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 \( \alpha \) is the lapse, then we define \(A_i = \partial_i ln(\alpha) = \frac{\partial_i \alpha}{\alpha}\).
