From 2d031812d302379fe809b35d4c834451b0dde2cb Mon Sep 17 00:00:00 2001 From: goodale Date: Thu, 25 Apr 2002 22:03:52 +0000 Subject: Initial import of new Einstein stuff. This has the new thorns, but not all are fully functional yet. When I have completed this stage I'll send an updated spec out with some questions which have arisen during this process. Please don't import anything new without checking with me first, as I want to play games on the server copying cvs files around to preserve histories on files which are only minimally touched.

If this thorn is +active and the ADMBase::metric_type parameter is set to +`static conformal' then the ADMBase::g... variables are the +conformal values as opposed to the physical values. + +The transformation is + +$$ g_{ij}^{\mbox{physical}} = \psi^4 g_{ij}^{\mbox{conformal}} $$ + +The extrinsic curvature is not transformed. -- cgit v1.2.3
