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.

Hello Zhao,

The sliding energy and contact force should indicate if the contact  is the issue or not. If the contact  is the issue, try the following:

  • I don't have much experience with forming contacts. But, I would try SOFT=2 (segment based contacts), SBOPT=3, and DEPTH=35. If it does not work better, try the *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE with these settings instead.
  • Reduce the bucket sort frequency.
  • Reduce TSSFAC

 

Let me know how it goes.

 

Reno.
