The purple bolt is fixed in all freedoms, use the yellow pin to press the bolt. The pressing head of the yellow pin is sharp, just like the second picture.

At first, no automatic contact control, the calculation doesn't converge.

Then, automatic contact control is added into the contact of these two parts, the calculation converges. But when I check the results, several nodes are found to penetrate into the opposite contact surface. 

Q: How to eliminate this penetration?
