Is it possible to use a motion UDF as an input parameter?

  Hi there,
  I'm doing a 2D axisymmetric analysis of the damping coefficient of a piston. I am using a dynamic mesh (layering) to capture the movement of the piston head. Therefore, I require a motion UDF/profile to prescribe a velocity to each side of the piston. I would like to conduct a parameter study on the velocity of the piston but I am unsure whether it's possible to parameterise the motion UDF/profile. If anyone could enlighten me on this subject, that would be great :)
  
  Thanks in advance

  If you need to code up damping then I suspect you want a UDF. In which case parameters aren't really an option as you will need to edit the code.
