Member Function Documentation

int oofem::PFEMElement2d::checkConsistency ( )

virtual

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.

virtual void oofem::PFEMElement2d::giveDofManDofIDMask	(	int	inode,
		IntArray &	answer
	)		const

pure virtual

Returns dofmanager dof mask for node.

This mask defines the dofs which are used by element in node. Mask influences the code number ordering for particular node. Code numbers are ordered according to node order and dofs belonging to particular node are ordered according to this mask. If element requests dofs using node mask which are not in node then error is generated. This masking allows node to be shared by different elements with different dofs in same node. Elements local code numbers are extracted from node using this mask. Must be defined by particular element.

Parameters

inode	Mask is computed for local dofmanager with inode number.
answer	Mask for node.

virtual void oofem::PFEMElement2d::giveElementDofIDMask ( IntArray & answer ) const

pure virtual

Returns element dof mask for node.

This mask defines the dof ordering of the element interpolation. Default implementation for most elements, with noteable exceptions such as XFEM and some types of shell elements.

Parameters

ut	Equation DOFs belong to.
answer	DOF mask for receiver.

		InternalStateType	type,
		InternalStateMode	mode,
		int	node,
		TimeStep *	tStep
	)

pure virtual

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.
