Difficulty generating periodic meshes
Hi, we would like to ask for some support regarding the use of Gmsh to mesh representative volume elements (RVEs) containing elipsoidal particles, more specifically in the enforcement of periodic boundary conditions.
Using the GUI functionality of Gmsh the problem seems to be that despite the surfaces being well paired through the API, the subsequent pairing between lines inside Gmsh fails to achieve the correct pairing.
In the screenshot below, we can see that Line 502 is paired to BSpline 538, despite the surfaces paired being the ones containing the curves 453, 502 and 504.

The script containing the calls to the Gmsh Python API and the Gmsh output are also attached.
Thank you in advance!
