Nonlinear surface contact

Nonlinear surface contact capability applies to surfaces defined by both solid and shell elements. Surface contact is ideal for large, thin-shell fabrications such as ship, aircraft, and automotive structures. Simulate part-to-part interactions of interlocking components, including press-fits, using surface contact.

With Autodesk Nastran surface contact capabilities, you can:

  • Identify free edges that contact surfaces.
  • Automatically carry out edge-to-face welding.
  • Avoid element congruence, if necessary.
  • Use offsets and gaps between edges and faces.
  • Rapidly mesh complex shell structures.
