[petsc-users] DMPlex examples in parallel/3D?

[Mark Lohry]

Great thanks, I'll look more into this.

Question on the dofs that wasn't clear from the manual - are the dofs on 
cells, faces, edges, and vertices *all* actual degrees of freedom / 
solution unknowns in the system to solve, or does one say the dofs on 
the cells represent actual solution unknowns, and face dofs are just 
things to be communicated for inter-cell flux computation? e.g. say i 
was doing the simplest cellwise-constant finite volume scheme for a 
scalar; do i have 1 dof per cell, and zero dofs anywhere else?

perfect, i'll start with that.

Great thanks, didn't see these linked from the DMPlex doc pages.
