Declared protected variable DislocationSource::d of type Dislocation.
This variable represents the dislocation segment that forms the Frank-
DislocationSource contructors modified
The DislocationSource contructors have been modified to create the
dislocation that is now part of the class.
DislocationSource constructor contains calls to Defect constructor
Redundant set position call removed.
Virtual function defining the stressField is included.
'virtual outside class declaration' error resolved.
Defined function DislocationSource::checkStress to determine direction
of motion of dislocation
The dislocation within the DislocationSource is responsible for the
emission of dipoles. The motion of this dislocation thus decides if the
Frank-Read loop has opened up sufficiently to emit a dipole. The
direction of the motion is returned by this function.
