Layers of ball separating at high mesh counts

      I am currently running simulations in ANSYS mechanical that include a multi-layered ball. The simulations run fine at lower mesh counts, but when I hit a specific number of divisions on the edges of the ball layers, the layers are separating upon contact with the other surface in the model. As I said the model works good below this specific number, so I know that the contacts are defined properly. Has anybody experienced this or have any suggestions? Thanks

      I am sorry, but the issue is not very clear from the images. Can you please post a cross-section of the geometry as well as the mesh? The images that you ave posted seem like of a result.


      Which mesh method are you using? Are you using any element delete operations?
