2D Contact Problem In AINDA84
ADINA84 is an open source code which can solve contact problem.
My model is shown in the picture below:
Pipeline and seabed are both 2D 2-node beam element and seabed is rigid surface.
I define one contact pair,two contact surface and each surface has 99 nodes .Two surface's nodes have same coordinate.
The program'erro is"CONDITIONS OF CONTACT INADMISSIBLE DUE TO DETECTION OF GROSS OVERLAP".
Who can tell me the reason?
One of my friends told me that ADINA84 can only do node-node contact.It's right or not?
I’m beginner in FEM,Any materials can help me to read this program?
