From 72b38710fa90f3efbf860ad4693c0cdc8985cafd Mon Sep 17 00:00:00 2001 From: schnetter Date: Wed, 1 Mar 2006 02:19:46 +0000 Subject: Introduce a parameter TP_epsilon that can be used to smooth out initial data. It has the same meaning as for the Brill-Lindquist initial data in thorn AEIThorns/Exact, namely by r -> (r^4 + epsilon^4)^(1/4) By default, epsilon=0, which introduces no change. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/TwoPunctures/trunk@51 b2a53a04-0f4f-0410-87ed-f9f25ced00cf --- param.ccl | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'param.ccl') diff --git a/param.ccl b/param.ccl index 8764a16..d578502 100644 --- a/param.ccl +++ b/param.ccl @@ -71,6 +71,11 @@ INT Newton_maxit "Maximum number of Newton iterations" 0:* :: "" } 5 +REAL TP_epsilon "A small number to smooth out singularities at the puncture locations" +{ + 0:* :: "" +} 0.0 + REAL TP_Tiny "Tiny number to avoid nans near or at the pucture locations" { 0:* :: "anything positive, usually very small" -- cgit v1.2.3
