[Gmsh] Error of meshing result of Gmsh

[허준영]

Hi, I'm a student in Doctor's degree.
My main working subjects are geophysical modeling and inversion.

I made simple '.geo' file and tested, but the meshing results have errors
in it.
My Gmsh version is recent version(3.0.6). I added my '.geo' file and
results.
'yoon3d_0.8.mesh' is the result of the h=0.8 in '.geo' file and
'yoon3d_0.2.mesh' is the result of the h=0.2' in '.geo' file.

The first error is the overlapped or duplicated vertices.
For example, the point 84 and 120 are in same positions in 'yoon3d_0.8.mesh'
And maybe, as the result of the duplicated points, some faces are also
intersecting.

Also, if I set smaller meshes, like 'yoon3d_0.2.mesh', severe errors are
occur in 2D meshing already.
When you take a look at the outer surfaces of the 'yoon3d_0.2.mesh', you
can find some surfaces has the triangles which are overlapped badly.

Are these errors the results of the errors in my '.geo' file that I
couldn't catch?
I can't figure out what's the problem.
