## Detailed Description

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

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.
