Detailed Description

Abstract class Dof represents Degree Of Freedom in finite element mesh.

DOFs are possessed by DofManagers (i.e, nodes, sides or whatever) and one DOF belongs to only one DofManager. Dof maintain its related equation or prescribed equation number. This equation number is usually assigned by EngngModel, however, several numbering schemes can exists (see giveEquationNumber and similar services).

It maintains also its physical meaning and reference to related DofManager (reference to DofManager which possess particular DOF). To describe physical meaning of particular Dof, special enum type DofId has been introduced (see cltypes.h). This type is more descriptive than UnknownType, which determines physical meaning for unknowns generally (displacement or temperature). DofId type must distinguish between dofs having displacement unknown, but in different directions, because only some of these may be required by elements.

Dof can be subjected to boundary (BC) or initial (IC) condition. Method for obtaining corresponding DOF unknown value is provided. If no IC condition has been given, zero value IC is assumed otherwise when needed.

Dof class generally supports changes of static system during computation. This feature generally leads to equation renumbering. Then because equation number associated to dof may change, it may become extremely complicated to ask EngngModel for unknown from previous time step (because equation number may have been changed). To overcome this problem, derived class will implement so called unknown dictionary, which is updated after finishing each time step and where unknowns for particular dof are stored. Dof then uses this dictionary for requests for unknowns instead of asking EngngModel for unknowns. Unknowns in dof dictionary are updated by EngngModel automatically (if EngngModel supports changes of static system) after finishing time step.

Member Function Documentation

virtual int oofem::Dof::__giveEquationNumber ( ) const

pure virtual

Returns equation number of receiver, usually assigned by emodel.

If Dof has active BC, returned equation number is zero. After initializing Dof by calling constructor, Dof has no equation number assigned. When firstly invoked, this function asks EngngModel object for next equation prescribed equation number (this will increase also total number of equation at EngngModel level). Note: By asking nodal code numbers or element code numbers when initializing code numbers in EngngMode, designer should alter equation numbering strategy.

Returns: Equation number of DOF.

Implemented in oofem::MasterDof, oofem::SlaveDof, oofem::SimpleSlaveDof, and oofem::ActiveDof.

virtual int oofem::Dof::__givePrescribedEquationNumber ( )

pure virtual

Returns prescribed equation number of receiver.

If Dof has inactive BC, returned prescribed equation number is zero. If Dof has active BC, then the corresponding prescribed equation number is returned. is zero. After initializing Dof by calling constructor, Dof has no prescribed equation number assigned. When firstly invoked, this function asks EngngModel object for next equation or prescribed equation number (this will increase also total number of equation at EngngModel level). Note: By asking nodal code numbers or element code numbers when initializing code numbers in EngngMode, designer should alter equation numbering strategy.

Returns: Prescribed equation number.

virtual bool oofem::Dof::isPrimaryDof ( )

Tests if receiver is primary DOF.

Returns: True if receiver is primary DOF, false otherwise (default).

virtual int oofem::Dof::packUnknowns	(	DataStream &	buff,
		ValueModeType	mode,
		TimeStep *	tStep
	)

inlinevirtual

Packs specific DOF Manager's dofs unknowns into communication buffer.

If dof is slave, then no packing is done, this is maintained by master. This requires master be available at same partition as slave.

Parameters

buff	Communication buffer to pack data.
mode	Mode of unknown (e.g, total value, velocity or acceleration of unknown).
tStep	Time step when unknown requested. See documentation of particular EngngModel class for valid tStep values (most implementations can return only values for current and possibly for previous time step).

Returns: Nonzero if successful.

virtual int oofem::Dof::unpackAndUpdateUnknown	(	DataStream &	buff,
		ValueModeType	mode,
		TimeStep *	tStep
	)

inlinevirtual

Unpacks DOF unknown from communication buffer and updates unknown if necessary.

Unknown is always updated using EngngModel::updateUnknownComponent, if DOFManager to which receiver belongs has DofManager_shared dofManagerParallelMode type. Unknown is unpacked and stored in unknowns dictionary, if DOFManager to which receiver belongs has DofManager_remote dofManagerParallelMode type. There is no reason for invoking this service if DOFManager has DofManager_local mode. If do is slave, then no unpacking and updating is done. This is left on master, which must be available on same partition.

Parameters

buff	Buffer containing packed message.
mode	Mode of unknown (e.g, total value, velocity or acceleration of unknown).
tStep	Time step when unknown requested. See documentation of particular EngngModel class for valid tStep values (most implementations can return only values for current and possibly for previous time step).

Returns: Nonzero if successful.

virtual void oofem::Dof::updateLocalNumbering ( EntityRenumberingFunctor & f )

inlinevirtual

Local renumbering support.

For some tasks (parallel load balancing, for example) it is necessary to renumber the entities. The various FEM components (such as nodes or elements) typically contain links to other entities in terms of their local numbers, etc. This service allows to update these relations to reflect updated numbering. The renumbering function is passed, which is supposed to return an updated number of specified entity type based on old number.

Parameters

f	Function that converts old to new equation number.

virtual void oofem::Dof::updateUnknownsDictionary	(	TimeStep *	tStep,
		ValueModeType	mode,
		double	dofValue
	)

inlinevirtual

Abstract function, allowing Dof to store its unknowns in its own private dictionary.

Dof then uses this dictionary instead of forwarding the requests to EngngModel (with equationNUmber as parameter). If EngngModel does not support changes of static system (see EngngModel::requiresUnknownsDictionaryUpdate method), the dof forwards the requests for its unknowns to EngngModel, where unknowns are naturally kept. This is possible, because dof equation number is same during whole solution. But when changes of static system are allowed, several problem arise. For example by solving simple incremental static with allowed static changes, the incremental displacement vector of structure can not be added to total displacement vector of structure, because equation numbers may have changed, and one can not simply add these vector to obtain new total displacement vector, because incompatible displacement will be added. To solve this problem, unknown dictionary at dof level has been assumed. Dof then keeps its unknowns in its own private dictionary. After computing increment of solution, engngModel updates for each dof its unknowns in its dictionary (using updateUnknownsDictionary function). For aforementioned example engngModel updates incremental values but also total value by asking dof for previous total value (dof will use its dictionary, does not asks back EngngModel) adds corresponding increment and updates total value in dictionary. In fact on EngngModel level only incremental solution is stored, but total values are always stored in dofs dictionaries. Implementation is not provided, only interface declared. Children must implement this method.

Parameters

tStep	Time step when unknowns are updated. In current version it is unused parameter. It is EngngModel responsibility to update values, and values stored in dictionary are always related to timeStep when they were lastly updated.
mode	Mode of stored unknown.
dofValue	Value of unknown. Old value will generally be lost.
