Overview
...
The BodyForce helper object Body Force produces a force toward a geometry object that can be used for giving shape to the fluid. The force is pronounced outside the body, but the inside is replaced with a mechanism that suppresses the fluid's escape.

You can set the Strength parameter to a negative value so the fluid gets repelled by the body. |
Maximal Maximum Distance (units) | maxdistunits – Specifies the distance at which the force disappears. Note: This value can be animated when needed.
Fade Start | fadestart – Specifies the relative distance (as part of the Maximal Maximum Distance) where the force starts to weaken.
...
Internal Damp | internaldamp – Specifies the amount of damping applied to velocities inside the body that are above the Damp Min Vel. threshold. This parameter is used to prevent the escape of the fluid from the body. If this value is set to 0, the fluid attracted to the body will pass right through the body, then it will be attracted back towards the body, pass through it again in the opposite direction and so on. This parameter is not affected by the Strength of the Body Force.
Damp Min Vel. (units/sec) | dampminvelunits – The fluid velocity above which the Internal damp force works. This parameter allows slower fluid to keep moving without being damped. It does not affect the Spread Speed.
Spread Speed (units/sec) | insidespreadingunits – Specifies the rate at which the fluid fills an object's volume evenly, in world units per second. This parameter is not affected by the Strength of the Body Force.
