[petsc-users] DMPlex for high order elements

[Alejandro D Otero]

Hi, I am trying to define a spectral element mesh in the frame of DMPlex
structure.
To begin with I am thinking of quadrilateral 2d elements. Lets say I have a
16 node element with 2 nodes on each edge besides the 2 corners and 4 nodes
inside the element. I'd like to treat all nodes as vertex in the DMPlex
structure.
I am wondering whether I can make internal edge nodes (those not in the
extremes of the edge) depend on the corresponding edge and internal nodes
(those not on the element edges) depend on the corresponding element?
If this is not the right way of doing this from DMPlex philosophical point
of view, could you please give me an example?
Thanks in advance, best regards,

Alejandro
