Computer simulation of vehicle dynamics has become a valuable tool in the design of vehicles. However it is unable to simulate the complex dynamics of fluid sloshing in a tank on the vehicle. Computational Fluid Dynamics CFD analysis software is available that can predict fluid slosh however it does not facilitate computation of the vehicles mechanical system. This is the second phase of a multiphase program to develop and demonstrate the use of CFD analysis coupled with vehicle dynamics analysis to more accurately predict the dynamics of a fluid transport system. The first phase validated that CFD analysis predicts slosh dynamics of a tank subjected to motions of a vehicle encountering typical maneuvers. The results of this study phase 2 demonstrated the successful development of subroutines that are integrated into vehicle dynamic and CFD simulation codes.
