int oofem::IntMatBilinearCZ::checkConsistency ( )
protectedvirtual

Allows programmer to test some internal data, before computation begins.

For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns
Nonzero if receiver is consistent.

Tells if the model has implemented analytical tangent stiffness.

If not, the tangent must be computed numerically.

IRResultType oofem::IntMatBilinearCZ::initializeFrom ( InputRecord ir)
virtual

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.
