Hello,
thank you very much for the help, it is working fine now.
I was just having an old version because of APT... I will definitely be
more careful when installing something in the future.

Hi
I am generating a mesh from segmented pictures using contour
detection to make FEM computation on nerves. Basically I can have a
2D geometry from the segmentation, one example of my script output is
on the file 2Dtest_nerve.geo, basically when I mesh it using a simple
'gmsh -2 2Dtest....' everything is fine.
However the next step is to have a 3D structure, so in the
test_nerve.geo a new extruded nerve is biolt from the 2D previous
geometry. The resulting geometry is exactly as I expected
nevertheless I have problems when computing the 3D mesh... I have a
lot or error named 'Could not find extruded vertex'. I guess it is a
classic error, I tried to compute the distance between the nearest
point for each point and give a lc that would increase the density
but I still have these errors...the currious thing is that when I
open the mesh to see where are the missing elements, I find them all
in certain parts of the last layer from the extrusion.
Is there a something missing in my geo or is there a way to avoid
this kind of meshing error ?
Recent versions (>= 2.9) should fix this. This is what I get with the
latest stable release:
Thanks
Florian
