Hi
I've been trying to simulate a pull test on a carabiner I've modelled.
I added fixed constraints, no penetration (between the pulleys and carabiner) and the force (7000kN total).
See below:

The carabiner twists, I'm not sure that is how it would react.
During the test a 'large displacement' popup appeared. I tried clicking both yes and no, the yes failed and the no gave me the results above.
The pulleys have a tangent mate to the carabiner and parallel to planes.
Have I set up the test correctly? How else could I try this test?
I would simplify this simulation with just the carbiner. Use a sketch to split the face (parting line) at the assumed contact area on both sides. I would then set the top face as a fixed surface and apply the force fully on the bottom split face.

I swore I posted that days ago. Let me know if this helps.
shaw600,
Are the pulleys (u shaped pieces) constrained so that their vertical axes parallel to the force are always aligned? This is the case in the real world. You would never get the displacement out of alignment with the force that shows in your attachment. I would constrain the pulleys so their axes are aligned. They should be able to twist about that axis, but not out of alignment with it. That way the beaner could still twist, but the forces will still be aligned.
