Junaid, 


Try the following:



  • Change the Normal stiffness from program controlled and use a factor of 5 or 10 even. If needed, change update stiffness to Each iteration.

  • Change the formulation from Augmented-Lagrange to Normal-Lagrange. This will eliminate nearly any penetration, but make sure that you are using the direct solver in the analysis settings.

  • Lastly, as Peter suggested, use a higher pinball radius by changing it from program controlled to manual and make sure that the contact regions are being properly closed by the blue transparent guide ball that shows up.
