<div dir="ltr"><div class="gmail_extra">Hi,<br><br></div><div class="gmail_extra">With gmsh 2.9.3 on Ubuntu 64-bit, I got exactly 10 triangles per side as expected. My guess is that you have a global setting in ~/.gmshrc or ~/.gmsh-options that affects the characteristic length size. Save those files somewhere, and do Tools->Options->General->Advanced->Restore all options to default settings. Then check if it helps. If not, just copy setting files back.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Best,<br></div><div class="gmail_extra">Mikhail<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jun 30, 2015 at 5:00 AM, <span dir="ltr"><<a href="mailto:gmsh-request@ace20.montefiore.ulg.ac.be" target="_blank">gmsh-request@ace20.montefiore.ulg.ac.be</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div id=":127" class="a3s" style="overflow:hidden">Hi there,<br>
<br>
I found the characteristic length is rather intriguing.<br>
<br>
I used the following code<br>
<br>
Point(1) = {0, 0, 0, 0.1};<br>
Extrude {1, 0, 0} {<br>
Point{1};<br>
}<br>
Extrude {0, 1, 0} {<br>
Line{1};<br>
}<br>
<br>
and GMSH gives three elements per side. See attachment. Should I expect 10<br>
elements? or I misunderstood the definition?<br>
<br>
Thanks in advance.<br>
