How do you model the liquid sloshing ? Do you use an Arbitrary Eulerian-Lagragian (ALE) approach ? I do not know how to program it in Fluent but I know that is a benchmark case of COMSOL Multiphysics, which couple the Navier-Stokes equation with an ALE equation.

I hope it helps

Due to movement of the vehicle, liquid in tank would experiences a pseudo force. The force can be calculated due to contribution from both linear acceleration and angular acceleration and can be supplied as a momentum source term to FLUENT.
