about Unstructured Meshes

[Jianing Shi]

Actually, I have a very similar question for unstructured meshes.

I took a look at the tutorial in PETSc using meshes.  Looks like there
is a mixture programming of meshes (written in OOP) and the PETSc
solver.  Looks very complicated, I must say.

Besides, what would be a golden packages using meshes that would work
with PETSc?  Say, PETSc (solver) +  ParMetis (partition meshes) + Some
sort of mesh generators (I don't what)?
