This is a demonstration of the dynamic simulation and finite element analysis (FEA) environments in Autodesk Inventor 2011. I modernized a trebuchet to show some of the capabilities built into Autodesk Inventor. The demonstration shows how to do basic FEA, then I set up a dynamic simulation that launches a projectile from the system, and follow that up with another FEA using the motion loads generated by the simulation.
