◆ set_state_in_checkpoint()

void amrex::AmrLevel::set_state_in_checkpoint ( Vector< int > & state_in_checkpoint )

Old checkpoint may have different number of states than the new source code.

◆ SetLevelDirectoryCreated()

void amrex::AmrLevel::SetLevelDirectoryCreated ( bool ldc )

inlinenoexcept

Set if the Level_ directory was created or to clear the value. CreateLevelDirectory sets levelDirectoryCreated = true.

Function to set physical boundary conditions.

◆ setPlotVariables()

void amrex::AmrLevel::setPlotVariables ( )

virtual

Modify list of variables to be plotted.

inlinenoexcept

Sets a new value for the post-timestep regrid trigger.

◆ setSmallPlotVariables()

void amrex::AmrLevel::setSmallPlotVariables ( )

virtual

Modify list of variables to be plotted.

◆ setTimeLevel()

void amrex::AmrLevel::setTimeLevel	(	Real	time,
		Real	dt_old,
		Real	dt_new
	)

virtual

Set the time levels of state data.

◆ storeRKCoarseData()

template<std::size_t order>

void amrex::AmrLevel::storeRKCoarseData	(	int	state_type,
		Real	time,
		Real	dt,
		MultiFab const &	S_old,
		Array< MultiFab, order > const &	rkk
	)

private

◆ thePlotFileType()

virtual std::string amrex::AmrLevel::thePlotFileType ( ) const

inlinevirtual

A string written as the first item in writePlotFile() at level zero. It is so we can distinguish between different types of plot files. This default "HyperCLaw-V1.1" is for VisIt software and some of our internal postprocessing routines.

◆ UpdateDistributionMaps()

void amrex::AmrLevel::UpdateDistributionMaps ( DistributionMapping & dmap )

Update the distribution maps in StateData based on the size of the map.

◆ which_time()

AmrLevel::TimeLevel amrex::AmrLevel::which_time	(	int	state_indx,
		Real	time
	)		const

noexcept

Returns one the TimeLevel enums. Asserts that time is between AmrOldTime and AmrNewTime.

◆ WorkEstType()

virtual int amrex::AmrLevel::WorkEstType ( )

inlinevirtual

Which state data type is for work estimates? -1 means none.

◆ writePlotFile()

void amrex::AmrLevel::writePlotFile	(	const std::string &	dir,
		std::ostream &	os,
		VisMF::How	how = `VisMF::NFiles`
	)

virtual

Write plot file stuff to specified directory.

◆ writePlotFilePost()

void amrex::AmrLevel::writePlotFilePost	(	const std::string &	dir,
		std::ostream &	os
	)

virtual

Do post-plotfile work to avoid synchronizations while writing the amr hierarchy.

◆ writePlotFilePre()

void amrex::AmrLevel::writePlotFilePre	(	const std::string &	dir,
		std::ostream &	os
	)

virtual

Do pre-plotfile work to avoid synchronizations while writing the amr hierarchy.

◆ writePlotNow()

bool amrex::AmrLevel::writePlotNow ( )

virtual

Does the AmrLevel want Amr to write a plotfile now?

◆ writeSmallPlotFile()

virtual void amrex::AmrLevel::writeSmallPlotFile	(	const std::string &	,
		std::ostream &	,
		VisMF::How	= `VisMF::NFiles`
	)

inlinevirtual

Write small plot file stuff to specified directory.

◆ writeSmallPlotNow()

bool amrex::AmrLevel::writeSmallPlotNow ( )

virtual

Does the AmrLevel want Amr to write a small plotfile now?
