From 82e885a5f981717bf4645652990b76019b8a8a24 Mon Sep 17 00:00:00 2001 From: kronbichler Date: Wed, 24 Sep 2008 07:11:30 +0000 Subject: [PATCH] Reduced residual tolerance for CG solve in inverse matrix by a factor of 10. It is essential to solve the inner matrix to high enough accuracy, since inaccuracies significantly increase the number of outer GMRES iterations. git-svn-id: https://svn.dealii.org/trunk@16907 0785d39b-7218-0410-832d-ea1e28bc413d --- deal.II/examples/step-32/step-32.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/deal.II/examples/step-32/step-32.cc b/deal.II/examples/step-32/step-32.cc index 99acd25813..853aecf245 100644 --- a/deal.II/examples/step-32/step-32.cc +++ b/deal.II/examples/step-32/step-32.cc @@ -192,7 +192,7 @@ namespace LinearSolvers TrilinosWrappers::MPI::Vector &dst, const TrilinosWrappers::MPI::Vector &src) const { - SolverControl solver_control (src.size(), 1e-6*src.l2_norm()); + SolverControl solver_control (src.size(), 1e-7*src.l2_norm()); SolverCG cg (solver_control); dst = 0; -- 2.39.5
