## Detailed Description

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

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

### Details

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