Dear Mr.Christophe,<br>  May I ask you a question? When I use Gmsh to mesh the example of t1.geo, I found that the output file (t1.msh) did not list all line elements information, such as those lines in the interior of the rectangle. There are only information of lines elements on the edges of the rectangle in 't1.msh'. What's the matter?<br> <br>            S.Tan<br><br><br><br><br><br><table border="1" bordercolorlight="#FFFFFF" bordercolordark="#FFFFFF"width="496">  <tr>     <td width="217">      <script language="JavaScript1.1" src="http://ad263.allyes.com/main/adfshow?user=tebie|footer|footer3&db=ad263&local=yes&js=ie"></script>    </td>    <td width="263">      <script language="JavaScript1.1" src="http://ad263.allyes.com/main/adfshow?user=tebie|footer|footer4&db=ad263&local=yes&js=ie"></script>    </td>  </tr>  <tr>    <td width="217">       <script language="JavaScript1.1" src="http://ad263.allyes.com/main/adfshow?user=tebie|footer|footer1&db=ad263&local=yes&js=ie"> </!
