<div class="moz-cite-prefix">Hi,<br>
I think I got it now. The numbers after dimension for the line
entity inside Periodic are the matching tag entities for the
lines. I was getting confused as I kept looking at line labels.<br>
<br>
Thanks again<br>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span
lang="EN-US"> </span>Hi there,<br>
I am meshing a geometry with periodic (translated meshes)
boundary conditions along one of the directions (X in my
case). I am using<br>
periodic surface with translate to setup the translated
periodic meshes. I need help understanding some entries in the
Msh file generated specifically the section under "$Periodic"
(See attached image, in my case surfaces 1 and 8 are
periodic). I understand that in my case their are totally 11
periodic entities -- 5 points , 5 lines and 1 surface and my
trouble is in understanding the format of the output
corresponding to each of these periodic entities. It will be
of great help if some one explain to me what is the format for
each of these entities so that I can write a code to read the
msh file and generate relevant input files for my finite
element solver. I have attached the geo and mesh file.<br>
<br>
Thanks again<br>
