Example Wheel-Envelope Input File

The following is an example of a wheel-envelope input file (.wen) that you can use to control a wheel-envelope analysis.
 
Note:  
For wheel-envelope input files, Adams Car ignores columns three through ten: (left and right) lateral force, aligining torque, brake force, and driving force.
