Detailed Description

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

The CCZ4 temporary expression \(\alpha \partial_k \tilde{A}_{ij}\).

Details

Here, \(\alpha\) is the lapse defined by gr::Tags::Lapse and \(\tilde{A}_{ij}\) is the trace-free part of the extrinsic curvature defined by Ccz4::Tags::ATilde, and \(\partial_k \tilde{A}_{ij}\) is its spatial derivative.
