FEA simulation of delamination between two layers in a laminate

Hello,

I am trying to simulate the delamination between two layers in a laminate.
I already created the interface layer in ACP.

Also you find attached:
- the mesh of curved laminate extracted from ACP
- the interface layer in red (with crack front)
- the interface delamination surface I am trying to select
- the worksheet i used to create it
- the interface delamination details window, that i am trying to complete.

What is missing in the detail window of interface delamination is to select:

- the source and target faces of the interface layer.

I tried to create a node named selection of the interface layer using worksheet but:

1- this node name selection contains BOTH source and target nodes.

How can select only source Or only target ? Also how can I do to fill the details window ?

PS: In the option Generation Method of the scope paragraph, I can't find the Pre-Generated interface as in the delamination tutorial of ACP advanced!


I willl send you the model in ansys 2023 R2 upon request
