Hello, I have been trying to model the mode-II ENF test over the past month but every time I am facing some issues. I have archived my simulation in the link below, I will be very grateful if someone can guide me to what I should do to get this right. Thank you.

Hi,

Ansys employees cannot look into the model but please wait for other forum members to chime in.

Thank you for your reply, I am getting this warning message everytime. I am not sure if this is the reason that the problem persists. 

*** WARNING ***                         CP =      79.031   TIME= 10:49:35
 Fracture parameter calculation issue: crack tip node is attached to     
 element type that is not supported, Crack 1, crack tip node 81756,      
 element type 170.  The element is ignored.

This problem has been discssed in previous threads but the soution proposed there does not work for me as I have generated the pre-crack in ACP-Pre and I can only access that surface through "Pre-Generated interface" options in the contact settings.

Hello,

Did you refer to the following thread?

The fracture parameters computed during solution may be incorrect (ansys.com)

Yes, in my case the interface is modelled in ACP-Pre during modelling the plies. So the only way I can properly access the pre-crack and bonded interface is through Pre-Generated interface option in the scoping method while defining a frictionless contact for my pre-crack.
