When choosing a tool to simulate their products, engineers want something that will deliver consistent results from the very beginning of the design process to the end of production. SIMULIA’s Simpack product suite offers this kind of end-to-end reliability. The Multibody System Simulation (MBS) software is used for the dynamic analysis of any mechanical or mechatronic system in time or frequency domain. Engineers who use Simpack can generate and solve 3D virtual models in order to predict and visualize motion, surface velocities, accelerations, coupling forces and stresses.
The 2021 version of Simpack was released recently, with a variety of new functionalities added. Some of the new features include:
General Functionality
- Deprecate OLicense Server support (support to be withdrawn in the following release)
- Automatic front/backplane clipping adaption during animation (Simpack Pre)
Simpack Solver
