[petsc-users] How to get Gmsh boundary edge/face tags

[Praveen C]

Dear all

In a 2d mesh I save some tags like this

Physical Line(100) = {1,2};
Physical Line(200) = {3,4};

so that I can identify boundary portions on which bc is to be applied.

How can I access this tag (100,200 in above example) after reading the msh file into a DMPlex ?

Thanks
