• 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

The storage area for the trunk is composed of

3 planes with limited size

declivities, alternating side slope and small scale

bumps that rock it side to side. The tractor and trailer

must negotiate a fairly tight turn with slope LMS Amesim
