Dear Matt,


Thank you for the reply. I have a more specific question about the spectral element example. Do you have any suggestions that how to write all the nodes in each cell to .vtu?


Thanks!

Dear all,


I am playing with dm/impls/plex/tests/ex33.c and know how to set high-order geometry.

Is it possible to output the final mesh to vtu, e.g. annulus example?


The problem is that VTK has no nice, standard way to talk about higher order polynomials. Thus, the
best way to do this is to call DMRefine() once or twice and output that mesh.

Thanks!
