Dear list members,<br>
<br>
I'm trying to produce a 3D mesh consisting two regions: a region
with unstructured tetrahedral mesh and an attached region with
structured hexahedral mesh. Obviously, the unstrucutred part needs
to include some pyramid elements to facilitate the connection. By
using google I realized that the stable release doesn't support
this, but according to <span class="_username"><span style="color:

for an earlier question
(<a class="moz-txt-link-freetext" href="https://groups.google.com/forum/?fromgroups#!topic/gmsh-public/mUYykAaFGp4">https://groups.google.com/forum/?fromgroups#!topic/gmsh-public/mUYykAaFGp4</a>)
that the svn version contains an experimental support for this.
However, using this, I receive the following error message for
every face elements interconnecting the two domains:<br>
<br>
Error : Cannot build pyramids on non manifold faces<br>
<br>
In order to trace up the problem, I decided to build an
extremely simplified model containing two boxes (attached file),
but this yields the same error messages and I can not find the
error in the geometry.<br>
<br>
What am I doing wrong?<br>
<br>
Thank you for your help in advance,<br>
<br>
