<br>The real numeric values may be defined in a small file named, say: par.inc.<br>This file may be easily generated by a shell script or by some other program such as octave.
<br>then you include this file in the beginning of the .geo file.<br>You can also control gmsh and the solver with a shell script or octave, automating the whole process in a loop, by changing the parameters at each iteration.
<br><br>par.inc:<br>a = 0.01;<br>b = 0.02;<br>cl = 1;<br><br>.geo:<br>Include "par.inc";<br>Point( 1) = {a, b, 0, cl};<br>... etc...<br><br>I've done a lot of automation with this scheme. The computer plays all the night, while I sleep.
<br>BTW which solver are you using?<br><br>Regards<br>Janvrot<br><br><br><div><div><span class="e" id="q_1144826f4e1bf5c3_1"><span class="gmail_quote">On 8/8/07, <b class="gmail_sendername">Cynthia Maxwell</b> <<a href="mailto:cynthia.maxwell@mac.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
