 Multibody System Simulation Software 

FIRST is an advanced Multibody System (MBS) simulation software for the dynamic analysis of lubricated mechanical components. It allows you to generate and simulate extensive 3D models to gain a detailed insight into the dynamical and tribological behaviour of the components.

FIRST is used in a wide range of industrial sectors for dynamic simulations 

FIRST supports you at modeling different types of systems with a variable level of detail,

depending on whether your focus lies on a high precision of the results or short calculation times.
