Dear Jed,
Thank you for the suggestion. When I run tests/ex33.c with ./ex33 -dm_plex_simplex 0 -dm_plex_box_faces 1,1 -mesh_transform annulus -dm_coord_space 0 -dm_coord_petscspace_degree 3 -dm_refine 1 -dm_view cgns:test.cgns and load it using Paraview, the mesh is still with straight lines. Should I modify the code to make cgns work? Or any other examples for me to start? Thanks!

VTU is not a great format for this. It wants > everything at first order. I would recommend configuring with --download-cgns and running with -dm_view cgns:output.cgns. This format has efficient parallel IO and curved elements work for moderate order in Paraview.
