[Gmsh] Geometry Visibility Setting in GUI

[Aaron Kiefer]

GMSH Family,

I'm hunting around for the proper menu feature and/or command to enable visibility of geometry close to the 3D view.  Currently, when zoomed, the model disappears ? (see attached)

Thanks,

Now, I want to apply periodic boundary conditions in x, and y direction and in order to do that I need the mesh to be identical for the x=0 and x=xmax surfaces, as well as for the y=0 and y=ymax surfaces. It is not sufficient for only the nodes to match but I also want the edges to match!

The Periodic meshing command only apply to unstructured grids. In your case the grid is set structured (meshed by extrusion with the "Layers" option).
