Detailed Description

template<typename DataType, size_t Dim, typename Frame>
struct gh::Tags::Phi< DataType, Dim, Frame >

Auxiliary variable which is analytically the spatial derivative of the spacetime metric.

If \(g_{ab}\) is the spacetime metric then we define \(\Phi_{iab} = \partial_i g_{ab}\)
