Hi,
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.
Thanks again

Hi,
Have you looked at the documentation here
<http://gmsh.info/doc/texinfo/gmsh.html#MSH-ASCII-file-format> ? It says :
/$Periodic/
/number-of-periodic-entities/
/dimension slave-entity-tag master-entity-tag/
/number-of-nodes/
/slave-node-number master-node-number/
/…/
/$EndPeriodic/
It looks like your information.
Faithfully Yours,

*Objet :* [Gmsh] Help understanding MSH file entries while using
"Periodic surface with translate "
Hi there,
I am meshing a geometry with periodic (translated meshes) boundary
conditions along one of the directions (X in my case). I am using
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.
Thanks again
Ranga Sudarsan
