Member Function Documentation

◆ abortTimeStep()

void Momentum_Euler::abortTimeStep ( )

overridevirtual

Reinitialize what must be.

This method is called when a time step is abandoned, for example because the calculation has diverged. So you must clean up what could pollute the new resolution.

Exceptions

WrongContext

Reimplemented from Equation_base.

Definition at line 137 of file Momentum_Euler.cpp.

◆ alpha_res()

double Momentum_Euler::alpha_res ( ) const

Definition at line 289 of file Momentum_Euler.cpp.

◆ calculer_pas_de_temps()

double Momentum_Euler::calculer_pas_de_temps ( ) const

overridevirtual

Calculation of the next time step.

Returns the inverse of the sum of the inverses of the time steps calculated by the operators. These time steps are those for the explicit Euler scheme. The time step is not limited by dt_max, this is done in corriger_dt_calcule

Returns: (double) inverse of the sum of the inverses of the time steps calculated by the operators
