Detailed Description

template<typename Type>
class SphInterpolant< Type >

Object for computing interpolated values of quantities.

Quantity values or derivatives are interpolated using SPH kernel. If the point of interpolation lies outside of support of all SPH particles, the interpolated value is zero.

Template Parameters

Type	Value type of the quantity being interpolated.

Constructor & Destructor Documentation

SphInterpolant() [1/2]

template<typename Type >

SphInterpolant< Type >::SphInterpolant ( const Storage &  storage, const QuantityId  id, const OrderEnum  deriv, const RunSettings &  settings = RunSettings::getDefaults()  )

inline

Constructs the interpolation object from settings.

Definition at line 47 of file Interpolation.h.

SphInterpolant() [2/2]

template<typename Type >

SphInterpolant< Type >::SphInterpolant ( const Storage &  storage, const QuantityId  id, const OrderEnum  deriv, AutoPtr< IBasicFinder > &&  finder, LutKernel< 3 > &&  kernel  )

inline

Constructs the interpolation object given a neighbour finding object and a SPH kernel.

Parameters

finder	Object for finding neighbours. Overload of INeighbourFinder::findNeighbours taking a vector must be implemented. Parameter must not be nullptr.
kernel	SPH kernel used for interpolation.
id	Quantity values of which we wish to interpolate. The quantity must be stored in the storage.
deriv	Specifies whether to interpolate quantity values or its derivatives. For values, use OrderEnum::ZERO. If the first or second derivative is being interpolated, the quantity must be of corresponding order, checked by assert.
