number of reduction levels (not including the coarsest level)

Definition at line 73 of file HypreMGR.hpp.

Constructor & Destructor Documentation

MGRStrategyBase()

template<int NLEVEL>

geos::hypre::mgr::MGRStrategyBase< NLEVEL >::MGRStrategyBase ( HYPRE_Int const  numBlocks )

inlineexplicitprotected

Constructor.

Parameters

numBlocks

number of blocks

Definition at line 105 of file HypreMGR.hpp.

Member Function Documentation

setDisplacementAMG()

template<int NLEVEL>

void geos::hypre::mgr::MGRStrategyBase< NLEVEL >::setDisplacementAMG ( HyprePrecWrapper &  solver, integer const &  separateComponents  )

inlineprotected

Set up BoomerAMG to perform the solve for the displacement system.

Parameters

solver	the solver wrapper
separateComponents	flag controlling the use of the separate displacement component (SDC) approximation

Definition at line 174 of file HypreMGR.hpp.

setILUCoarseSolver()

template<int NLEVEL>

void geos::hypre::mgr::MGRStrategyBase< NLEVEL >::setILUCoarseSolver ( HyprePrecWrapper &  solver )

inlineprotected

Parameters

solver

Definition at line 277 of file HypreMGR.hpp.

setMechanicsFSolver()

template<int NLEVEL>

void geos::hypre::mgr::MGRStrategyBase< NLEVEL >::setMechanicsFSolver ( HyprePrecWrapper &  precond, HypreMGRData &  mgrData, integer const &  separateComponents  )

inlineprotected

Set up BoomerAMG to perform the mechanics F-solve for the first F-relaxation.

Parameters

precond	the preconditioner wrapper
mgrData	auxiliary MGR data
separateComponents	flag controlling the use of the separate displacement component (SDC) approximation

Note

This function should be rethought once MGR allows for customizing boomerAMG (or any other solver) for F-relaxation at any level

Definition at line 265 of file HypreMGR.hpp.
