Type characterizing the dependence of the internal lenght on variable of the state Note that the assigned numbers to enum values have to correspond to values used in initializeFrom to resolve internalLenghtDependence. If not, the consistency between initializeFrom and giveInputRecord methods is lost.

Computes the stiffness matrix for giveRealStressVector of receiver in given integration point, respecting its history. The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters

answer	Contains result.
mode	Material response mode.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).

Tests if material supports material mode.

Parameters

mode	Required material mode.

initializeFrom()

void oofem::IsotropicGradientDamageMaterial::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.
