Dear Guillaume,
Dear Jean,
Thank you very much for your advice!
As Jean suggested, the surface is not closed. I turned the .msh file to
stl so that I could visualize in paraview.
I fix this by creating a script to check if every element is surrounded
by neighbour or bounding line and it works.
Thanks again and best regards,
Jarunan

Hi,
It looks like you are trying to turn an imported STL 2D shell inside
Gmsh to 3D mesh the volume inside, am I right ? If that is the case,
have a look at :
·the tutorial example 13 (id & password = gmsh) :

Objet : [Gmsh] Converting 2d to 3d mesh
Hi,
I have a problem converting a 2d mesh to 3d mesh.
I think the mesh is closed.
Does surface element orientation matter?
The error was
Info : 0 points 0 edges and 0 faces in the initial mesh
Error : No tetrahedra in region 30 0
Info : 3D point insertion terminated (0 points created):
Info : - 0 Delaunay cavities modified for star shapeness
Info : - 0 points could not be inserted
Info : - 0 tetrahedra created in 0 sec. (-2147483648 tets/sec.)
Info : Done meshing 3D (0.008999 s)
Info : 267 vertices 0 elements
Error : ------------------------------
Error : Mesh generation error summary
Error : 0 warnings
Error : 1 error
Error : Check the full log for details
Error : ------------------------------
Thank you for your help
Best regards,
Jarunan
