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 topic. 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
.
