Detailed Description

Todo:: Integrate with other time stepping classes or remove? A small convenience class providing a consistent global time to the PDE solver classes.

This isn't technically a singleton, as it's implemented with static data and methods.

void PdeSimulationTime::SetPdeTimeStepAndNextTime	(	double	timestep,
		double	next_time
	)

static

Set the current PDE timestep.

The method checks that next_time ~= mTime + timestep

Parameters

timestep	the current timestep
next_time	the next time (as given by the PDE time stepper).

void PdeSimulationTime::SetTime ( double time )

static

Set the current time.

Parameters

time	the current time

Member Data Documentation

double PdeSimulationTime::mNextTime

staticprivate

The next time (from the original PDE time-stepper). mNextTime ~= mTime + mPdeTimeStep. Note that this is stored explicitly because if we do the addition then the answer will be off by mTime*DBL_EPSILON.

Definition at line 92 of file PdeSimulationTime.hpp.

double PdeSimulationTime::mPdeTimeStep

staticprivate

The timestep used in the PDE solve.

double PdeSimulationTime::mPdeTimeStepInverse
