Any tips for surface to solid contact in Marc

cameron.plantz1
I'm familiar with Apex but still getting used to Marc. I have midsurfaced and surfaced meshed a part in Apex and will have it contact a solid (similar to a bolt going through a plate). Are there any tips to get more realistic results? I've already seeded the contact area for node to node contact. This will be a nonlinear analysis looking at the failure modes of the interaction.

    Dear Cameron Plantz,
     
    You can define the shell body as one contact body and the solid body as another contact body. Define a contact interaction with either Touching or Glue contact and then define a contact table and chose appropriate contact interactions between the bodies. This approach is similar to Nasran style of defining contact bodies, contact pair and then contact table. Then the contact table has to be called in a loadcase.
    It is not mandatory to define the contact interaction and contact table, if there are only two bodies which will be in touching contact, then if you define the contact bodies it is sufficient.
    Node to segment and segment to segment contact both will work.
     
    There are many examples in Marc User's guide on contacts. I am attaching one simple contact example for reference.
