## Detailed Description

### template<size_t Dim> struct NewtonianEuler::ConservativeFromPrimitive< Dim >

Compute the conservative variables from the primitive variables.

\begin{align*} S^i &= \rho v^i \\ e &= \dfrac{1}{2}\rho v^2 + \rho\epsilon \end{align*}

where $S^i$ is the momentum density, $e$ is the energy density, $\rho$ is the mass density, $v^i$ is the velocity, $v^2$ is its magnitude squared, and $\epsilon$ is the specific internal energy. In addition, this method returns the mass density as a conservative.
