Detailed Description

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

The CCZ4 temporary expression \(\alpha (R + 2 \nabla_k Z^k)\).

Details

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