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.

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

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.
