<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear Henk,<br><br>Thanks for the reply-it answers part of my question, that is, how to mesh the volume between the outer cuboid and the inner STL model.<br><br>However, how do I generate a mesh which is fine around the inner surface (the model) and becoming coarse towards the surrounding cuboid?. I tried using the threshold and attractor fields but it seems the latter does not support surfaces:<br>http://geuz.org/pipermail/gmsh/2009/004198.html<br><br>Is it possible to extract the surface points of the model and use them as attractors?.<br><br>Thanks,<br>MIke.<br><cite></cite><br><br>--- On <b>Thu, 6/18/09, dolfyn <i><info@dolfyn.net></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: dolfyn <info@dolfyn.net><br>Subject: Re: [Gmsh] Meshing the volume between a model and a
