Dear Justin Thanks for your reply.
You are right. I should not extrapolate too literally from your tutorial to my system. But, I have a general question: There is 2 groups in COM pulling method (reference group + pull group). If I want to use pull_geometry = distance, so, I should fix reference group to be immobile. Is it true? On the other hand, I want to know exactly using position restraining on reference group is optional or mandatory in COM pulling method?
