Detailed Description

template<size_t Dim>
class NewtonianEuler::Sources::UniformAcceleration< Dim >

Source generated from an external uniform acceleration.

The NewtonianEuler system with source terms is written as

\begin{align*} \partial_t\rho + \partial_i F^i(\rho) &= S(\rho)\\ \partial_t S^i + \partial_j F^{j}(S^i) &= S(S^i)\\ \partial_t e + \partial_i F^i(e) &= S(e), \end{align*}

where \(F^i(u)\) is the volume flux of the conserved quantity \(u\) (see ComputeFluxes). For an external acceleration \(a^i\), one has

\begin{align*} S(\rho) &= 0\\ S(S^i) &= \rho a^i\\ S(e) &= S_ia^i, \end{align*}

where \(\rho\) is the mass density, \(S^i\) is the momentum density, and \(e\) is the energy density.
