Hi, I tried the method you suggested. It restricted deflection beyond the metal surface but unfortunately it started with that area in contact. I need the tongue to deflect during insertion but the tongue shouldn't cross boundaries. My apologies, I should have mentioned this at the start of this discussion. I found following result.


The yellow (bow shape) marked is undesirable, Green and Red faces were taken to be in contact. I need to take edge contact for green and face contact for red but it seems it will give similar result. Should I add another manual contact along with previous ones ?

Thanks. Any suggestion is most welcome.
