Member Function Documentation

◆ 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.

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 >

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
commDirA communication direction pointing toward an adjacent coarse block
