MBS vs FEM: Differences Explained for PF Users

[abaqus]

Hello PF Users!

First of all spent a good time at forum.

I'm a newbie about this topics but i wonder why we need MBS (Multibody Simulation) Simpack, Adams etc.?

Why the FEM programs don't fullfill the MBS capabilities?

Best regards,

userMultibody simulation (MBS) is used to simulate the motion and interaction of multiple rigid bodies in a system. FEM programs, on the other hand, are used to simulate the behavior of deformable materials in a system. As such, FEM programs are not suited for MBS applications since they cannot accurately model the motion of rigid bodies. Simpack, Adams, and other MBS software are specifically designed to capture the motion and interaction of multiple rigid bodies.
