Detailed Description

template<int dim>
class aspect::Particle::Interpolator::QuadraticLeastSquares< dim >

Return the properties of all particles of the given cell by using a least squares projection onto the space of quadratic functions.

const std::vector< Point< dim >> &  positions,
const ComponentMask &  selected_properties,
const typename parallel::distributed::Triangulation< dim >::active_cell_iterator &  cell 
) const
overridevirtual

Implements aspect::Particle::Interpolator::Interface< dim >.

§ declare_parameters()

template<int dim>
static void aspect::Particle::Interpolator::QuadraticLeastSquares< dim >::declare_parameters ( ParameterHandler &  prm)
static

Member Data Documentation

§ fallback_interpolator

template<int dim>
Interpolator::CellAverage<dim> aspect::Particle::Interpolator::QuadraticLeastSquares< dim >::fallback_interpolator
private

Use the cell average interpolator in case the quadratic least squares interpolator fails due to a lack of particles.

Definition at line 83 of file quadratic_least_squares.h.

§ use_quadratic_least_squares_limiter

template<int dim>
ComponentMask aspect::Particle::Interpolator::QuadraticLeastSquares< dim >::use_quadratic_least_squares_limiter
private

Enables a limiting scheme that prevents overshoot and undershoot of interpolated particles based upon the range of property values found in the area of the cell.

Definition at line 90 of file quadratic_least_squares.h.

§ use_boundary_extrapolation

template<int dim>
ComponentMask aspect::Particle::Interpolator::QuadraticLeastSquares< dim >::use_boundary_extrapolation
private

Enables a linear extrapolation of boundary values for the limiting scheme
