Export periodic boundaries in CGNS
Hi, I am using your software through the python API to generate CGNS periodic meshes. The CGNS file generated has periodic nodes for points lines and surfaces, but the location of lines and surfaces is Vertex. CGNS norm allows to define periodic conditions as well on surfacic elements (https://cgns.github.io/CGNS_docs_current/sids/cnct.html, §8.4, Note 4).
Here an exemple : periodic_cube_raw.cgns
In this file, I think that Per_0-S*
nodes could have a GridLocation node set to FaceCenter
to tag through PointList
and PointListDonor
which faces are connected by the periodic condition (instead of Vertex now).
Do you think that is it possible to manage this case ?
I think that both informations (Vertex of FaceCenter) are interesting depending on application.
