Getting Started Tutorials
Select Adams Help from the Help menu then navigate to the getting started
section. Though the demo vehicle appear much more elaborate than the
FSAE model, they are actually very similar, and the Getting Started tutorials
are directly applicable to the FSAE template for the most part.
