Detailed Description

template<class DimI>
struct ddc::ConstantExtrapolationRule< DimI >

A functor for describing a spline boundary value by a constant extrapolation for 1D evaluator.

To define the value of a function on B-splines out of the domain, we here use a constant extrapolation on the edge.

Constructor & Destructor Documentation

ConstantExtrapolationRule()

template<class DimI >

ddc::ConstantExtrapolationRule< DimI >::ConstantExtrapolationRule ( ddc::Coordinate< DimI >  eval_pos )

inlineexplicit

Instantiate a ConstantExtrapolationRule.

The boundary value will be the same as at the coordinate eval_pos given.

Parameters

[in]

eval_pos

Coordinate inside the domain where we will evaluate each points outside the domain.

KOKKOS_FUNCTION double ddc::ConstantExtrapolationRule< DimI >::operator() ( CoordType  pos, ddc::ChunkSpan< double const, ddc::DiscreteDomain< BSplines >, Layout, MemorySpace > const  spline_coef  ) const

inline

Get the value of the function on B-splines at a coordinate outside the domain.

Parameters

[in]	pos	The coordinate where we want to evaluate the function on B-splines.
[in]	spline_coef	The coefficients of the function on B-splines.

Returns

A double with the value of the function on B-splines evaluated at the coordinate.
