What is Simpack?
SIMULIA Simpack is a complete software package dedicated to the development and simulation of high-fidelity multibody system virtual prototypes. It provides solutions that cover the needs of individual multibody experts up to large-scale company-wide deployments with hundreds of users.
What sets Simpack apart from other solutions is its reliance on a unique technology for setting up the equations of motion of a system. Therefore, the notable advantages of SIMPACK are the speed and robustness of its solver, surpassing its closest competitors, and its utilization of the latest mathematical techniques to deliver the highest degree of accuracy and reliability.
