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.

IRResultType oofem::GravityPressure::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.
