Reply To: Can I create bonded/rough contact between two surface with slight gap in between

[Nanda Veralla]

Hello Sushant,

Can you try exploring some contact settings? We recommend using the "Adjust to touch" setting under the geometric modification feature.

Adjust to touch: Any initial gaps are closed and any initial penetration is ignored creating an initial stress-free state. Contact pairs are "just touching". This setting is useful to ensure initial contact occurs even if any gaps are present (as long as they are within the pinball region). Without this setting, the bodies may fly apart if any initial gaps exist or might lead to convergence issues similar to what you're experiencing.

Please let us know if this didn't help.

Nanda.
