Hi Guys,

I am a bit new to APDL and trying to model layered soil system in APDL. How can define contact (simple bonded or etc) in a 2D layered soil system. Maybe for following extremely simple example...

 

Thank you in advanced

The Ansys help is very comprehensive in explaining all things contact. In APDL you can obviously script all your contact needs, but there is also the contact manager and contact wizard for managing and creating contacts. To access the contact manager there is a button in the top toolbar. Once the contact manager is open the first button on the left is the contact wizard. You can define contacts through GUI selections or pre-defined components with the contact wizard.

Hi Mr Starling,

Thank you very much for your answer, it is really helpful.

I have a question. As per the above very simple diagram. in a 2D layered soil system. this contact (contact between soil layers) should be surface to surface or line to line?

Thank you very much again

Have great start in the new year 2020

This contact is defined as surface to surface. It is a line shape element though. You can check your model by confirming the contact elements that are created. You should see Contact 172 elements defined.
