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

$$\begin{array}{rl}{\partial }_t\rho +{\partial }_i{F}^i(\rho )& =S(\rho )\\ {\partial }_t{S}^i+{\partial }_j{F}^j(S^i)& =S(S^i)\\ {\partial }_{t}e+{\partial }_i{F}^i(e)& =S(e),\end{array}$$

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

$$\begin{array}{rl}S(\rho )& =0\\ S(S^i)& =\rho a^i\\ S(e)& =S_i{a}^i,\end{array}$$

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