A fully functional free Dynamic Simulation Software. Mechanisms are represented by connected or assembled joints of 3D solids with defined constraints, actuators, springs, dampers or forces. In addition to pure geometric and connection information, mass, moment of inertia, gravity, force and torque information are also modeled and used to predict the motion according to Newton's Laws.
Animation using the simulated data produces realistic dynamic behaviour of the system under study.
An excellent program that offers solutions to user specifications rather as against the old painful approach of trying to find out the right mechanism that works.
