Detailed Description

Class representing user defined temperature field.

User input is function expression, as a function of global x,y and z coordinates and time t.

The load time function is not used here, the function provided is supposed to be function of time and coordinates.

Uses Parser class to parse given expression. Slow but useful. Temperature load as body load is typically attribute of domain and is attribute of one or more elements.

Member Function Documentation

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

virtual

Computes components values of temperature field at given point (coordinates given in Global c.s.).

taking into account corresponding load time function value respecting load response mode.

Parameters

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

IRResultType oofem::UserDefinedTemperatureField::initializeFrom ( InputRecord * ir )

virtual

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.
