<DIV><FONT face=Arial color=#000000 size=2>I have found a bug in meshing information.<BR>I found the tetrahedra element counter was wrong.<BR>There are actully 102 tetrahedra elements generted while the statistics given in meshing process gave us 101 (see below).<BR>I call gmsh program in Matlab and use the element and node information for analysis. <BR>I found that the meshing information given by gmsh in counting. See the attached file test1.msh. There are 102 tetrahedra elements generated subtantiilly from 117 to 218.</FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2>218-117+1 = 102. But the statistics informatio gave us 101.<BR>The .gmsh and .geo file is attached in this mail.</FONT></DIV><FONT color=#000000 size=2>
