Hey Malbaro,

ANSYS uses a Force Convergence Tolerance of 0.5% to stop iterating. That is acceptable for most models.

If you want a smaller Force Convergence Tolerance, type in a smaller value, such as 0.01%

I recommend using a smaller tolerance for the Displacement tolerance also, like 100 times smaller.

You can also reduce the Contact Penetration tolerance.

After meshing, the geometry that was tangent now has small gaps of different sizes. When you use Adjust to Touch, that moves surfaces around differently for each of the six contacts. It would be better to move them all by a constant offset. I used an offset of 8.3e-4 mm which closed the 6 contacts.

Here is what I got with the above methods... +/- 0.0038 N

If you cut the three pins off the center body, you could mesh them with a regular swept mesh, which would reduce some of the variation. If you replaced the spheres with crossed cylinders, you would reduce the mesh variation even further.
