We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi, I think the program controlled settings work best for the contacts. However, if you still see some penetration try giving contact sizing and try refining the mesh in the contact surfaces.

If these contact settings wouldn't work i will go with:

  1. Contact formulation : Augmented Lagrange
  2. Detection Method: Nodal Normal to target
  3. Penetration tolerance turned on with low value of tolerance 
  4. stiffness : Factor
  5. Stiffness factor: if both clip and plane are same material Use 1 if one material is soft use 1e-2
  6. update stiffness: Each Iteration
  7. Pinball radius : Program Controlled
  8. Interface Treatment : add offset, No ramping
