Computes characteristic matrix of receiver in given integration point.

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).

Computes the characteristic value 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.

virtual

Returns the flux for the field and its gradient.

Todo:: { Should the field variable just be a scalar? This might change when we rethink the coupled-fields approach. Now its either just [temperature], or [temperature, concentration] so to cover both cases there is a floatarray. }

Parameters

answer	The flux.
gp	Gauss point.
grad	Gradient of the primary field, usually the main input.
field	The value of the field itself.
tStep	Active time step.

IRResultType oofem::LatticeTransportMaterial::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.
