AutoGEM and Analysis & Design Study give different mesh results

I have a model that I'm trying to run an analysis on but I can not get it to mesh properly. It is a very odd situation because I can mesh it no problem in AutoGEM and view the mesh results with no errors or warnings but when I start the Analysis and it attempts to mesh the model, I get a completely different number of elements in the mesh and errors. I have tried deleting all the existing mesh files, deleted the folders for the Analysis and even copied everything to a new folder and I get the same results....AutoGEM makes 125k elements, Analysis and Design studies makes 105k elements with all of the default options.

Anyone have a clue what could be going on here?

I have tried every combination of the "Elements" options including overriding defaults and disabling it altogether. It makes no difference in the results. However, I have noticed this message whenever I try to run the analysis:

Copying elements from an existing mesh file ...
Element copy failed.  Creo Simulate will automatically remesh.

I think it is a large model, with screws or rivet elements?

I had something like that very many years ago.

After playing around with the geometry I have received a new error message when running the Analysis, but I don't know what it means or how to determine where it is located:

AutoGEM created solids that penetrate the boundaries of volumes
