Is there any way to set a variable for initial conditions of joints that have been applied motion in adams solver script (.acf)?

s.kuris
Here is the example of my simulation script.
I would like to set a variable for ICDISP.
 
MOTION/4,JOINT=14,TRANSLATION,VELOCITY,ICDISP=-25,FUNCTION=0
MOTION/3,JOINT=12,ROTATION,VELOCITY,ICDISP=2.532d,FUNCTION=0
SIM/KIN, END=2, STEPS=360
MOTION/4,JOINT=14,TRANSLATION,VELOCITY,ICDISP=-25,FUNCTION=0
MOTION/3,JOINT=12,ROTATION,VELOCITY,ICDISP=0d,FUNCTION=0

    Yeah, I did that study around 31 years ago Grinning
    It is easier to parameterize the model in the correct way and run the optimization directly in View.
    It is a little pickling to get the parameterization of the hooke joints and clocking angle correct, but once it is done, you have a model with a couple of hardpoints (2, 3 or 4 depending on how you want to work with the model) that you can move + one variable for clocking angle to change. Then I typically run one revolution (on the steering wheel) with constant angular velocity and has an objective for max variation of the angular velocity of the output shaft.
