size=3>I would like to ask you what am I doing wrong when creating a 3D
Mesh.<SPAN style="mso-spacerun: yes"> </SPAN>I am attaching the text file
that I use for input to GMSH.<SPAN style="mso-spacerun: yes"> </SPAN>Once,
read the file by GMSH, a model can be seen consisting on three sections, with
three layers (volumes) each.<SPAN style="mso-spacerun: yes"> </SPAN>This
model is created as follows: a first section is created, located on the left
hand side, and then is replicated twice: the middle one is the first section
rotated, the right hand side one is the first section translated to the point
where it lies next to the middle one.<SPAN style="mso-spacerun: yes">
</SPAN>When meshing the whole model, the mesh generator creates a 3D mesh only
for the first section (the left hand side one), as well as for the top layer of
the other two sections.<SPAN style="mso-spacerun: yes"> However, in the
other layers of these</SPAN> sections, only a 2D mesh is generated.<SPAN
style="mso-spacerun: yes"> </SPAN>I’ve created further sections (a third
and a fourth, a fifth and a sixth, always in pairs) and setting them next to the
second and third sections (to the right of the last one), by translating the
second and third sections (not the first one); and I find that the 3D mesh is
performed ok on the newly created sections, while leaving the second and third
with a 2D mesh only. <SPAN style="mso-spacerun: yes"> </SPAN>I wonder
if there is a problem in the compatibility of the sharing faces of the
volumes.<SPAN style="mso-spacerun: yes"> Why is that so?<SPAN
style="mso-spacerun: yes"> </SPAN></SPAN>Thanks…</FONT></P>
