◆ initializeFrom()

void oofem::Crack::initializeFrom ( InputRecord & ir )

overridevirtual

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. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization

◆ mCohesiveZoneGaussPoints

std :: vector< GaussPoint * > oofem::Crack::mCohesiveZoneGaussPoints

protected

Array of pointers to the Gauss points related to the cohesive zone. The array is used for data extraction and visualization only. The reason for keeping an array of pointers here is as follows: the cohesive zone Gauss points are created in the XFEMElementInterface, that (of course) only keeps track of GPs in that element. However, for visualization it is very valuable to be able to plot cohesive zone data (e.g. damage or crack opening) vs the arc length coordinate of the crack. This must be accomplished at the level of the EnrichmentItem, because here we know about the geometry of the crack.
