  Currently, the fracture mechanics feature does not support contact elements within the fracture zone: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v221/en/ans_frac/frac_parmcalcrequire.html
  Fracture-parameter calculations based on domain integrations such as stress-intensity factors, J-integral, or material force are not supported when contact elements exist inside the domain. The calculations may become path-dependent unless the contact pressure is negligible.
  As such, it is not possible to prevent crack face interpenetration.

  Thank you for your reply! I was wondering if you are referring to fractures or does this apply to geometries too. I did not grow a fracture, instead my crack is created from my geometry first. Is there any way I can keep the geometry from overlapping?
  Thank You!

  if you're not evaluating fracture parameters, then you can use contact to keep the sides from overlapping. When applying the load, you may need a more refined time step so that the contact and target sides can detect one another properly.
