Detailed Description

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

The CCZ4 temporary expression \(\beta^k \partial_k \hat{\Gamma}^i\).

Details

Here, \(\beta^k\) is the shift defined by gr::Tags::Shift, \(\hat{\Gamma}^i\) is the CCZ4 evolved variable defined by Ccz4::Tags::GammaHat, and \(\partial_k \hat{\Gamma}^i\) is its spatial derivative.
