ear Gmsh developers and users,I have been routinely using the very nice feature of Gmsh that allows to define periodic surfaces and exactly the same meshes at opposite sides of the domain.
However, trying to define the geometry with splines, I have stumbled on a weird problem. The Gmsh software spits out error about not finding periodic counterpart of edge, while meshing in 1D does not complain about anything (see attached example.log). The corresponding GEO file is also attached. I am meshing the domain using command line call
gmsh -3 example.geoI use version 2.16.0, I have checked that 2.12 produces the same outcome. After the error message, the Gmsh crashes with segmentation fault for me.
I have tried removing the Periodic definition for the problematic surface and then everything works absolutely fine.
Do you have any suggestions or could you point me in any direction, which could solve this problem?
Best Regards, Ugis Lacis
