Dear Gmsh developers, I have recently moved from Gmsh 3.0.6 to the most recent 4.3.0, and I have noticed that the .msh files for extruded meshes with layers are slightly different than before, because they contain periodicity relations. To me this is puzzling, because I do not have any periodic mesh. Why are the periodicity relations written even on non-periodic meshes? is there a way to turn this off?
Second, I have noticed that Gmsh is returning an error when reading these .msh files. I have attached two meshes (2D and 3D) that prove this: the .msh files have been generated from the attached .geo ones. For example, when I open square.msh, I get "Error: Cannot find periodic counterpart of vertex 3 on edge 2 nor on 2". Since these are two extremely simple meshes, I was wondering whether there is a bug in the definition of the periodicity relations, or whether some commands I am using need to be changed with the new Gmsh version. For your information, I have to use the MSH 2.2 format for compatibility with my CFD code. Thanks.
