CONTACT Problem
CONTACT Problem
(OP)
HI,
I have some problem when modeling contact with TARGE69 and CONTA175. Target elements are penetrating too much the contact elements when using keyopt(2)=1 (penalty algorithm).
Any suggestion to solve the problem?
Thanks.

RE: CONTACT Problem
Also, I don't know your particular contact algorithm, but I can guess a similar approach is used with this one--many contact algorithms allow the Target to penetrate the Contact Body, but won't allow the Contact Body to penetrate the Target (or vice versa).

RE: CONTACT Problem
Maybe if you try Augmented Lagrange algorithm for the contact it can work.
RE: CONTACT Problem
I am with kemechial, Lagrange could work better. But if the Penalty-Method is mandatory, I would increase the contact stiffness and decrease the step time.
