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. |
