Member Function Documentation

◆ create()

void CorrectionTensor::create ( Accumulated & results )

overridevirtual

Emplace all needed buffers into shared storage.

Called only once at the beginning of the run.

Implements IDerivative.

Definition at line 17 of file Derivative.cpp.

◆ evalNeighs()

void CorrectionTensor::evalNeighs	(	Size	idx,
		ArrayView< const Size >	neighs,
		ArrayView< const Vector >	grads
	)

overridevirtual

Compute derivatives of given particle.

Derivatives are computed by summing up pair-wise interaction between the given particle and its neighbours. Derivatives of the neighbours should not be modified by the function. Note that the given particle is NOT included in its own neighbours.

Parameters

idx	Index of the first interacting particle.
neighs	Array containing all neighbours of idx-th particle.
grads	Computed gradients of the SPH kernel for each particle pair.

Implements IDerivative.

Definition at line 36 of file Derivative.cpp.

◆ initialize()

void CorrectionTensor::initialize	(	const Storage &	input,
		Accumulated &	results
	)

overridevirtual

Initialize derivative before iterating over neighbours.

All pointers and arrayviews used to access storage quantities must be initialized in this function, as they may have been invalidated.

Parameters

input	Storage containing all the input quantities from which derivatives are computed. This storage is shared for all threads.
results	Thread-local storage where the computed derivatives are saved.

Implements IDerivative.

Definition at line 22 of file Derivative.cpp.

◆ phase()

DerivativePhase CorrectionTensor::phase ( ) const

overridevirtual

Returns the phase of the derivative.

As long as the derivative does not depend on other derivatives, it shall return DerivativePhase::EVALUATION. Auxiliary derivatives, computing helper term that are later used for evaluation of other derivatives, belong to phase DerivativePhase::PRECOMPUTE.

Implements IDerivative.
