Detailed Description

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

The CCZ4 temporary expression \(\tilde{A}_{ij} - \frac{1}{3} \tilde{\gamma}_{ij} tr \tilde{A}\).

Details

Here, \(\tilde{A}_{ij}\) is the trace-free part of the extrinsic curvature defined by Ccz4::Tags::ATilde, \(tr \tilde{A}\) is its trace defined by Ccz4::Tags::TraceATilde, and \(\tilde{\gamma}_{ij}\) is the conformal spatial metric defined by Ccz4::Tags::ConformalMetric.
