Member Function Documentation

◆ ApplyInverseTransportOperator() [1/2]

void lbs::SweepWGSContext< Mat, Vec, KSP >::ApplyInverseTransportOperator ( int scope )

virtual

With a right-hand side built. This routine applies the inverse of the transport operator to this right-hand side.

Implements lbs::WGSContext< MatType, VecType, SolverType >.

Definition at line 107 of file sweep_wgs_context.cc.

◆ ApplyInverseTransportOperator() [2/2]

template<class MatType , class VecType , class SolverType >

void lbs::SweepWGSContext< MatType, VecType, SolverType >::ApplyInverseTransportOperator ( int scope )

overridevirtual

This operation applies the inverse of the transform operator in the form Ay = x where the the vector x's underlying implementing is always LBS's q_moments_local vextor.

Implements lbs::WGSContext< MatType, VecType, SolverType >.

◆ PostSolveCallback() [1/2]

void lbs::SweepWGSContext< Mat, Vec, KSP >::PostSolveCallback ( )

virtual

This method implements an additional sweep for two reasons: The first is to compute balance parameters, and the second is to allow for the calculation of proper angular fluxes. The latter is needed because some krylov methods do not necessarily provide the true angular flux at each iteration.

Reimplemented from lbs::WGSContext< MatType, VecType, SolverType >.

Definition at line 130 of file sweep_wgs_context.cc.

◆ PostSolveCallback() [2/2]

template<class MatType , class VecType , class SolverType >

void lbs::SweepWGSContext< MatType, VecType, SolverType >::PostSolveCallback ( )

overridevirtual

Reimplemented from lbs::WGSContext< MatType, VecType, SolverType >.

◆ PreSetupCallback() [1/2]

void lbs::SweepWGSContext< Mat, Vec, KSP >::PreSetupCallback ( )

virtual

General print out of information.

Reimplemented from lbs::WGSContext< MatType, VecType, SolverType >.

Definition at line 21 of file sweep_wgs_context.cc.

◆ PreSetupCallback() [2/2]

template<class MatType , class VecType , class SolverType >

void lbs::SweepWGSContext< MatType, VecType, SolverType >::PreSetupCallback ( )

overridevirtual

Reimplemented from lbs::WGSContext< MatType, VecType, SolverType >.

◆ SetPreconditioner() [1/2]

void lbs::SweepWGSContext< Mat, Vec, KSP >::SetPreconditioner ( KSP & solver )

Sets the preconditioner application function.

Definition at line 52 of file sweep_wgs_context.cc.

◆ SetPreconditioner() [2/2]

template<class MatType , class VecType , class SolverType >

void lbs::SweepWGSContext< MatType, VecType, SolverType >::SetPreconditioner ( SolverType & solver )

overridevirtual

Reimplemented from lbs::WGSContext< MatType, VecType, SolverType >.

◆ SystemSize() [1/2]

std::pair< int64_t, int64_t > lbs::SweepWGSContext< Mat, Vec, KSP >::SystemSize ( )

virtual

For sweeping we add lagged angular fluxes to the size of the vectors.

Implements lbs::WGSContext< MatType, VecType, SolverType >.

Definition at line 72 of file sweep_wgs_context.cc.

◆ SystemSize() [2/2]

template<class MatType , class VecType , class SolverType >

std::pair< int64_t, int64_t > lbs::SweepWGSContext< MatType, VecType, SolverType >::SystemSize ( )

overridevirtual
