<b>Betreff:</b> [Gmsh] [Question] I need help to make tetrahedral mesh with STEP file<br>
</font><br>

<p><font size="3" face="times">Dear developers and colleagues,</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">I am trying to make tetrahedral elements by Gmsh with CAD file (*.step).</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">In a CAD design, I used two cylinders just like water in a cup. (part1 is cup and part2 is water).</font></p>
<p><font size="3" face="times">In this geometry, two faces are in contact with each other. (bottom of water and side of water).</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">Is it possible to make tetrahedral mesh that two faces share same nodes on the contacting surface?</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">With the current version of Gmsh (2.5.1), it seems that each volume has their own nodes on the contacting surface not sharing each others.</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">In the reactor physics calculation, we need this option very much.</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">Please consider above problems.</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">If the current version of Gmsh (2.5.1) has a option for this, please let me know.</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">I am attacing step file (Product1.stp) for above geometry.</font></p>
<p><font size="3" face="times"></font> </p>
<p><font size="3" face="times">I really appreciate it in advance.</font></p>
