Constructor & Destructor Documentation

◆ NewtonianFluidMaterial()

oofem::NewtonianFluidMaterial::NewtonianFluidMaterial	(	int	n,
		Domain *	d )

inline

Constructor. Creates material with given number, belonging to given domain.

Parameters

n	Material number.
d	Domain to which new material will belong.

Definition at line 67 of file newtonianfluid.h.

References oofem::FluidDynamicMaterial::FluidDynamicMaterial().

Member Function Documentation

◆ checkConsistency()

int oofem::NewtonianFluidMaterial::checkConsistency ( void )

overridevirtual

Allows programmer to test some internal data, before computation begins. For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns: Nonzero if receiver is consistent.

Todo: Fix this, checkConsistency shouldn't be a replacement for "post-initialization" but should be completely optional.

Reimplemented from oofem::Material.

FloatArrayF< 6 > oofem::NewtonianFluidMaterial::computeDeviatoricStress3D	(	const FloatArrayF< 6 > &	eps,
		GaussPoint *	gp,
		TimeStep *	tStep ) const

overridevirtual

Computes the deviatoric stress vector from given strain.

Parameters

answer	Deviatoric stress.
gp	Integration point.
eps	Strain-rate.
tStep	Time step.

Implements oofem::FluidDynamicMaterial.

◆ computeTangent3D()

FloatMatrixF< 6, 6 > oofem::NewtonianFluidMaterial::computeTangent3D	(	MatResponseMode	mode,
		GaussPoint *	gp,
		TimeStep *	tStep ) const

overridevirtual

Computes the deviatoric stiffness; \( \frac{\partial\sigma_{\mathrm{dev}}}{\partial \epsilon_{\mathrm{dev}}}\).

Parameters

answer	Stiffness matrix.
mode	Mode of result.
gp	Integration point.
tStep	Time step.

◆ CreateStatus()

std::unique_ptr< MaterialStatus > oofem::NewtonianFluidMaterial::CreateStatus ( GaussPoint * gp ) const

overridevirtual

Creates new copy of associated status and inserts it into given integration point.

Parameters

gp	Integration point where newly created status will be stored.

Returns: Reference to new status.

Reimplemented from oofem::Material.

Definition at line 84 of file newtonianfluid.C.

◆ give()

double oofem::NewtonianFluidMaterial::give	(	int	aProperty,
		GaussPoint *	gp ) const

overridevirtual

Returns the value of material property 'aProperty'. Property must be identified by unique int id. Integration point also passed to allow for materials with spatially varying properties

Parameters

aProperty	ID of property requested.
gp	Integration point,

Returns: Property value.

◆ giveClassName()

const char * oofem::NewtonianFluidMaterial::giveClassName ( ) const

inlineoverridevirtual

Returns: Class name of the receiver.

◆ giveEffectiveViscosity()

double oofem::NewtonianFluidMaterial::giveEffectiveViscosity	(	GaussPoint *	gp,
		TimeStep *	tStep ) const

overridevirtual

Gives the effective viscosity for the given integration point.

Parameters

gp	Gauss point of interest.
tStep	Time step.

Returns: The effective viscosity in the point.

◆ giveInputRecord()

void oofem::NewtonianFluidMaterial::giveInputRecord ( DynamicInputRecord & input )

overridevirtual

Setups the input record string of receiver.

Parameters

input Dynamic input record to be filled by receiver.

References _IFT_NewtonianFluidMaterial_mu, oofem::DynamicInputRecord::setField(), and viscosity.

◆ giveInputRecordName()

const char * oofem::NewtonianFluidMaterial::giveInputRecordName ( ) const

inlineoverridevirtual

Returns: Input record name of the receiver.

Implements oofem::FEMComponent.

References _IFT_NewtonianFluidMaterial_Name.

◆ initializeFrom()

void oofem::NewtonianFluidMaterial::initializeFrom ( InputRecord & ir )

overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization
