The coherence is by default set to 1:
Geometry.AutoCoherence = 1; // Should all duplicate entities be
automatically removed?
We usually use
Coherence;
when previously set to 0.
This command has an influence on the geometry, not on the resulting
mesh.
In your case, the geometry is ok, there are no duplicated nodes.
However, it is not the case with the mesh. You should split the
surfaces that touch for voiding duplicated nodes, nodes of the mesh.

Hi every body,
I am currently trying to mesh a
structure
made of surface elements mainly.
I'm using extrusion to generate a
structured
mesh and evrything works fine, but:
When i'm running my study, it
tells
me that my model contains many double elements (elements built
on the same
nodes actually).
I have read my file many times
but can't
figure what the probleme is ( i think about the extrusion, but
can't be
sure)
I attache my file :
Any help is welcomed !
Thanks in advance
