Hallo,
I am using Gmsh 2.3.0
when I mesh the attached .geo file with gmsh expCi.geo -2 -rand 1E-8
I get this information on the std output:

So no errors. But I when I open the .msh file with gmsh I cannot see anything.
When I open the .msh file with an text editor it says:
$MeshFormat
2 0 8
$EndMeshFormat
$Nodes
3460
in the first few lines, which seems to be a contradiction to the info from std
output. Also the msh files's size is less then 1 MB which seems to be to small
for the large number of elements
What to do to geht this .geo file meshed?
kind regrads and thanks in advance
