Retaining wall

Post by partla » Tue Nov 06, 2012 9:53 pm

Hi,

I’m trying to model a retaining wall and I want to use zero length elements with a parallel material (an elastic no tension material parallel with a viscous material) as interface elements between wall and soil elements. I use quadrilateral elements for soil and elastic beam column elements for wall. I know thatin this model there are two types of domains, the two-DOF domain where the quad elements and their respective nodes have been created, and the three-DOF domain where the wall elements and their respective nodes have been created.
In order for the two domains to be connected, I use equalDOFcommand to connect nodes on the common boundaries of the two domains. But I got a warning. The warning is that “ nodes … and … have differing dof at ends for Zerolength … “.
In your idea what’s the problem? How can I fix it?

Thanks in advance
