I will try that but I am just assuming that long thin triangular faces would not be such a problem with FEA, is this face that tapers to the cyclic rotation center line the badly shaped element you see
:
- The elements are 4 noded Tetrahedral elements. Looking at the triangle on the surface it looks good but the third dimension is very short. Ideally, you want an aspect ratio one to one. Meaning the ration between the longest edge and the shortest edge is 1. In areas of interest I like to have at least a 5:1 ratio and in other areas it could be up to 20:1. Pretty much all of your disk is critical and the first element has an aspect ratio of roughly 50:1.

I think @ggiraldo and I are still agreeing. Think of it this way. Before any loads or physical contacts are applied you want your model to be stable. The bottom portion of your press is Fixed so it’s not going to move on its own. The coin has two sides that are constrained so it is only free to move in Z. Adding the Elastic Support in Z will keep the coin stable until the physical contacts start to engage. The top part of your press is the same as the coin. Because of the two constraints it can only move in Z. Adding the elastic support will hold it into position for the initial calculation. The top elastic support is probably not needed is all scenarios but it can help rule out some issues.

In your model you have the bottom press part fixed, contact defined between the coin and the bottom press, and then you have the bottom of the coin fixed in Z. In this setup you are never engaging the physical contact or the entire bottom part.

The spring support is also spring to ground connection. You want the springs to be strong enough to hold the part but not strong enough to affect the stiffness. If the spring is not strong enough, when you apply a force, the coin could move too far into the bottom press that the software can not figure out the contact. If the spring is too strong it will affect your results. Since you not applying a force but a displacement this is not as big as an issue.
The about statement seems to me to conflict with this:
I am confused about the confliction of the above two statements, anyone care to straighten me out 
Doesn’t the Ram movement constrain x/y and force movement in the z direction only 
@cjquijano Thanks for input here
