Hi, Mikhail!<br><br>Yes, I can read Russian and I have found the problem! Thank you, Mikhail! The problem was that the example file from wiki did not have volume definition part. I have added following lines:<br><br>Surface Loop(1) = { 5, 8, 11, 14, 17, 20, 23, 26 };<br>
Volume(1) = { 1 };<br><br>and 3D FEM mesh was successfully created.<br><br>Sincerely,<br>Alexander<br><br><div class="gmail_quote">On Sun, Jun 3, 2012 at 5:14 PM, Mikhail Artemiev <span dir="ltr"><<a href="mailto:artemiev.mikhail@ngs.ru" target="_blank">artemiev.mikhail@ngs.ru</a>></span> wrote:<br>

If you can read Russian, you can look at <a href="http://numlab.blogspot.com/2011/06/gmsh-3d.html" target="_blank">http://numlab.blogspot.com/<u></u>2011/06/gmsh-3d.html</a> for detailed step-by-step instructions on how to build 3D mesh in Gmsh (sphere-in-cube geometry is considered, so it's almost your case!).<br>
