Introduction to the 3D animation in LMS Amesim
Piston and cam Vehicle dynamicsValveSynchronizer
• What is the 3D animation?
The 3D animation is an “analysis tool” to help users to observe their system behaviors dynamically in
a 3D scene depending on the computed results of the simulation
• It mainly focuses on the motions (displacement, velocity, …) but the tool is flexible enough to observe
any dynamic variables such as gradient of pressures, gradient of temperatures, …
• It’s fully integrated in LMS Amesim
