modelise the motion of the fluid by a moving wall
 

hi all. i have a horizontal cylindre whith pressure inlet and pressure outlet in top and a water liquid is filled in the half of the cylinder, we create the motion of the fluid using a plunger defined by moving wall in the left of the cylinder. my problem is how to define the velocity of the moving wall (0.01m/s)by initialising on boundary conditions or defining custom field function or using UDF.
