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.4
