In group you are applying to a group of entities, right?

Hi,
I think you are applying more pretension with the group and less with the individual.

@Prakash Pagadala Thanks for your reply.
But I have do the simple test, it will separate.
When I used this idea in full model it can't average.
Why?

HI,
I am sorry but did it average?
How is the pretension applied in both cases?

@Prakash Pagadala Thanks to your apply.
Because I see it contact force is the same so I think it is average.
At the other pretension I also use the total force to let it average to the other bolts.

I will investigate on a sample model and will share the results.
