From: wolf Date: Mon, 19 Nov 2001 14:50:34 +0000 (+0000) Subject: Revert the order of checks for a) max. number of iterations, and b) X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ae72e253a9d72e219682acf09c6ffad80faabc1;p=dealii-svn.git Revert the order of checks for a) max. number of iterations, and b) target residual. The reason is that it happens that we converge on the very last allowed iteration, most often if the system has only 5 or so equations, and we converge in the fifth iteration. git-svn-id: https://svn.dealii.org/trunk@5214 0785d39b-7218-0410-832d-ea1e28bc413d --- diff --git a/deal.II/doc/news/2001/3.2.0-vs-3.2.1.html b/deal.II/doc/news/2001/3.2.0-vs-3.2.1.html index 5d34729ea6..ab0d96bb77 100644 --- a/deal.II/doc/news/2001/3.2.0-vs-3.2.1.html +++ b/deal.II/doc/news/2001/3.2.0-vs-3.2.1.html @@ -14,6 +14,18 @@

Changes between versions 3.2.0 and 3.2.1

    +
  1. + Fixed: when checking for convergence in linear solvers in + SolverControl::check, we first + checked whether the maximal iteration count was reached, and + only then whether the target residual was achieved. In cases, + where the target residual was only reached in the very last + allowed iteration, this led to a failure notice of the linear + solver, rather than to a success message. This is now fixed. +
