Hello!<br><br>I am new to gmsh and I am trying to build very simple 3D FEM mesh for the sphere. I have downloaded latest version of gmsh (2.5.0), next I downloaded sphere geometry from the wiki: <a href="https://geuz.org/trac/gmsh/attachment/wiki/OldExamples/sphere.geo">https://geuz.org/trac/gmsh/attachment/wiki/OldExamples/sphere.geo</a>, loaded geometry and just click on the Mesh/3D button.<br>
<br>The 2D mesh was created successfully. But I cannot see 3D mesh. The Tools/Statistics shows that there no tetrahedra was created.<br><br>Could you please help me, what is the problem and how to create 3D FEM mesh for the sphere?<br>
<br>Thank you,<br>Alexander.<br>
