From: Jean-Paul Pelteret Date: Wed, 14 Jun 2017 13:00:27 +0000 (+0200) Subject: Propogate settings set in TrilinosWrappers::Solver to base class. X-Git-Tag: v9.0.0-rc1~1500^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dd483d3222cc0330e891db124568092c311896f8;p=dealii.git Propogate settings set in TrilinosWrappers::Solver to base class. Also allow direct setting of AdditionalData in TrilinosWrappers::SolverBase. Fixes #4443. Supersedes #4512. --- diff --git a/doc/news/changes/minor/20170614JulianAndrejJean-PaulPelteret b/doc/news/changes/minor/20170614JulianAndrejJean-PaulPelteret new file mode 100644 index 0000000000..b71db5769b --- /dev/null +++ b/doc/news/changes/minor/20170614JulianAndrejJean-PaulPelteret @@ -0,0 +1,5 @@ +Fixed: The passing of additional settings to +TrilinosWrappers::SolverBase from derived solvers +was never completed.
