Applying periodic boundary condition (PBC) to RVE by Python, Part I: mesh

In this video after a summery about the periodic boundary condition, PBC, the basic of creating nodes and node pairs for PBC is explained. Creating appropriate mesh for PBC is explained both in Abaqus environment and by python scripting. Then node pairs are created both by hand and automatically by python.

    Thanks for this amazing video! It has been really helpful! I have a question, what do you use as Node_Tol @ 9:26? What criteria do you use to establish a Node_Tol? Thanks and good luck!

    Tol is less than a few percent of the element size. By the way please check this plug-in: kzread.info/dash/bejne/a5yetaaInMnSl9Y.htmlsi=XxAie3FJQLjYSPSQ and also check our website for scripts: www.engssoft.com/

    Hi, just what I was looking for. Your RVE has a single edge for left, right, bottom and top each but my RVE (a brick and mortar model) has split edges for the left and right side, i.e., 6 small fragments constitute the left and right edge each. How do I modify lines 40 and 41 in your code so it works for me? As the top and bottom edge is a single edge for me, i tried using ur code for it. ABAQUS generated the sets containing individual nodes but they are of type 'Node+Element' and I cannot use them in the constraint dialog box. Later I tried keeping Left Edge = e.findAt(*All the edge fragmenst*) and then EdLe = e[q3:q3+1] but when I run the script it shows typeError: unsupported operand type(s) for +: 'AbaqusMethod' and 'int' Thanks in advance!!

    Hey! How can I ask for a Triangular meshing?

    Thanks for this great video, I want to ask that In the case of 3D RVE for edges to generate node pair we can use the procedure you suggested but how can create node pairs on opposite faces, in the case of 3D-RVE?.
