◆ exchange_boundary()

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::exchange_boundary	(	int	dim,
		int	dir
	)

private

helper function to do the actual shifting of values in exchange()

Parameters

dim	dimension, 0->x, 1->y, 2->z
dir	direction, 1->up, -1->down

References console, esys::lsm::bpu::iter(), and Console::XDebug().

Here is the call graph for this function:

◆ isIn()

template<class ParticleType , class IType >

bool TriMesh_PIS_EB< ParticleType, IType >::isIn ( const vector< int > & v )

virtual

Check if an interaction is in this PIS. The first 2 values in the vector are expected to be the tri/edge/corner (v[0]) and particle (v[1]) ids, the 3rd an indicator if tri (v[2]==0),edge (v[2]==1)or corner (v[2]==2) interaction. If there is no 3rd value or it is not 0 (tri), "false" is returned.

Parameters

v	vector of particle ids

Warning: log(N)

Implements AParallelInteractionStorage.

References console, and Console::Error().

Here is the call graph for this function:

◆ rebuild()

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::rebuild

virtual

Rebuild interactions after moving particles or interactions between processes. Set particle pointers accordig to particle IDs and remove interactionw which include unavailable particles.

Implements AParallelInteractionStorage.

References console, ParallelParticleArray< T >::getParticlePtrByIndex(), NULL, and Console::XDebug().

Here is the call graph for this function:

◆ saveSnapShotData()

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::saveSnapShotData ( std::ostream & oStream )

virtual

save snapshot (i.e. viz/postprocess) data

Parameters

oStream a reference to the stream where the data is written

Reimplemented from AParallelInteractionStorage.

◆ setTimeStepSize()

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::setTimeStepSize ( double dt )

virtual

Implements AParallelInteractionStorage.

◆ tryInsert() [1/2]

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::tryInsert ( const typename IType::TriIntType & In )

virtual

References ParallelParticleArray< T >::getParticlePtrByIndex(), and NULL.

Here is the call graph for this function:

◆ tryInsert() [2/2]

template<class ParticleType , class IType >

void TriMesh_PIS_EB< ParticleType, IType >::tryInsert ( const vector< int > & pids )

virtual

Insert interactions newly created from particle Ids and parameters. If insertion is impossible because the interaction is already in, or one of the particles is not in the associated PPA nothing happens. Check if an interaction is in this PIS. The first 2 values in the vector are expected to be the tri/edge/corner (pids[0]) and particle (pids[1]) ids, the 3rd an indicator if tri (pids[2]==0),edge (pids[2]==1)or corner (pids[2]==2) interaction. If there is no 3rd value or it is not in [0,1,2], nothing happens.

Parameters

pids	the particle Ids
