Detailed Description

template<typename DataType>
struct Ccz4::Tags::KMinusK0Minus2ThetaC< DataType >

The CCZ4 temporary expression $K-K_0-2\mathrm{\Theta }c$.

Details

Here, $K$ is the trace of the extrinsic curvature defined by gr::Tags::TraceExtrinsicCurvature, $K_0$ is the initial time derivative of the lapse, $\mathrm{\Theta }$ is the projection of the Z4 four-vector along the normal direction, and $c$ controls whether to include algebraic source terms proportional to $\mathrm{\Theta }$.
