Maplesoft releases high-performance MapleSim 4, a physical modeling and simulation tool, and Maple 14 technical computing software. Both are based on Maplesoft’s symbolic computation engine and physical modeling techniques; together they provide tools for design, modeling, and simulation, including real-time and hardware-in-the-loop applications. MapleSim 4 introduces a 3-D construction feature for developing multibody models. Instant, realistic feedback of multibody systems is provided as the model is built, and engineers can add and manipulate multibody components directly in the 3-D workspace. Other features include flexible probe management tools, a semi-stiff solver, and improved analysis tools. Maple 14 increases depth and breadth of math for engineering applications, including control system design tools, linearization tools, and solvers that allow engineers to apply advanced techniques to control design problems. Updated tools and resources accelerate the work environment and expand connectivity with MATLAB.
