Hello Peter, I did a simulation to obtain the homogenized properties of a UD RVE. XTension case comes out like so, with the edges pulled farther out than the other parts of the XFront. I feel something is not right as Abaqus gave different results both in deformation and values.
Used a roller boundary condition on each of the opposite sides. Xback, Ybase and Zback. Then I created a remote point a small distance away from Xfront for XTension case. Finally, some constraint equations to link the remote displacement to the Xfront.
THE ISSUE IS THAT THE EXTENSION I GOT HERE HAS A TOTALLY DIFFERENT RESULT FROM WHAT I OBTAINED FROM ABAQUS BOTH QUANTITATIVELY AND IN GRAPHICS. THE GRAPHICS IN ANSYS, AS SEEN IN THE ATTACHMENT, IS EXTENDED OR FRAYED MORE AROUND THE EDGES THAT THE MIDDLE PART. I FIND THIS UNDESIRABLE. PLEASE HELP

Thanks, it's asking for lower and higher boundary selections and some length in the preceding form.
