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. |
