computeBitMask()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::computeBitMask

private

Computes the partial coalescence bit mask on the mask field.

Assumes that all flags are already registered at the field, and that the field has been initialized to zero.

getMaskField() [1/2]

template<typename LatticeStorageSpecification_T >

PartialCoalescenceMaskField& walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::getMaskField ( )

inline

getMaskField() [2/2]

template<typename LatticeStorageSpecification_T >

const PartialCoalescenceMaskField& walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::getMaskField ( ) const

inline

haveSmallestIdInIntersection()

template<typename LatticeStorageSpecification_T >

bool walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::haveSmallestIdInIntersection ( Vector3< cell_idx_t >  cornerDir )

inlineprivate

Determines whether the current block has the smallest BlockID among all fine blocks of a given intersection volume.

Template Parameters

LatticeStorageSpecification_T

Parameters

cornerDir

Returns

operator!=()

template<typename LatticeStorageSpecification_T >

bool walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::operator!= ( const NonuniformCommData< LatticeStorageSpecification_T > &  other )

prepareIntervals()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::prepareIntervals ( )

private

registerFlags()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::registerFlags

private

setFlagOnInterval()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::setFlagOnInterval ( const CellInterval &  ci, const uint_t  fIdx  )

private

setupBitMaskSlice()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::setupBitMaskSlice ( stencil::Direction  commDir, stencil::Direction  streamDir  )

inlineprivate

setupCornerSkippingOrigins()

template<typename LatticeStorageSpecification_T >

void walberla::lbm_generated::NonuniformCommData< LatticeStorageSpecification_T >::setupCornerSkippingOrigins ( stencil::Direction  commDir )

inlineprivate

Sets up the feasible space for the given communication direction.

Additionally to the field interior, marks every ghost layer slice corresponding to an adjacent coarse block, and the corresponding corner as feasible, if that corner also belongs to a coarse block and the current block has the smallest BlockID participating in the intersection.

Parameters

commDir

A communication direction pointing toward an adjacent coarse block
