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 $ϕ$ is the conformal factor, then we define $P_{i} = \partial_{i} l n (ϕ) = \frac{\partial_{i} ϕ}{ϕ}$ .
