Detailed Description

This class implements a gravity-like load, or internal source (heat etc.) for transport problems.

The inherited attribute 'componentArray' contains the components of an loading prescribed per unit volume.

Its task is to return the body force $ \rho a $

virtual bcGeomType oofem::DeadWeight::giveBCGeoType ( ) const

Returns receiver's load geometry type.

virtual bcValType oofem::DeadWeight::giveBCValType ( ) const

Returns receiver load type.

It distinguish particular boundary conditions according to their "physical" meaning (like StructuralTemperatureLoadLT, StructuralLoadLT). Derived classes should always overload, default implementation returns UnknownLT value. See cltypes.h file for details.
