The module lets engineers use pneumatic tire models in simulating vehicle systems. The software derives kinematic quantities, such as slip angle, longitudinal slip, and inclination angle, as optimized computational sequences. These are used by tire models to find tire forces and moments. Optional features let users control how tire slip and rolling radius are calculated and include tire transients through differential equations involving relaxation lengths. The program works with DynaFlexPro/Model-Builder, a GUI for creating models using block diagrams and drop-down menus.
