Member Function Documentation

◆ checkConsistency()

int oofem::PFEMElement::checkConsistency ( void )

overridevirtual

Performs consistency check. This method is called at startup for all elements in particular domain. This method is intended to check data compatibility. Particular element types should test if compatible material and crossSection both with required capabilities are specified. Derived classes should provide their own analysis specific tests. Some printed input if incompatibility is found should be provided (error or warning member functions). Method can be also used to initialize some variables, since this is invoked after all domain components are instanciated.

Returns: Zero value if check fail, otherwise nonzero.
