From af65d25da36a14474c105737443dcd5084532435 Mon Sep 17 00:00:00 2001 From: Timo Heister Date: Wed, 14 Feb 2018 15:50:34 -0500 Subject: [PATCH] fix step-3 convergence of mean numbers It looks like the numbers were incorrect (same value for refinement 3&4). Fix this and give output with more digits. --- examples/step-3/doc/results.dox | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/examples/step-3/doc/results.dox b/examples/step-3/doc/results.dox index e2054cee20..a39a00addc 100644 --- a/examples/step-3/doc/results.dox +++ b/examples/step-3/doc/results.dox @@ -203,15 +203,15 @@ suggestions: the following result: - - - - - - - - - + + + + + + + + +

Again, the difference between two adjacent values goes down by about a factor of four, indicating convergence as ${\cal O}(h^2)$. -- 2.39.5
