Detailed Description

This class implements an enhanced piecewise linear function with periodicity. and possibility to add another arbitrary time function.

The function is defined by 'numberOfPoints' points. 'dates' and 'values' store respectively the abscissas (t) and the values (f(t)) of the points The values are repeated after 'period'. 'AddTF' parameter specifies number of function to add.

◆ evaluateVelocityAtTime()

double oofem::PeriodicPiecewiseLinFunction::evaluateVelocityAtTime ( double t )

overridevirtual

Returns the first time derivative of the function at given time.

Parameters

t Time.

Returns: \( f'(t) \).

◆ giveClassName()

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

inlineoverridevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

Definition at line 80 of file periodicpiecewiselinfunction.h.

◆ giveInputRecord()

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

overridevirtual

Setups the input record string of receiver.

Parameters

input Dynamic input record to be filled by receiver.

Reimplemented from oofem::FEMComponent.

◆ giveInputRecordName()

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

inlineoverridevirtual

Returns: Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 81 of file periodicpiecewiselinfunction.h.

References _IFT_PeriodicPiecewiseLinFunction_Name.

◆ initializeFrom()

void oofem::PeriodicPiecewiseLinFunction::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.
