Detailed Description

This module contains classes and functions related to solving the compressible Euler equations coupled to a Poisson problem for the electrostatic potential.

Enumeration Type Documentation

GaussLawRestartStrategy

enum ryujin::EulerPoisson::GaussLawRestartStrategy : dealii::types::boundary_id

Controls the chosen Gauss law restart strategy.

Enumerator
no_restart	Initialize the potential by solving $$ -\Delta \varphi = \alpha (\rho + \rho_b) $$ once at the first timestep. Then, solve $$ -\partial_t \Delta \varphi = - \alpha \nabla \cdot \boldsymbol m + \partial_t \rho_b $$ at each parabolic substep. Do not restart the Gauss law. This is the default strategy.
full_restart	Initialize the potential by solving $$ -\Delta \varphi = \alpha (\rho + \rho_b) $$ once at the first timestep. Then, solve $$ -\partial_t \Delta \varphi = - \alpha \nabla \cdot \boldsymbol m + \partial_t \rho_b $$ at each parabolic substep. Finally, at the beginning of each subsequent time step, restart the Gauss law at the beginning of each time step by solving again $$ -\Delta \varphi = \alpha (\rho + \rho_b). $$
correction	Solve $$ -\partial_t \Delta \varphi = -\alpha \nabla \cdot \boldsymbol m \partial_t \rho_b $$ at each parabolic substep. Then, correct the Gauss law violation by artificially relaxing the kinetic energy. FIXME documentation
static_no_restart	Initialize the potential by solving $$ -\Delta \varphi = \alpha (\rho + \rho_b) $$ once at the first timestep. Afterwards, do not update the potential any more.
static_full_restart	Solve $$ -\Delta \varphi = \alpha (\rho + \rho_b) $$ at the beginning of each timestep. Do not update the potential during a parabolic substep.
