Working Model 2D is a conceptual design tool that allows you to create simulations that replace vague, time consuming, inaccurate “back of the envelope” calculations.  Working Model 2D has been adopted by thousands of professional engineers to create and analyze real-life mechanical systems.

Working Model 2D includes automatic collision detection and responses for NURBS geometry. Our latest release also includes such popular scripts as Flexbeam, Shear and Bending Moment, and Pin Friction. These scripts have been customized to expand your use of Working Model.

Interactive Physics is a powerful tool for discovery learning and helps students visualize and learn abstract concepts. It develops inquiry skills and physics knowledge by allowing the user to vary nearly any physical parameter (e.g., gravity, force, speed, spring constants) and to measure its effect on nearly any measurable quantity (e.g., position, energy, decibel level).
