The CCZ4 temporary expression \(D_k{}^{nm} \tilde{A}_{nm}\).
Here, \(D_k{}^{nm}\) is analytically negative one half the spatial derivative of the inverse conformal spatial metric defined by Ccz4::Tags::FieldDUp
and \(\tilde{A}_{nm}\) is the tracefree part of the extrinsic curvature defined by Ccz4::Tags::ATilde
