Autodesk Simulation software provides a broad range of mechanical simulation tools to help designers and engineers make critical decisions earlier in the design process. With extensive finite element modeling tools and built-in material libraries, you can study initial design intent and accurately simulate the behavior of a digital prototype. Autodesk Simulation software supports direct, associative data exchange with most CAD software tools, so you can make iterative design changes without redefining simulation data. By helping you predict product performance, including situations in which multiple physical factors interact simultaneously, Autodesk Simulation software helps you validate and optimize designs before manufacturing.
