I have a very simple PyGmsh script to produce, for example, a triangulation
of the disk (attached)
I'd like to use this in "Introduduction: Example 3" (solving 2D poisson)
by replacing
MeshTools::Generation::build_square (mesh,
n_elements_1dim, n_elements_1dim,
xmin_mesh, xmax_mesh,
ymin_mesh, ymax_mesh,
QUAD9);
with
GmshIO gmsh_io(mesh);
gmsh_io.read("disk.vtu");
but--and I am not sure if this is possible--imposing additional nodes on
each element generated in the triangularization generated by gmsh with
nodes such that I have, say, Tri6 elements.
Is this possible through libmesh, or something I would I have to do
something in gmsh instead?
Thanks for reading, and Happy Thanksgiving
