hydro::Tags::SpatialVelocity< DataType, Dim, Fr > Struct Template Reference

The spatial velocity \(v^i\) of the fluid, where \(v^i=u^i/W + \beta^i/\alpha\). Here \(u^i\) is the spatial part of the 4-velocity of the fluid, \(W\) is the Lorentz factor, \(\beta^i\) is the shift vector, and \(\alpha\) is the lapse function. Note that \(v^i\) is raised and lowered with the spatial metric. More...
