Matt,

The code is actually for 2d.

Stefano is right that you will need a mesh generator for a simplex mesh.
However, you are asking for
a 1D mesh for which there are no generators. Since in 1D simplces and
tensor cells are the same,
just change it to tensor and it will work.

  Thanks,

 Matt

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.

You need a grid generator like triangle or tetgen. Reconfigure petsc adding
-- download-triangle --download-ctetgen

I would guess that you want 2 faces in each direction (the default so use
NULL instead of faces).
