One solution would be to implement side number method in iMesh;<br>Or to look at connectivity array and figure out from there the order. I am not sure which one would be easier to do or be more efficient. <br><br>Iulian<br><blockquote style="border-left:2px solid #1010FF;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><br>For example, consider a mesh of quadrilaterals. Get the edges adjacent<br>to a given face. If the edges are numbered according the convention<br>defined by MOAB<br>(http://www.mcs.anl.gov/uploads/cels/papers/P1573A.pdf) I would get<br>the array (0,1,2,3) or some shifted version of this. Will<br>iMesh_getEntAdj return (0,1,2,3) (or a shifted/flipped version of it),<br>or could I get something like (1,3,2,0) back (where the edges are not<br>ordered with respect to a CW or CCW traverse around the face)?<br><br>Thanks,<br>-Chris Eldred<br><br><br>-- <br>Chris Eldred<br>DOE Computational Science Graduate Fellow<br>Graduate Student, Atmospheric Science, Colorado State University<br>B.S.
