How Are Research Products Integrated?
New PowerSim simulation results computed off-line
• View motions with ArcSim animator
• View plots and overlays with WinEP (ArcSim plotter)
New inputs and parameters generated off-line
• Run ArcSim models with worst-case steering and
braking inputs
• Run ArcSim models with new tire data
Run new simulation programs
• Proper handling models
• Alternate equation formulations
