Subject: PETScWrappers: don't call deprecated viewer functions.
X-Git-Tag: v9.6.0-rc2~5^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F17429%2Fhead;p=dealii.git

PETScWrappers: don't call deprecated viewer functions.

This was deprecated in PETSc 3.7 - since we require at least that version we can
use the new function.
