I think there are very people few who can convey thier message so cleanly. You are one of them I would say. Thanks for the video. It would be nice of you if you make further videos on related to 2d problems.
This is incredibly useful, keep doing this great videos. You should consider doing this series of deriving the stiffness and mass matrices, applying the theory to FEM and coding it; also for plates. It would be extremely useful. (btw, subscribed :P)
Just a small improvement: when removing the fixed degrees of freedom, we should do `for dof in reversed(sorted(restrained_dofs))` in order to make sure we delete the right dofs when we have several restrained dofs. Keep up the great work!
Excellent walk through, really helped with numpy and the basics of engineering style FE. Would the code for a 2D problem concerning fundamental frequencies of a plane, say, look more or less the same?
Give it a try in a Edx Python for Scientific Research, it will give u a good basis on the scientific libraries. For the FEA programming, try the MATLAB for FEA, I pretend to 'translate' it to Python, but it will take a while, but almost all the MATLAB's functions can be emulated in some way in Numpy. See ya.
We can calculate the maximum possible error without actually knowing the measurement. If I have a stopwatch that measures times within 0.1s, then I know my accuracy is within 0.1s - even without having measured the duration of an event. Also, I would then know that it was impossible to get accuracies of 0.01s with this stopwatch - regardless of what I was measuring.
@@Freeball99 thank you so much. It makes more sense now. I passed FEM and it was so theoretical that I didn’t get the deep understanding of it! which textbooks would you recommend?

I definitely agree. Applying FEM for plates would be extremely helpful.
Well and beautifully done Andrew .... Keep the excellent work going on ....!!

Yes, that's good advice in general. I didn't want to get into that for such a simple problem.
Very Nice, Now I'll start to program a code FEM on Python. I'm a matlab user.
Wow the best channel I ever have seen, Subscribed right now
Need more videos on FEM!!!!
That was clean! Many thanks indeed!
great job man!
Nice Stuff. Keep up the good work...
Thank you for your helpful video

Hi!thank you for the video .I am trying to code finite element with a thermal problem on python .Would you like to help me ?
I can try though I'm a little rusty on Heat Transfer.
@@Freeball99 thank you very much for your answer, i have resolved it .
How can we calculate error when we do not the actual answer? If we know the actual answer why do we need to run FE code?
We can calculate the maximum possible error without actually knowing the measurement. If I have a stopwatch that measures times within 0.1s, then I know my accuracy is within 0.1s - even without having measured the duration of an event.
