bool Mesh2D_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 edge/corner (v[0]) and particle (v[1]) ids, the 3rd an indicator if tri edge (v[2]==1)or corner (v[2]==2) interaction. If there is no 3rd value or it is not 1 (edge), "false" is returned.

Parameters

v	vector of particle ids

Warning: log(N)

void Mesh2D_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.

template<class ParticleType , class IType >

void Mesh2D_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 edge (pids[2]==1)or corner (pids[2]==2) interaction. If there is no 3rd value or it is not in [1,2], nothing happens.

Parameters

pids	the particle Ids
