Detailed Description

Boundary condition that nulls all highest derivates of selected particles.

Term can freeze particles close to the boundary and/or particles of given body or list of bodies. This will cause the particles to keep quantity values given by their initial conditions and move with initial velocity. The 'frozen' particles affect other particles normally and contribute to all integrals, such as total mometum or energy.

Constructor & Destructor Documentation

FrozenParticles() [1/2]

FrozenParticles::FrozenParticles ( )

default

Constructs boundary conditions with no particles frozen.

These can be later added using freeze function.

~FrozenParticles()

FrozenParticles::~FrozenParticles ( )

default

FrozenParticles() [2/2]

FrozenParticles::FrozenParticles	(	SharedPtr< IDomain >	domain,
		const Float	radius
	)

Constructs boundary conditions with frozen particles near boundary.

Parameters

domain	Domain defining the boundary
radius	Search radius (in units of smoothing length) up to which the particles will be frozen.

Definition at line 194 of file Boundary.cpp.

Member Function Documentation

finalize()

void FrozenParticles::finalize ( Storage &  storage )

overridevirtual

Applies the boundary conditions after the derivatives are computed.

Called every time step after equations are evaluated (finalized).

Implements IBoundaryCondition.

Reimplemented in WindTunnel.

Definition at line 208 of file Boundary.cpp.

freeze()

void FrozenParticles::freeze

(

const Size

flag

)

Adds body ID particles of which shall be frozen by boundary conditions.

Definition at line 199 of file Boundary.cpp.

initialize()

virtual void FrozenParticles::initialize ( Storage &  UNUSEDstorage )

inlineoverridevirtual

Reimplemented in WindTunnel.

Definition at line 192 of file Boundary.h.

thaw()

void FrozenParticles::thaw

(

const Size

flag

)

Remove a body from the list of frozen bodies.

Remove a body from the list of frozen bodies. If the body is not on the list, nothing happens.

If the body is not on the list, nothing happens.
