Detailed Description

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

Auxiliary variable which is analytically the spatial derivative of the natural log of the conformal factor.

If \(\phi\) is the conformal factor, then we define \(P_i = \partial_i ln(\phi) = \frac{\partial_i \phi}{\phi}\).
