[petsc-users] Accessing Global Vector Data with

[Daniel Mckinnell]

Hi,Attached is a way I came up with to access data in a global vector, is this the best way to do this or are there other ways? It would seem intuitive to use the global PetscSection and VecGetValuesSection but this doesn't seem to work on global vectors.
Instead I have used VecGetValues and VecSetValues, however I also have a problem with these when extracting more than one value, I initialise the output of VecGetValues as PetscScalar *values; and then call VecGetValues(Other stuff... , values). This seems to work some times and not others and I can't find any rhyme or reason to it?

Finally I was wondering if there is a good reference code base on Github including DMPlex that would be helpful in viewing applications of the DMPlex functions?Thanks,Daniel Mckinnell
