[petsc-users] Get DM used to create Vec

[Carl-Johan Thore]

Hi,

Given a Vec (or Mat) created at some point with DMCreate...,
is it possible to retrieve from this Vec a pointer to the DM used
to create it?

(I could perhaps build my own Vec-type on top of PETSc's
which carried with it such a pointer but that doesn't seem like
a good idea)

Kind regards,
Carl-Johan
