Detailed Description

This class implements a gravity-like load. The attribute 'componentArray' contains the components of an acceleration 'a', expected (but not required) to be downwards vertical. Task: returning the body force rho*a acting on a given element.

Member Function Documentation

◆ computeValueAt()

void oofem::GravityPressure::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::GravityPressure::giveBCGeoType ( ) const

inlineoverridevirtual

Returns receiver's load geometry type.

Returns: BodyLoadBGT.

Reimplemented from oofem::BodyLoad.

Definition at line 71 of file gravitypressure.h.

References oofem::GravityPressureBGT.

◆ giveClassName()

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

inlineoverridevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

Definition at line 76 of file gravitypressure.h.

◆ giveInputRecordName()

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

inlineoverridevirtual

Returns: Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 77 of file gravitypressure.h.

References _IFT_GravityPressure_Name.

◆ initializeFrom()

void oofem::GravityPressure::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.
