Detailed Description

template<int n_components_, int dim, int spacedim = dim, typename Number = double>
class FEPointEvaluation< n_components_, dim, spacedim, Number >

This class provides an interface to the evaluation of interpolated solution values and gradients on cells on arbitrary reference point positions. These points can change from cell to cell, both with respect to their quantity as well to the location. The two typical use cases are evaluations on non-matching grids and particle simulations.

The use of this class is similar to FEValues or FEEvaluation: The class is first initialized to a cell by calling FEPointEvaluation::reinit(cell, unit_points), with the main difference to the other concepts that the underlying points in reference coordinates need to be passed along. Then, upon call to evaluate() or integrate(), the user can compute information at the give points. Eventually, the access functions get_value() or get_gradient() allow to query this information at a specific point index.

The functionality is similar to creating an FEValues object with a Quadrature object on the unit_points on every cell separately and then calling FEValues::get_function_values or FEValues::get_function_gradients, and for some elements and mappings this is what actually happens internally. For specific combinations of Mapping and FiniteElement realizations, however, there is a much more efficient implementation that avoids the memory allocation and other expensive start-up cost of FEValues. Currently, the functionality is specialized for mappings derived from MappingQ and MappingCartesian and for finite elements with tensor product structure that work with the Matrix-free infrastructure module. In those cases, the cost implied by this class is similar (or sometimes even somewhat lower) than using FEValues::reinit(cell) followed by FEValues::get_function_gradients.

const FiniteElement< dim, spacedim > &  fe,
const UpdateFlags  update_flags,
const unsigned int  first_selected_component = 0 
)

Constructor.

Parameters
mappingThe Mapping class describing the actual geometry of a cell passed to the evaluate() function.
feThe FiniteElement object that is used for the evaluation, which is typically the same on all cells to be evaluated.
update_flagsSpecify the quantities to be computed by the mapping during the call of reinit(). During evaluate() or integrate(), this data is queried to produce the desired result (e.g., the gradient of a finite element solution).
first_selected_componentFor multi-component FiniteElement objects, this parameter allows to select a range of n_components components starting from this parameter.

)

Constructor to make the present class able to re-use the geometry data also used by other FEPointEvaluation objects.

This function multiplies the quantities passed in by previous submit_value() or submit_gradient() calls by the value or gradient of the test functions, and performs summation over all given points multiplied be the Jacobian determinant times the quadrature weight (JxW).

Parameters
[out]solution_valuesThis array will contain the result of the integral, which can be used to during cell->set_dof_values(solution_values, global_vector) or cell->distribute_local_to_global(solution_values, global_vector).

const EvaluationFlags::EvaluationFlags integration_flags,
const bool  sum_into_values = false
