I applied some mesh controls, lets see if this helps
looks like you could get away with 2d symmetry and then half the model. what am i missing?
do you really need the no pen contact? are you sure you can't get an overall behavior with the components assumed as bonded?
if you're analyzing the wheel and not the spring, why not replace the spring with an idealized spring? or why do they have to be analyzed together?
I was able to add tiny gaps in between layers to avoid using contacts. I compared a simplified version, one with the gaps and one with contacts. The results where the same.
And that image above is not the spring. The spring is a series of concentric ovals. These are the spokes of the "Wheel" and are offset in a way that 2-d would not work.
but it worked, thanks for your response
