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.
