Detailed Description

Helper term to keep smoothing length constant during the simulation.

The smoothing length is currently stored as the 4th component of the position vectors. Because of that, it is necessary to either provide an equation evolving smoothing length in time (see AdaptiveSmoothingLength), or use this equation to set all derivatives of smoothing length to zero.

Attention: If neither of these equations are used and the smoothing length is not explicitly handled by the solver or timestepping, the behavior might by unexpected and possibly leads to errors. This issue will be resolved in the future.

◆ create()

void ConstSmoothingLength::create	(	Storage &	storage,
		IMaterial &	material
	)		const

overridevirtual

Creates all quantities needed by the term using given material.

Called once for every body in the simulation.

Implements IEquationTerm.

Definition at line 466 of file EquationTerm.cpp.

◆ finalize()

void ConstSmoothingLength::finalize	(	IScheduler &	scheduler,
		Storage &	storage,
		const Float	t
	)

overridevirtual

Computes all the derivatives and/or quantity values based on accumulated derivatives.

Called every time step after derivatives are evaluated and saved to storage.

Implements IEquationTerm.

Definition at line 457 of file EquationTerm.cpp.

◆ initialize()

void ConstSmoothingLength::initialize	(	IScheduler &	scheduler,
		Storage &	storage,
		const Float	t
	)

overridevirtual

Initialize all the derivatives and/or quantity values before derivatives are computed.

Called at the beginning of every time step. Note that derivatives need not be zeroed out manually, this is already done by timestepping (for derivatives of quantities) and solver (for accumulated values).

Implements IEquationTerm.

Definition at line 453 of file EquationTerm.cpp.

◆ setDerivatives()

void ConstSmoothingLength::setDerivatives	(	DerivativeHolder &	derivatives,
		const RunSettings &	settings
	)

overridevirtual

Sets derivatives required by this term.

The derivatives are then automatically evaluated by the solver, the equation term can access the result in finalize function. This function is called once for each thread at the beginning of the run.

Implements IEquationTerm.
