability of elements, negative volume, and common errors while running the analysis. Thanks.
Excellent, clearly explained. My goal is to apply FEM to Chemical Engineering problems, but so far I have not found a course or a book that I can understand, even when I am a PhD in simulation!. I hope with your classes I would be able to improve. Thanks very much
Thanks Giner my friend! As for courses I’m working on general ones in the beginning and go also for things such as OpenFOAM or SimScale. Make sure to follow me on my socials. My learning Academy will go live in a few days :)
Really good introduction to FEA for someone who already has some background about it. I hope you will get into mathematics with this same ease. Wishing you all the best for all upcoming videos.
@@JousefM I was talking about FEA mathematics. Well good that you are thinking of Linear Algebra as well. Also you mentioned Gilbert Strang, so till now his videos are the best place for me for Linear Algebra.
We need a bit of Linear Algebra but FEM maths will follow I know what you mean, like weak form etc. - Gilbert is the best, will be very Hard to beat the quality!
Absolutely fantastic video joseph. I always want to know some historical background so that I can appreciate that subject more. Thank you so much for arranging all of the data so neatly in one video. Please don't delete this video ever.
I searched alot about finite element on you tube , this only provides me required information.If possible please upload some more about finite element analysis.Thank you
Your way of teaching is really great. Can you please provide some example using calculations of actual function like e.g: f(x, t) = x^t etc. or a simple differential equation like a wave motion. And for next lesson if you can extend it to a 3D lattice approximation that would be awesome.
Video was very helpful in understanding the basic working of FEM as a newbie to FEM .I appreciate your efforts in making this video and I expect more videos in this FEM series

Hey Arman! Actually my viewers decide that. If you follow me on my socials, you might have seen that I am currently working on a small Cousera "Guided Project" which I will release soon, that will be FEA for absolute beginners. In the upcoming guided projects, I will include some of the topics listed at the end of the video. If you want to stay up-to-date with my progress there, either follow me on Instagram and/or Twitter :)
Thanks for this excellent video. In your example of a 1-d axially loaded bar, I expect what ultimately you want to find is the displacements {u}, right? In on your equation [K]{u}={F}, you know [K] but you don't know {F}, and you're trying to find {u}, so don't you have too many unknowns? If possible I'd like a simple example where you get numeric answers, not just a relationship between {u} and {F}. If I know F4, can I write F2 and F3 in terms of F4, something like F3=-F4 and F2=-F3? Then I know all the Fs, and I can solve for {u}. Is that how you could use this equation?
Very nice video and good explanation. I could not find your next video about other topics such as singularity,Linear and Non-linear?, Would you be able to send a link here?
These were all suggestions from my side but I will definitely will work on them soon :) I am planning to release a course on FEM soon so stay tuned for that as well :)
In planning! Currently working on more Coursera courses and my own ones, but I have already my video production list for FEA ready. What would you be personally interested in?
@@JousefM Im currently studying mechanical engineering and would like to obtain a more fundemental understanding of FEM. But also get familiair with ots limitations.
Good point Seif! u = displacement L = Length of the beam epsilon = strain For more details, have a look at this page: www.engineeringarchives.com/les_mom_truestresstruestrainengstressengstrain.html#:~:text=Engineering%20strain%20is%20the%20amount,length%20as%20given%20by%20Eq4.
Loved the video Jousef. Clearly explained. What is the model of the skull you showed in the video - the one with a circle in the middle of the forehead?
Plenty in the pipeline - as I am currently finishing up my first coursera course I’m a bit behind for videos. What would you personally like to see? :)
Are you a beginner? The upcoming videos from me will definitely help you out, I planned a course for the future with applications as well as programming exercises which does not exist in that sense so far. Let me know what you think!
@@JousefM thank you for a quick reply. Actually I am working in preprocessing stage as meshing, connection and assembly of full vehicle for crash domain for 2 years. I wanted to know if any specific MS program is there.
@@realisticmonk804 For crash simulatin in general I would recommend LS-Dyna, they are quite famous in that field and companies like Porsche use their software to simulate crash tests.
@@realisticmonk804 Thanks for being such an active subscriber :) I already uploaded another one about 2nd order differential equation and how to solve it in MATLAB. By the way, I have started a poll which you can find on my channel in the "Community" tab. Feel free to vote what you want to see next! :)
Nice topic Tarang! I think that this here is a good start: ethz.ch/content/dam/ethz/special-interest/baug/ibk/structural-mechanics-dam/education/femII/presentation_09_thermomechanics_v2.pdf - I can see if I find some good books that I could recommend.
Thanks Jousef... Its so nice of to reply this soon... I will definitely look to this presentation... And also eagerly waiting for your next videos so as to revise my FEM...
Did you cover the other topics mentioned at end of the video. I cannot find more videos related to FEA. I would be interested in some of the topics, hourglass, shearlocking, manage projects etc.
I think i need simple examples that we can solve by hand to really understand this (for a simple grid). Is that even possible for very simple systems. Maybe solving at least for one timestep?
@@JousefM Thanks for the reply! Well, i was talking about CFD mainly. I don't understand yet how i would solve some form of the navier stokes equation to go from some initial condition to the condition after one timestep (in a small 2D grid).
Ah got you! Thought because you were commenting on the FEM video you also were referring to it :) But definitely possible to do that. The easiest and most intuitive way would probably to explain this with Finite-Differences
Moin, Jousef, also habe ich mich schon bei Cousera an Ihre Projekt teilgenommen, aber welche Kontaktmedien ist besser, wenn ich Frage zu dem detalisierte Dinge des Projekts Ihnen stellen könnte? Also Hilfe brauche. Danke schön! :)
Moin und danke :) Am Besten über Instagram oder Twitter. Versuche dann so schnell wie möglich zu antworten! :) 🐦 Twitter: @jousefm2 // twitter.com/Jousefm2 📸 IG: instagram.com/jousefmrd/
@@JousefM Mach dir kein Stress, hat nichts mit Deutsch Akzent zu tun ;) Ich hab selber Maschinenbau in Deutschland studiert...Deine Erklärungen hören sich bekannt an :)
Hello Mr. Jousef. I'm taking the coursera course that you made about FEA, and in the tuto, you clicked a switch that activated 2nd order meshing. I can't find that option though. Maybe there was a simscale update and they removed that. What do I do instead to get second order meshing?
@@JousefM I haven´t found any article in the documentation about it. Recently, I clicked the event log of what you labeled Mesh Linear and it indicated it was 2nd order. So now I will need to set a first order mesh, but I don´t know how, since the order is automatic.
Hi, thank you for your video. I am a newbie in CAE and I want to learn more about FEM/CFD. So, can you recommend for me some courses teaching FEM/CFD basics? Thank you so much.
Sure thing mate! :) Thanks for watching. I can recommend my small Coursera courses for hands-on projects: www.coursera.org/instructor/jousefmrd - these do not go into much theoretical details. I can recommend the courses from Lukasz Skotny or Dominique Madier, experts in their field and very good teachers! I am working on a CAE Masterclass as well as separate CFD & FEM courses here: academy.jousefmurad.com/ - sign up for the course newsletter, no spam :)
That’s the only FEM video I have so far. More to come soon 🙂 I’m finishing up coursera courses at the moment on using SimScale for FEA and CFD. Stay tuned mate!
You could use as many nodes as you want. The more nodes you use, the better the accuracy but you need more time to compute the solution. If you use less, you have a less accurate solution but you're faster. For showing how the FEM system works a low number of nodes make sense then you can actually see how easily the matrices can be assembled (assembling process := putting the individual systems together).
@@abrorabyyu6221 Coursera mini course (called "Guided Project" for absolute beginners) is in production, hopefully finished soon :) Stay tuned. Make sure to follow me on Twitter & Instagram where I keep my followers posted about latest updates, course creations etc.
Approximation method to solve partial differential equations - imagine you do a crash test, way too inefficient to do hundreds of crash tests and there is simply no analytical solution for a deformation of a crash per se. Radical but very easy to understand example :)

@@JousefM please make it soon brother... I know you're busy in podcasts, but please make a room for this topic soon in your list of podcasts/videos ....maybe arrange a podcast including all these questions with Mr. Lukasz Skotny
