I don't know if I ever put the code online, but I did something similar a few years back for a bow deflection solver using Hooke's law and finite elements. I was planning to solve for arrow speed as well but never got around to it. I've kept the technique in my box of tools, though, because it's conceptually simpler for me to set up an optimization problem than it is an ode solver. Very cool write up.
