Detailed Description

template<class ParticleType, class IType>
class TriMesh_PIS_EB< ParticleType, IType >

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

Here is the call graph for this function:

template<class ParticleType, class IType>

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

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.

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.
