<font face="Times New Roman, Times, serif"> 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>
