From 4c7144d8e695475f86fec845e0730179a8959fc2 Mon Sep 17 00:00:00 2001 From: diener Date: Thu, 15 Dec 2005 03:54:19 +0000 Subject: Introduce a new kind of dissipation operators. Kreiss-Oliger type dissipation operator suitably modified near the boundary. Since the dissipation operator in the interior uses a stencil that is one point wider than the derivative operator, an additional check on the number of ghostzones in multi processor runs have been added. Only implemented for the 8-4 and optimized 6-5 operators. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/SummationByParts/trunk@53 f69c4107-0314-4c4f-9ad4-17e986b73f4a --- param.ccl | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'param.ccl') diff --git a/param.ccl b/param.ccl index 4e3fda5..ff72a06 100644 --- a/param.ccl +++ b/param.ccl @@ -27,6 +27,12 @@ BOOLEAN scale_with_h "Should we scale the dissipation with the grid spacing h" { } "no" +KEYWORD dissipation_type "Type of dissipation operator" STEERABLE=always +{ + "Mattson-Svard-Nordstrom" :: "Mattson, Svaerd and Nordstroem type" + "Kreiss-Oliger" :: "Kreiss-Oliger modified near the boundaries" +} "Mattson-Svard-Nordstrom" + REAL epsdis "Dissipation strength" STEERABLE=always { *:* :: "Values typical between 0 and 1" -- cgit v1.2.3
