Detailed Description

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

Base class of FEPointEvaluation and FEFacePointEvaluation. This class needs usually not be called in user code and does not have any public constructor. The usage is through the class FEPointEvaluation/FEFacePointEvaluation instead.

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

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.

Definition at line 1750 of file fe_point_evaluation.h.

)
protected

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

Parameters

feThe FiniteElement object that is used for the evaluation, which is typically the same on all cells to be evaluated.
first_selected_componentFor multi-component FiniteElement objects, this parameter allows to select a range of n_components components starting from this parameter.

inline

Return the value at quadrature point number point_index after a call to FEPointEvaluation::evaluate() with EvaluationFlags::values set, or the value that has been stored there with a call to FEPointEvaluationBase::submit_value(). If the object is vector-valued, a vector-valued return argument is given.

void FEPointEvaluationBase< n_components_, dim, spacedim, Number >::submit_value ( const value_type value,
const unsigned int  point_index 
)
inline

Write a value to the field containing the values on points with component point_index. Access to the same field as through get_value().

inline

Return the gradient in real coordinates at the point with index point_index after a call to FEPointEvaluation::evaluate() with EvaluationFlags::gradients set, or the gradient that has been stored there with a call to FEPointEvaluationBase::submit_gradient(). The gradient in real coordinates is obtained by taking the unit gradient (also accessible via get_unit_gradient()) and applying the inverse Jacobian of the mapping. If the object is vector-valued, a vector-valued return argument is given.
