[petsc-users] DMplex periodicity type

[Matteo Semplice]

Dear all,

     regarding the two possible ways to represent periodic meshes in 
DMPlex (https://urldefense.us/v3/__https://petsc.org/release/manual/dmplex/*__;Iw!!G_uCfscf7eWS!aZty3mcKlmFws6oDH6dzJajWmHL38hq4105g81qWT-9vNW5RcQ7t39SXetxoJEpVVF_VJno1viNSyiomGVPsLrvdvU75tWZbkMCJaQ$ ), I have noticed that 
when reading in a GMSH mesh, the periodic topology is created.

Is there a way to read in a mesh and create instead the non-periodic 
topology&local-to-global-map kind of mesh? Or, is it possible to convert 
between the two approaces (i.e. generate a DMPlex that is a quasi-clone 
of a given one, but ready for the other kind of periodicity handling)?

Bets regards

     Matteo
