Micheal, Wout, Ben I am testing a code for the problem of 2D plane stress. I want to impose periodic boundary condition just like u1=3Du2. I mainly consider the post of Ben and Micheal. I don't konw where to call the subroutine for periodic bc. The result considering periodic bc is the same as not considering periodic bc. I don't konw how to do. Maybe The part of code considering periodic bc is wrong. The source code is attached. The example is: 1x1 domain, 10x10 mesh, Quad4, fixed bc on x=3D0, p=3D1 on x=3D1, consider periodic bc of ux with node (0.5,0) and (0.8,0).
