Contact Interface/Mech Help

  Hello,
  
  I am running a simulation that has a pin inserted in a cast steel hole. I have adjusted the geometry to be realistic with the pin sitting on the casting, rather than the two holes being concentric as shown in the image below.
  
  When I run initial contact the information says that the contact is not closed.
  
  What can I do to improve the contact status? I am running frictional type contact.
  
  Thanks.

  In the Details window for that contact, in the Geometric Modification category is the Interface Treatment property.
  
  Set that to Adjust to Touch.

  Peter thanks for the prompt reply.
  
  I have set the Adjust to Touch as you recommended. I have re-run the contact tool to get the status and only a small area of the pin is being picked up in contact, as shown in the figures below (1 in the number contacting.
  
  I was hoping to see a more even distribution of contract status along the underside of the pin to the casting. Can I improve the status further?
