Hi!<br><br>I'm relatively new to this world so go soft on me. <br><br>I am using Gmsh as a mesh generator for a 2D CFD code on my master thesis, but the thing is that i have to be able to explain every step taken by Gmsh when it computes an unstructured mesh. I can't understand the inicial step described in the manual :<br>
<br>"For all 2D unstructured algorithms a Delaunay mesh that contains all the points of the<br>1D mesh is initially constructed using a divide-and-conquer algorithm. Missing edges are<br>recovered using edge swaps. After this initial step three different algorithms can be applied<br>
to generate the final mesh..."<br><br>What 1D mesh? How are there missing edges?<br><br>The second questions comes regarding the point generation algorithm. I can't find any reference to any, like grid superposition, boudary point distribution...<br>
<br>Any help is more than welcome!<br><br>Best regards, <br><br clear="all"><br>-- <br>Ricardo Canelas<br><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CDOCUME%7E1%5CVANESS%7E1%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CDOCUME%7E1%5CVANESS%7E1%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CDOCUME%7E1%5CVANESS%7E1%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>
