Hello everybody,

there is a tutorial about czm delamination in ansys help and there is a 2D geometry to download. Does anyone know how the contact region can be created?

Here is a link to the tutorial. https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v195/mech_tut/ds_tutorial_debonding.html

Here are the instructions for how to use the URL for the tutorial.

The tutorial shows how to create the contact region.

There is also a YouTube video that shows how to create the contact region.

What part of creating the contact region do you need help with?

Hello Sir thank you for your response.
I tried to draw my own geometry with designmodeler. I have repeated all construction, which be used in the geometry from ansys file ( geometry like the video you posted). By editing the model schould be seen a contaction with (+) in the tree on the right( by using ansys file appears connection with (+ symbol) automatically). By using my file (self drawing geometry with same constructions in ansys file) the connection appears with out (+) that is mean by defining the region no low and high geometry been seen or created.
The second 0.28 shows green and red lines hier schould be the conact region in designmodeler already defined
That's my problem hope good understandable.
Best regards

Please insert images from screen snapshots of your geometry in DesignModeler.

Do you have a vertex along the bottom of the first body?

Did you mirror that body to get a second body?

Good Afternoon and thank you for your response.

maybe the matter with vertex . Would you like to tell me how to creat it?

When you are sketching, use two lines on the bottom of the top part, not one long line.

hello Sir,

i have used 2 line , but still no conection by importing in Workbench. Pease see the image below

it should be like the Image number 3 when i use geometry file from ansys

The screen snapshots have huge blank white borders below and to the right. That is a waste of space. Please find a screen snapshot tool that does not do that. The Snipping Tool included in Windows 10 doesn't do that. Neither does Greenshot.

If you right mouse button click on the Connections folder, you can Insert a Manual Contact Region. Then you can pick the edge of the top and the bottom part to create the bonded contact.

Note that you must have set Shared Topology to None in DesignModeler. If you did not, then there is only one edge and it is shared by the top and bottom surfaces so you will not be able to define a Bonded Contact.
