Member Function Documentation

◆ checkConsistency()

int oofem::TR1_2D_PFEM::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.

◆ giveDofManDofIDMask()

void oofem::TR1_2D_PFEM::giveDofManDofIDMask	(	int	inode,

See also: InterfaceType

Returns: Requested interface if implemented, otherwise NULL.

Implements oofem::PFEMElement2d.

◆ giveInternalStateAtNode()

int oofem::TR1_2D_PFEM::giveInternalStateAtNode	(	FloatArray &	answer,
		InternalStateType	type,
		InternalStateMode	mode,
		int	node,
		TimeStep *	tStep )

overridevirtual

Returns internal state variable (like stress,strain) at node of element in Reduced form, the way how is obtained is dependent on InternalValueType. The value may be local, or smoothed using some recovery technique. Returns zero if element is unable to respond to request.

Parameters

answer	Contains result, zero sized if not supported.
type	Determines the internal variable requested (physical meaning).
mode	Determines the mode of variable (recovered, local, ...).
node	Node number, for which variable is required.
tStep	Time step.

Returns: Nonzero if o.k, zero otherwise.
