Detailed Description

Abstract base class representing a point load (force, momentum, ...) that acts directly on or inside of some finite element.

Methods for returning values of load components and returning the position of load are provided.

Note: This class is not restricted to structural problems. For example, in thermal analysis, a point load load could be a point heat source.

Constructor & Destructor Documentation

◆ PointLoad()

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

inline

Constructor. Creates Boundary Load object with given number, belonging to given domain.

Parameters

n	Load number.
d	Domain to which new object will belongs.

◆ computeValueAt()

void oofem::PointLoad::computeValueAt	(	FloatArray &	answer,
		TimeStep *	tStep,
		const FloatArray &	coords,
		ValueModeType	mode )

overridevirtual

Computes components values of load at given point - global coordinates (coordinates given).

Parameters

answer	Component values at given point and time.
tStep	Time step representing time.
coords	Global (or local) problem coordinates, which are used to evaluate components values.
mode	Determines response mode.

Implements oofem::Load.

◆ giveBCGeoType()

bcGeomType oofem::PointLoad::giveBCGeoType ( ) const

inlineoverridevirtual

Returns receiver's load geometry type.

Returns: BodyLoadBGT.

Reimplemented from oofem::BodyLoad.

Definition at line 94 of file pointload.h.

◆ giveClassName()

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

inlineoverridevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

Definition at line 95 of file pointload.h.

◆ giveCoordinates()

const FloatArray & oofem::PointLoad::giveCoordinates ( ) const

inline

Gives coordinates of the receiver

Definition at line 85 of file pointload.h.

References coords.

Referenced by oofem::StructuralElement::computeLoadVector(), and oofem::StructuralElement::computePointLoadVectorAt().

◆ giveCoordSystMode()

CoordSystType oofem::PointLoad::giveCoordSystMode ( )

◆ giveInputRecord()

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

overridevirtual

Setups the input record string of receiver.

Parameters

input Dynamic input record to be filled by receiver.

◆ giveInputRecordName()

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

inlineoverridevirtual

Returns: Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 96 of file pointload.h.

References _IFT_PointLoad_Name.

◆ giveType()

bcType oofem::PointLoad::giveType ( ) const

inlineoverridevirtual

Returns: Type of boundary condition. It allows to distinguish BC according its mathematical meaning, ie. like Dirichlet, Neumann, or Newton type.

Reimplemented from oofem::GeneralBoundaryCondition.

Definition at line 93 of file pointload.h.

References lType.

◆ initializeFrom()

void oofem::PointLoad::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
