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

[@davidgonzaleznino5914]

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:

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!!

Very helpful tutorial

[@visible871]

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?.

Hey! How can I ask for a Triangular meshing?

[@amirmohamadbalizadeh473]

Hi great video as always... I know its irelevenet but can u suggest a refrence for learning uel subroutin and its implementation in abaqus

[@engineering_software]

I will publish a video for it. But I guess not soon. So please send an email to us to send you some files.
