Dear all,
  I have one problem when I try to input the .msh file with grid_in
function. The error message is :


Exception on processing:

An error occurred in line <3139> of file
</project/cacds/build/dealii-9.2.0/source/grid/> in function
static void
std::vector<dealii::Point<dim> >&, const std::vector<dealii::CellData<3>,
std::allocator<dealii::CellData<3> > >&, const dealii::SubCellData&,
dealii::Triangulation<3, spacedim>&) [with int spacedim = 3]
The violated condition was:
Additional information:
 *   While trying to assign a boundary indicator to a line: the line with
end vertices -1 and 0 does not exist.*

I attached the gmsh .geo file in this email. There is no vertex -1
actually. Could you tell me what's wrong with my mesh generation?

Thank you very much!
