In this video I show you how to write the tinyest Finite Element Method (FEM) Python Solver from scratch, in 7 mins.
Like my previous video in which I shown an implicit method, I now show the explicit one.
I'm using Jupyter Notebook for clarity.
The idea here is to obtain simple displacements of a single element loading with a velocity in one of its nodes.
Take into account Plain Strain is supposed to be ez=0 so, it is a scenario with thickness (Z dim) larger than in plane (x and y) dimensions. Plane stress is the opposite. So at the end of this video, thickness should be also coherent.
This video is only a sight of a course I'm preparing.
