Dear Sean,
For this course (and maybe for other courses as well) it’s better to not do this for solving the stiffness matrix:
“U = Ks.I.dot(forceVector_red)”
Do this instead:
“U = numpy.linalg.solve(Ks, forceVector_red)”
For bigger structures with much more degrees of freedom, it will be much faster in solving.
the linalg.solve() function doesn’t have to calculate the inverse of a matrix which makes it faster.

Great Yannick - thanks for that tip!
