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

Hi<br class="">
<br class="">
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.<br
class="">
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.<br class="">
<br class="">
Is there a something missing in my geo or is there a way to
avoid this kind of meshing error ?<br class="">

<div class="">Recent versions (>= 2.9) should fix this. This is
what I get with the latest stable release:</div>
