Detailed Description

This class defines an interface for computing quantities needed for deciding on a stable time step for high-order mapped AMR algorithms.

Constructor & Destructor Documentation

AMRLevelMappedStabilityStrategy() [1/3]

AMRLevelMappedStabilityStrategy::AMRLevelMappedStabilityStrategy ( Real  a_stabilityFactor )

explicit

Base class strategy constructor. Must be called by all subclasses.

Parameters

a_stabilityFactor

The factor representing the broadest height of the region of stability for the time integrator of interest.

~AMRLevelMappedStabilityStrategy()

virtual AMRLevelMappedStabilityStrategy::~AMRLevelMappedStabilityStrategy ( )

virtual

Destructor.

Member Function Documentation

maxTimeStep()

Real AMRLevelMappedStabilityStrategy::maxTimeStep	(	const ProblemDomain &	a_problem_domain,
		const DisjointBoxLayout &	a_grids,
		const LevelGridMetrics *const	a_gridMetrics,
		const MOLPhysics &	a_physics,
		const MappedLevelData &	a_data,
		Real	a_dx,
		Real	a_time
	)		const

This returns the maximum allowable time step (without a CFL safety factor.

Parameters

a_data	The mapped grid data to be used in determining the time step.
a_dx	The grid spacing that determines the time step.
a_time	The time at which the time step is computed.

maxWaveSpeed()

virtual Real AMRLevelMappedStabilityStrategy::maxWaveSpeed ( const ProblemDomain &  a_problem_domain, const DisjointBoxLayout &  a_grids, const LevelGridMetrics *const  a_gridMetrics, const MOLPhysics &  a_physics, const MappedLevelData &  a_data, Real  a_dx, Real  a_time  ) const

pure virtual

Override this method to determine the maximum wave speed on the computational domain.

Parameters

a_data

The mapped grid data to be used in determining the wave speed.

clone()

virtual AMRLevelMappedStabilityStrategy* AMRLevelMappedStabilityStrategy::clone ( ) const

pure virtual

Override this method to create a new AMRLevelMappedStabilityStrategy instance.

operator=()

AMRLevelMappedStabilityStrategy& AMRLevelMappedStabilityStrategy::operator= ( const AMRLevelMappedStabilityStrategy &  )
