Detailed Description

class which manages data and operations on a level for AMRSolver

AMRLevelMG manages the operations on a level for AMRSolver. AMRSolver contains a vector of AMRLevelMG's (one for each level). This class should be considered internal to AMRSolver and should not be considered part of the Chombo API.


Constructor & Destructor Documentation

AMRLevelMG::AMRLevelMG  
 

AMRLevelMG::~AMRLevelMG  
 

AMRLevelMG::AMRLevelMG const AMRSolver *const    a_parent,
int    a_level,
const LevelOp *const    a_opin,
int    ncomp = 1
 

Define AMRLevelMG from the inputs.


Member Function Documentation

void AMRLevelMG::applyAMROperator Vector< LevelData< FArrayBox > * > &    a_phiLevel,
LevelData< FArrayBox > &    Lofphi
 

Complete, 3-level operator. Applies operator with inhomogeneous coarse-fine boundary conditions (and inhomogeneous domain boundary conditions. Refluxing is used to compute the operator at coarse-fine boundaries.

void AMRLevelMG::applyAMROperatorHphys Vector< LevelData< FArrayBox > * > &    a_phiLevel,
LevelData< FArrayBox > &    LofPhi
 

Complete, 3-level operator with homogeneous physical boundary conditions. Applies operator with inhomogeneous physical boundary conditions. Refluxing is used to compute the operator at coarse-fine boundaries.

void AMRLevelMG::clearMemory   [protected]
 

void AMRLevelMG::computeAMRResidual LevelData< FArrayBox > &    a_resid,
Vector< LevelData< FArrayBox > * > &    a_phiLevel,
const Vector< LevelData< FArrayBox > * > &    a_rhsLevel
 

Compute complete, 3-level residual and return it in the argument LevelData<FArrayBox>

void AMRLevelMG::computeAMRResidual Vector< LevelData< FArrayBox > * > &    a_phiLevel,
const Vector< LevelData< FArrayBox > * > &    a_rhsLevel
 

Compute complete, 3-level residual and put it into local data m_resid

void AMRLevelMG::computeAMRResidualHphys Vector< LevelData< FArrayBox > * > &    a_phiLevel,
const Vector< LevelData< FArrayBox > * > &    a_rhsLevel
 

Compute complete, 3-level residual with homogeneous physical BCs and inhomogeneous C/F BCs and put it into local data m_resid

Vector<Real> AMRLevelMG::computeNorm const LevelData< FArrayBox > &    a_mfinput,
int    a_normType
const [protected]
 

Vector<Real> AMRLevelMG::computeResidualNorm int    normType const
 

compute and return norm of internal data m_resid.

void AMRLevelMG::crseCorrect LevelData< FArrayBox > &    a_soln,
const LevelData< FArrayBox > &    a_crseCorr,
int    a_nref
[protected]
 

void AMRLevelMG::define const AMRSolver *const    a_parent,
int    a_level,
const LevelOp *const    a_opin,
int    ncomp = 1

[protected]
 

void AMRLevelMG::setDefaultValues   [protected]
 

void AMRLevelMG::setnumSmoothDown int    a_numSmoothDown
 

Set number of multigrid smoothings on way down V-cycle; Default == 4.

void AMRLevelMG::setnumSmoothUp int    a_numSmoothUp
 

Set number of multigrid smoothings on way up V-cycle; Default == 4.

void AMRLevelMG::smooth LevelData< FArrayBox > &    a_soln,
const LevelData< FArrayBox > &    rhs
[protected]
 

void AMRLevelMG::upSweep Vector< LevelData< FArrayBox > * > &    a_phiLevel,
const Vector< LevelData< FArrayBox > * > &    a_rhsLevel
