It is suitable for anyone interested in learning 3D CAD and Motion Simulation for free before upgrading to commercial packages. Educators will find it ideal for the teaching of dynamics, machine design and physics. It is a freeware which is sponsor supported. The parts are 3D solids, which can be connected by joints, constraints, contacts, actuators, springs, dampers, forces or torques. Animation using the simulated data produces realistic behavior of the system under study.
Users can also obtain engineering data in the form of plots and tabular output.
Data series available include linear and angular displacements, velocities, accelerations, forces, torques, momenta and kinetic energies. Acceleration data include transverse, centripetal and Coriollis accelerations. Users can view forces and torques from joints, constraints, actuators, springs, dampers, applied forces and inertia. This is a major release which contains numerous enhancements and bugfixes from the 18b release. It mainly conforms to the ANSI Common Lisp standard.
