Detailed Description

template<typename DataType>
struct Ccz4::Tags::KMinus2ThetaC< DataType >

The CCZ4 temporary expression \(K - 2 \Theta c\).


Here, \(K\) is the trace of the extrinsic curvature defined by gr::Tags::TraceExtrinsicCurvature, \(\Theta\) is the projection of the Z4 four-vector along the normal direction, and \(c\) controls whether to include algebraic source terms proportional to \(\Theta\).
