GRAVITY - Add gravity body forces

GRAVITY xc yc zc gx gy gz

The GRAVITY keyword allows the user to include the effects of gravity on the fluid.

    xc, yc, zc   Coordinates of a point on the "ground" plane (normal to the gravity vector) used to define the location of zero potential energy, in grid units
gx, gy, gz Components of the gravity vector, in ft/sec2. For example, if the y direction is normal to the earth's surface, these values might be 0.0, −32.2, 0.0.

This keyword cannot be used with the Van Leer differencing scheme (RHS VANLEER).
