style="font-size: 10pt; font-family: Arial;" lang="EN-GB">I try to
mesh several very thin surfaces, structured
in a network of cracks. Two large surfaces are situated on both sides
to this network
and communicates with it. For large cracks, the mesh is correct (so I
think the
file .geo is well defined, I can send the source files if needed), but
for thinner
cracks (40e-<st1:metricconverter productid="6 m" w:st="on">6 m</st1:metricconverter>
compared to a total domain of 10e-<st1:metricconverter productid="2 m"
w:st="on">2 m</st1:metricconverter> for example), I am not able to use
a characteristic
length in the cracks smaller than their size, Gmsh sends “segmentation
fault” due to 3 identical points in qtest and crashes. The options used
for meshing surface are plane, MeshAdapt+Delaunay, a very low geometry
tolerance is used and other options are standard. I know this case is
complicated
to mesh, but would advanced options or particular strategies be able to
solve
this problem?<o:p></o:p></span></font></p>
