- In this video I simulate and animate a 3D spinning top by solving Lagrange's equations in python, and animating the spinning top in Matlab.

So, is this like a gaming channel for solving differential equations? As an instructor for ODEs I really appreciate that you are stepping up the challenge for all of us. Great job!
Man I like your tutorials. Want to binge watching soon. Wish me luck. All the best for your channel.
this is so cool, your videos are seriously valuable keep it up man
Hey man, I am a mechanical engineer from Brazil, and this content is awesome.
Hi Mr, I study physics in UBA (Argentina) and I'm new in the channel, your videos are great!
Really nice stuff, Mr P Solver! I was just wondering if it was possible to implement this animation in Blender, maybe by exporting the data containing the solution and key-framing a spinning top modeled in Blender.
Another question: have you ever wondered about using Blender and all its shiny, glossy and nodes-editor features to visualize your data?
Once more, thank you so much for this huge inspiration and all the nice content!
Very nice lecture, informative and clear. A minor comment is that omega $\vec \omega $ is the angular velocity, not the angular momentum, given by $I \vec \omega$
Watching your video regularly,can you please make video on epicycle drawing details on python
when I used this
sols = smp.solve([LE1, LE2, LE3], (the_dd, phi_dd, psi_dd),
simplify=False, rational=False)
and
sols[the_dd]
it continues to run for more than 1 hour and it did not stop!
thanks
You probably need an earlier version of sympy! Try installing version 1.6. For some reason there is a bug in the newer versions
@@MrPSolver I have also this problem, and when I try to install sympy version 1.6, anaconda asks for python 3.6, which I can't install because there is conflict with almost all the libreries I have installed. What do you suggest I should do?
Same issue for me. Solved by installing version 1.6. of sympy! Now it takes only 3 sec. Weird Bug!
@@oriolpelegriartola6019 try creating a new environnement with python 3.6, some of the libraries might still work
It doesn't work for me I get TypeError: can't convert expression to float in the odeint function. anyone know how to fix this?
Great content. How about using fenics as pde silver?
I've been looking into this. It's a steep learning curve but definitely something for the future.
Same problem as with the 3D-Pendulum.
The expressions sympy.solve([LE1, LE2, LE3], (the_dd, phi_dd, psi_dd), simplify=False, rational=False)
is expected to tackle are soo long that the process of finding a symbolic solution was shown to take seemingly forever.
Are you using a professional version of Python implementing precompiled code capable of streamlining the process perhaps?
You are also doing something rather unorthodox here: sols[the_dd]
namely, indexing with a symbolic expression of the 2nd derivative of Theta, rather than an Integer commonly used for slicing. 😭
I imported the code and it is stuck at this line forever...
Now do it using quaternions 😩
Your videos are awesome. My sadness is that I don't understand English perfectly, but with patience I'll understand. I'm trying to understand the code "R@smp.Matrix([0,0,1])". What does this "@" mean?
It’s matrix multiplication in Python
You are a carbon copy of elon musk man. I am from India and I am great fund of your tutorial.
