multiple pretension to one screw

Altair Forum User

Hello

I wanted to put two different pretensions on one screw (solid) one after the other.
During calculation, the screw is torn at one of the two contact surfaces.

I use two contact surfaces (one for each pretension).
When I try to apply two pretensions to one contact surface, I get the ERROR # 2318
If I place two contact surfaces on the same elements, I get the ERROR # 2324
