In the detailed opening you can modify the open ratio of the crack (4 different openings you can add), have you try with this ?

Correction. The temperature limits are schedules. You don't have to change them with EMS...they can stay set. I was looking at velocity modulation.

I don't think there is a way to change the opening area with a schedule directly. The only way that I can think of is to use the temperature scheme and change the temperature limits via EMS...I looked into this a while ago, due to another problem I was having. The problem was solved without imploying the EMS so I didn't have to complete it...VERY time consuming to do this at zone level.
