[petsc-users] Inquiry about reading the P2 tetrahedron mesh from GMSH

[neil liu]

Dear Petsc developers,

I am reading P2 mesh from GMSH. And used DMFieldGetClosure_Internal to
check the coordinates for each tetrahedron, It seems reasonable.
But when I tried DMGetCoordinates (dm, &global),  it seems the vector
global is not consistent with the node number, Then what is global here?

Thanks,

Xiaodong
