CONTACT IN OPTISTRUCT

NoorAlam_08

Hi Everyone

 

i am doing pretension test in optistruct, and i have applied torque on nut using moment card.i have applied contact between nut(master) and another surface where i want to simulate the result(slave).but in optistruct contact interface there is three type of contact 1.SLIDE, 2.STICK and 3.FREEZE.I Have applied all three type of contact and i got different result. i have problem to which contact should i apply to simulate torque analysis.please let me know which type of contact should i use.and where should i used all type of contacts.

 

Regards
