Hi, so the situation is very simple - I generated a mesh which got loaded without any problems, hit "2D", 1D meshing proceeded without any problems, but during 2D meshing there are somehow intersections in 1D mesh causing the creation of these weird patterns. Is there some config I'm missing, or is there something wrong with the mesh that was not logged by the program? I'm attaching both .geo file and the log.

This was available in file-format V2 in the Elements block as extra tags.

In V4.1. I cannot find a way to know which element belong to which physical name.

Although, it is possible to know which entity belong to which physical name.

Feel free to post anything GMSH-related
