Hello.  I believe Gmsh's meshing algorithms are random, so even
repeating identically the meshing and saving options might give you a
different mesh.

Ah OK, thank you for your hints. I noticed now that indeed none of the results I sent is deterministic.

However, I can reproduce the exact same .msh file when I do not use the GUI but run the mesher in batch mode:
$ gmsh -3 column.geo

The console output tells me that in both cases (GUI and batch) the same (?) Delaunay algorithm is used. So why does the GUI based approach include a random element, while the batch mode obviously does not? What is the difference between them? Maybe one of the developers can shed some light on that?
