Detailed Description

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

The CCZ4 temporary expression \(\tau^{-1} \tilde{\gamma}_{ij}\).

Details

Here, \(\tilde{\gamma}_{ij}\) is the conformal spatial metric defined by Ccz4::Tags::ConformalMetric and \(\tau\) is the relaxation time to enforce the algebraic constraints on the determinant of the conformal spatial metric and on the trace of the trace-free part of the extrinsic curvature that is defined by Ccz4::Tags::ATilde.
