Detailed Description

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

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

If $α$ is the lapse, then we define $A_{i} = \partial_{i} l n (α) = \frac{\partial_{i} α}{α}$ .
