Fluid Body

Fluid Body properties have to be updated in order to define the movement of the cylinder as shown in Figure 121.

When any Displacement Options field is defined as Fix, the correspondient Displacement Values field will be used to define the displacement of the Fluid Body every time step. In our case a displacement of -1.0*t means that the cylinder is moving forward with a velocity of 1.0 m/s.
