You can extrude the surface and remove the volume obtained in order to
take into account
the other elements inside your 3D cube.
E.g.:
Point(1)={0,0,0};
Point(2)={1,0,0};
Point(3)={1,1,0};
Point(4)={0,1,0};
Line(1) = {1,2};
Line(2) = {2,3};
Line(3) = {3,4};
Line(4) = {4,1};
Line Loop(1) = {1,2,3,4};
Plane Surface(1)={1};
vol[]=Extrude{0,0,1}{Surface{1};};
Delete {Volume{vol[1]};}
The two surfaces on xy planes have the same mesh.

Hello,
I am trying to create a 3-D cube mesh, such that the opposite faces
along x and y directions have identical surface meshes, which will be
useful for me to implement periodic boundary conditions. Is there a
way to do this in gmsh?
Note that there will be other stuff in the interior of the cube, e.g.
a cylinder, that will also need to be meshed. I know how to create a
mesh such that the cube and the cylinder which runs through it is
meshed, but I dont know how to create periodic (or similar) surface
meshes at opposite faces of the cube.
Thanks,
-Jehanzeb
