Detailed Description

template<typename DataType, size_t Dim, typename Frame>
struct Ccz4::Tags::FieldDUpTimesATilde< DataType, Dim, Frame >

The CCZ4 temporary expression \(D_k{}^{nm} \tilde{A}_{nm}\).

Details

Here, \(D_k{}^{nm}\) is analytically negative one half the spatial derivative of the inverse conformal spatial metric defined by Ccz4::Tags::FieldDUp and \(\tilde{A}_{nm}\) is the trace-free part of the extrinsic curvature defined by Ccz4::Tags::ATilde.
