The curve-curve contact allows liftoffs and collisions based on coefficient of restitution. Available actuators are rotary and translational. Their motions are linear functions of time. Spring-dampers accept offset, linear stiffness and linear damping. Applied action-reactions are linear functions of time.
Available torques are similar.
Users can specify constant gravity of arbitrary magnitude and direction. Users need to provide the domain to simulate the behavior of the system. Simulation progress can be animated and stopped any time. After simulation, the computed solution can be used for animation or frame by frame analysis. Full 3D pan, zoom, tilt and rotate is available during simulation and animation.
