That is all true. If you want lower level pieces to make it yourself, I have
-dm_plex_high_order_view, which activates
DMPlexCreateHighOrderSurrogate_Internal(). This is a simple function that
refines the mesh lg(p) times to try and
resolve

I like the CGNS workflow for this, at least with quadratic and cubic elements.
You can use options like -snes_view_solution cgns:solution.cgns (configure with
--download-cgns). It can also monitor transient solves with flexible batch
sizes (geometry and connectivity are stored only once within a
Hello,
We have created a finite element code in PETSc for unstructured meshes using
DMPlex. The first order meshes are created in gmsh and loaded into PETSc. To
introduce higher order elements, e.g. 10 node tetrahedral elements, we start
from scratch using PetscSection and loop over the relevan
