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 optional iterator to the cell containing the particles. Not all callers will know the cell of the particles, but providing the cell when known speeds up the interpolation significantly. |
- Returns
- A vector with as many entries as
positions. Every entry is a vector of interpolated particle properties at this position.
Implemented in aspect::Particle::Interpolator::QuadraticLeastSquares< dim >, aspect::Particle::Interpolator::BilinearLeastSquares< dim >, aspect::Particle::Interpolator::NearestNeighbor< dim >, aspect::Particle::Interpolator::CellAverage< dim >, and aspect::Particle::Interpolator::HarmonicAverage< dim >.
