Dear All,
I am trying to use gmsh's API. I can successfully use it to setup my
geometry and generate the mesh. The only issue I am having is that I cannot
find the function (both in Python and C++) to define Periodic Lines (or
Periodic Surfaces). Does anyone know this?
Thank you.

Dear Artur, what you can do is something along these lines:
// constrain the boundary surfaces to conformal discretization
// x
Periodic Surface {2} = {1} Translate {400,0,0}; // ex
// y
Periodic Surface {4} = {3} Translate {0,300,0}; // ey
// z - floor and roof
Periodic Surface {
Dear Benedikt,
Thank you for your reply. Unfortunately I am unable to understand exactly
what you mean by that. Roughly I think that you define the periodic surface
2 (for example) to be the translation along [400,0,0] of the surface 1.
Still you make use of the Periodic Surface call. My problem i
Hi Arthur,
Indeed it's currently missing from the API - we'll add it soon.

Hi Artur - it's now in the API: give it a try.
PS: we have started to generate binary SDKs that contain the shared Gmsh
library and the C++/C headers and Python module (see the *-sdk* files in
gmsh.info/bin/). The SDK is built using the same compilers as the official
builds, with the same opti
Christophe,
It works like a charm! Thank you very much for the extremely quick
addition. One thing, I need to add a gmsh.model.geo.synchronize() begore
the periodic line right? Otherwise the entities are not available (just to
be sure I am not missing anything).
Once again thank you!
P.S.: I tri
Dear Christophe,
I have one more question. After adding the periodic lines how can I have
access to the periodicity information (master/slave) for the nodes of the
mesh? Similar to what is found between $Periodic and $EndPeriodic in the
msh file.
Once again thank you.

Dear Christophe,
I think I found out how to get that information. If I get the nodes
associated to the master and slave line entities I get the master and slave
nodes. They are given in the same order (up to a order reversal given by
the Affine transformation).
