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

Identity which is analytically negative one half the spatial derivative of the inverse conformal spatial metric.

Details

We define:

$\begin{aligned} (1) & D_{k}^{i j} & = {\tilde{γ}}^{i n} {\tilde{γ}}^{m j} D_{k n m} = - \frac{1}{2} \partial_{k} {\tilde{γ}}^{i j} \end{aligned}$

where ${\tilde{γ}}^{i j}$ and $D_{i j k}$ are the inverse conformal spatial metric and the CCZ4 auxiliary variable defined by Ccz4::Tags::FieldD, respectively.
