A Video On The Finite Element Method.
Ғылым және технология
The finite element method is one of the most powerful numerical methods available for solving partial differential equations; which apply over complex shapes. Very often, in engineering science, it is difficult to solve a partial differential equation, which applies over a complicated shape. The process therefore is to sub-divide the complex shape into lots of simpler shapes, on which the complex differential equation can be solved. The process then is to solve the complex differential over each simpler shape and 'join' all the simpler shapes together, ensuring compatibility and equilibrium at the inter-element boundaries. This often results in thousands of simultaneous equations, which can be solved on a digital computer. Writing of the computer program is 'relatively simple', compared with solving such a difficult mathematical problem by traditional methods. The method can be used for structural analysis, dynamics, vibrations, fluid flow, thermodynamics, acoustics, electrostatics, magnetostatics, seepage through porous media, electrical and fluid networks, electronics, etc., etc. Large commercial computer packages are available, such as PAFEC, ANSYS, NASTRAN, ABACUS, LUSAS, etc., etc; which make solution relatively simple for most problems in engineering.

I programmed my first finite element model for a 1D wave yesterday. This is amazing! One day I’d like to do numerical analysis on two generically coupled systems of Maxwells Equations (using Dynamics to predict the behavior of electric charges), which the Maxwell’s Equations cannot do on their own. My objective is to numerically demonstrate the transmission of momentum from one charge to another via their interacting fields. I have a hypothesis that if you store energy in a fuel, say, and convert this to electrical energy, you can stimulate an electrical circuit I.e. transfer momentum. So you’d conserve the momentum of the entire system, just converting it from electromagnetic to mechanical. This also means you could build a circuit that spontaneously moves without interacting with its environment.I’m not formally educated (I’m a cashier) but I am strongly motivated to learn these things over time. Again, fantastic video mate! 😊 Kind regards from Athens. Athens, Ohio that is 😂
I've never heard anything explained this beautifully. I can finally tell my family what I study! :D

This educational video of a Finite Element Analysis application by the University of Nottingham, the University of Southhamption, the Atlas Computer Lab is microfilm narration is the clear, concise description of how differential calculus, applied mathematics of Matrix Mesh equation models/solution, implemented by computer technology of large data sets, core compute power, and data visualization have come together for an effective problem definition, problem statement, problem analysis, iterative mesh equation reduction and computer graphics have help complex real world problems. Kudos to you for sharing your ANSYS know-how, experience and pedalogical/educational tools. You are sharing your wealth, quality and depth of knowledge with fellow engineers and students, who will pay it forward!
I've never been tired to watch and listen to this animated video. It has really simplified the difficulty in understanding FEM. Thank you very much.
What an amazing and beautiful video it is ! And well explained too !! Just Incredible !!!
amazing video simple lucid and interesting.
Explained such a simple and brilliant way....Well done !
What a gr8 video....I really appreciate this comprehensive explanation and the beautiful animation...Gr8 job...thanks
Explained elaborately and beautifully in brilliant way ....useful
Amazing video, I just starting to study this method to use in for my graduation assigment for my college. Thanks for sharing!
I am glad that you found my FEM video useful. I am hoping to produce some more FEM videos; but this time, on structures vibrating in water.
Excellent Video
The best explanation 👏👏 many thanks for uploading
I am currently studying FEM which is part of my MS.c courses in Nanotechnology, however it's my first time ever to know how significant FEM is, Thanks a lot for your simple elaboration.
Excellent work.thank you very much and we want more such a nice work.
This is terrific; I wish I had seen this 30 years ago. Thank you!

Best and beautiful explanation of what is meant by FEM....
This is extraordinary... Thank you
Beautifully made video. Thank you.
Thank you so much sir, This is a very good explanation from concept wise and application wise.
I love how FEM is explained in easy to understand terms, it really helped my understanding. Thank you! PS: The funky 90s graphics made me chuckle, ha.
Amazing explanation.
Nicely explained, thanks
a nice one, simply explained
Really good explanation. Thanks!
Thank you for your support.
Wow, I thought this will going to be quite disappointing, but gladly I was completely wrong! It was incredible, really well done and pretty easy to understand. Could you allow me using it as a part of an Educative Software regarding the use of FEM that I am doing for my final project of Computer Engineering? As a I am from Argentina, if you allow me its use, I am going to translate it to Spanish and make some minor changes in the sound and in the image to improve a little the final quality.
Old but gold video!!
wonderful video
A clear explanation. I understood this video about finite element method in a very simplistic manner.
thank you soo much mate. you gave much more clarity on finite element method and gave much more energy to learn about it. if there any more information please provide those links to me. i glad that i met through this video and good work.
I'm studying robot structural analysis ! and now it make sense thank you
Superb. Many thanks
Amazing video! Loving engineering and loving finite elements!

Thanks for this usefull video.
Nice explanation
Thank you very much for the upload
thanks a lot Sir , i am really happy 2 see ur site , ur a kind of inspiration 4 me...seems that ur a good human ....nice to meet u sir , please do take care of urself ...:)
Does anyone know who is the author of the harpsichord tune on the background? I heard it before and I loved it!
thanks a lot ...i am really happy that you taught FEM in such a easy way ....:) Good work guys ..all d best
Thanks sir. Really very good videos.
very good explanation
This video is so clear and amazing
I have been looking for weeks for something that explains FEM like this. Back to conditioning my solver matrices.
very good video
This is fantastic! In what year was the video made?

Wonderful, Excellent!!!Plz upload more videos like this.🙄
where can i find the papers of doing the reduction operation on large matrices from this film? i want to make some research and learn this technique
Uploaded in 2012, still indescribably helpful in 2020!!
Excellent. Now I understood Fem applications :D
Very many thanks to you all, for your support; it is much appreciated.

sirr very thankfull to u

the voice sounds like C3PO. XD
What year was this video produced?
Ninguém tem a tradução dele?
For a more extensive lecture on the Finite Element method; you can google "Carl T F Ross", & look on my website, under the link "Finite Elements & Computers".
I have made several videos on finite element methods; they can be accessed from youtube, by Googling, "youtube carltfross", and the best videos on this topic can be accessed from dailymotion, by Googling, "dailymotion carltfross31035". Many of my videos on finite elements show how to use the commercial computer package, namely ANSYS.
Hey, is Finite Element Analysis the same idea as "method"? I often see concepts with two different names, so I'm a little confused. Please clarify, thanks!

Ya they are the same.One term is used by academic people and the other by corporate people.Not sure who uses which term but they are one the same.

im an engineering student from india.. the vedio is quite awsome..but finite element analysis is lyk 'the' most confusing subject we've learned , lyk u try n try...but end up right where we started knowing nothing:(
So a very crude description would be calculus on steroids?
Now understand why I’m taking numerical methods 😂
so many indians here haha
