template<int dim>

virtual std::vector<std::vector<double> > aspect::Particle::Interpolator::Interface< dim >::properties_at_points ( const ParticleHandler< dim > &  particle_handler, const std::vector< Point< dim >> &  positions, const ComponentMask &  selected_properties, const typename parallel::distributed::Triangulation< dim >::active_cell_iterator &  cell  ) const

pure virtual

Perform an interpolation of the properties of the particles in this cell onto a vector of positions in this cell. Implementations of this function must return a vector of a vector of doubles with as many entries as positions in positions. Each entry is a vector with as many entries as there are particle properties in this computation. All in selected_properties selected components will be filled with computed properties, all other components are not filled (or filled with invalid values).

Parameters

[in]	particle_handler	Reference to the particle handler that allows accessing the particles in the domain.
[in]	positions	The vector of positions where the properties should be evaluated.
[in]	selected_properties	A component mask that determines which particle properties are interpolated in this function.
[in]	cell	An iterator to the cell containing the positions.

Returns

A vector with as many entries as positions. Each entry is a vector of interpolated particle properties at this position. This property vector has as many entries as there are particle properties, however entries that have not been selected in selected_properties are filled with signalling NaNs.

Implemented in aspect::Particle::Interpolator::QuadraticLeastSquares< dim >, aspect::Particle::Interpolator::DistanceWeightedAverage< dim >, aspect::Particle::Interpolator::BilinearLeastSquares< dim >, aspect::Particle::Interpolator::NearestNeighbor< dim >, aspect::Particle::Interpolator::CellAverage< dim >, and aspect::Particle::Interpolator::HarmonicAverage< dim >.
