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...

### template<typename DataType, size_t Dim, typename Fr> struct hydro::Tags::SpatialVelocity< DataType, Dim, Fr >

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.
