Adding Python Example for PETSc Bake-Off Problem

[tylercollins5737]

Hello libCEED Team,

I noticed an open issue #1763 and I'm also interested in adding to the library of python examples, specifically starting with the first PETSc bake-off problem. It was mentioned that some advanced methods might not be available but could be added. Should I just go for it and report any missing or needed methods?

Appreciate your time and any suggestions!

Cheers,
Tyler

Yup, go ahead and get started. You'll probably use petsc4py for generating the mesh and handling the solver, with libceed for applying the operator. You may need to look at the petsc4py examples at least as much as libceed examples to see how to implement things like matrix-free operators (which will call ceed.Operator.apply).

Let us know if you get stuck. It's usually best to create a draft PR with your work along the way so you have a place to ask questions where we'll see it in context.

I thought #1763 was about that particular person offering to make more Python examples? Worth clarifying in that issue

Sounds good and thank you for the tips!

That was a good point, and I got clarification so we aren't overlapping in our efforts.
