modeling of slosh analysis with time varying accel/decell

I am trying to model some sloshing analysis in a fuel tank of an marine engine. I want to give accel/decel which is varying with time.
In reference values i was able to give constant accel/decel but not varying. I will be thankful if some one can provide me solution.

1. very easy method - simply type an equation into the gravity setting for X (ie replace 0 with say sin($Time * 3.2) or whatever.
2. easy method - create a field function called say GravX, and set its value to the required equation -
eg sin($Time * 3.2). Then simply type this field function name into the gravity setting for X (ie replace 0 with $GravX).
Even thought lots of menus dont have a field function dropdown and only constant settings, you can still type in a field function name or equation - very handy and not well documented!
3. harder method - do a java macro and solve via the macro changing the gravity constants every timestep.
