LMS Virtual.Lab Motion is specifically designed to simulate realistic motion and loads of mechanical systems. It offers effective ways to quickly create and refine multi-body models, efficiently re-use CAD and FE (Finite Element) models and perform fast iterative simulations to assess the performance of multiple design alternatives. Engineers can use its scalable models to execute conceptual kinematic studies at the earliest stages of development, and integrate test data and run more detailed assessments at subsequent stages. Motion results can easily be used to drive subsequent analyses in LMS Virtual.Lab in order to perform concurrent cross-attribute optimisations.
