From 5060c634715cbaa4765da67d17defb4eb284f56f Mon Sep 17 00:00:00 2001 From: Wolfgang Bangerth Date: Tue, 2 Mar 2004 20:22:36 +0000 Subject: [PATCH] Improved: When eliminating nodes from a matrix using the ConstraintMatrix::condense functions, the diagonal entry was set to one. It is now set to an entry that more resembles the size of the other diagonal entries, so that we don't run into scaling problems for applications that have very large or small domains. git-svn-id: https://svn.dealii.org/trunk@8636 0785d39b-7218-0410-832d-ea1e28bc413d --- deal.II/doc/news/c-4-0.html | 32 +++++++++++++++++++++----------- 1 file changed, 21 insertions(+), 11 deletions(-) diff --git a/deal.II/doc/news/c-4-0.html b/deal.II/doc/news/c-4-0.html index 6434edf7a2..1ab9ec8ee1 100644 --- a/deal.II/doc/news/c-4-0.html +++ b/deal.II/doc/news/c-4-0.html @@ -287,21 +287,31 @@ contributor's names are abbreviated by WB (Wolfgang Bangerth), GK
