Hi I want to model a cube with periodic boundary conditions and uniaxial tension. I need to apply the following equation as boundary conditions to each two surfaces. For example for the right and left surfaces it is like this: U_left=U_right+U_masterNode where master node is a node in the corner of the left surface. I would really appreciate if someone could tell me how to couple the difference in the displacement of two surfaces with the displacement of a node?
