Detailed Description

template<typename DataType, size_t Dim, typename Fr = Frame::Inertial>
struct hydro::Tags::QuadrupoleMoment< DataType, Dim, Fr >

Tag containing the quadrupole moment.

The quadrupole moment is defined as $\tilde{D}{x}^i{x}^j$ (equation 21 of [178]), with $\tilde{D}=\sqrt{\gamma }\rho W$, $W$ being the Lorentz factor, $\gamma$ being the determinant of the spatial metric, and $x$ the coordinates in Frame Fr.
