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

Vector<Real> AMRLevelMG::computeResidualNorm (  int    normType )  const

compute and return norm of internal data m_resid.

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

Define AMRLevelMG from the inputs. The AMRLevelMG will only work for the input AMRSolver. A LevelMG is created.

void AMRLevelMG::downSweep (  Vector< LevelData< FArrayBox > * > &    a_phiLevel, const Vector< LevelData< FArrayBox > * > &    a_rhsLevel )

Sweep down v-cycle

void AMRLevelMG::incrementFRFine (  Vector< LevelData< FArrayBox > * > &    a_phiLevel )  [protected]

void AMRLevelMG::initFRCoarse (  Vector< LevelData< FArrayBox > * > &    a_phiLevel )  [protected]

bool AMRLevelMG::isDefined (    )  const

LevelOp* AMRLevelMG::levelOpPtr (    )  const

void AMRLevelMG::reflux (  Vector< LevelData< FArrayBox > * > &    a_phiLevel, LevelData< FArrayBox > &    a_Lofphi )  [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 )

Sweep up multigrid v-cycle. Computes residual on
