Detailed Description

template<typename DataType>
struct Ccz4::Tags::LapseTimesRicciScalarPlus2DivergenceZ4Constraint< DataType >

The CCZ4 temporary expression $\alpha (R+2{\mathrm{\nabla }}_k{Z}^k)$.

Details

Here, $\alpha$ is the lapse defined by gr::Tags::Lapse and $(R+2{\mathrm{\nabla }}_k{Z}^k)$ is the Ricci scalar plus twice the divergence of the spatial Z4 constraint defined by Ccz4::Tags::RicciScalarPlusDivergenceZ4Constraint.
