With an old version of gmsh (2.0.8), this geo file works fine, it generates the mesh,<br> so it is great. But with this old version, I don't have fourth order available for tetrahedral elements :(<br>With the new version (2.4.2), it gives the following output error :<br><br>Error : No tetrahedra in region 1 0<br><br>Do you have an idea about that problem ?<br><br><br></div><!-- cg22.c41.mail.ird.yahoo.com compressed/chunked Sun Dec 20 03:45:06 PST 2009 -->
