Detailed Description

Abstract base class for all finite elements.

Derived clases should be base clases for specific analysis type (for example base class for structural analysis, thermal analysis or magnetostatics one). These derived classes then declare analysis-specific part of interface and they provide default implementation for these methods. This abstract class declares (and possibly implements) general data and methods common to all element types. General methods for obtaining characteristic vectors, matrices and values are introduced and should be used instead of calling directly specific member functions (these must be overloaded by derived analysis-specific clases in order to invoke proper method acording to type of component requested). In general, element class memeber functions are called in following cases:

When Engineering model assembles governing equation(s) from element's contributions. Typically when assembles some characteristic matrix of analyzed structure (method assemble), asks each element for its code numbers and for corresponding characteristic matrix, vector or value. This will typically uses above mentioned general method for obtaining characteristic matrices, vectors and values from elements.
When Engineering model has some characteristic matrix stored in sparse form, then is necessary to build internal profile of such sparse matrix. Engineering model then typically calls buildInternalStructure member function of sparse matrix. This method then requests element code numbers from elements and builds its internal profile. This could look strange, because class sparse matrix should know "something about eleemnts", but only sparse matrix knows, how to build its internal structure (this may require one or more loops over elements code number).
When element computes its contribution, then it comunicates with its cross-section (and cross section with corresponding material). For some cross-section or matrial models some further communication between these classes and element may be necessary (for example in cases of layered cross section model strains in each layer has to be evaluated from "integrated" strains (integrated means element-like strains including curvatures in case of beams and plates) by element, in cases of non local material and many other examples can be found).

There are some general rules, that programmer must take into account.

Element stores the numbers of its dofnamagers in dofManArray. These include nodes, element sides and internal DOFs that are not condensed at element level. Their order and meaning are determined by element definition. Local ordering of dofs for particular element is determined by local numbering of dofnamagers and their corresponding dofs. DOFS necessary for particular node/side is specified using node/side dof mask. Local DOF ordering must be taken into account when assembling various local characteristic vectors and matrices.

Member Function Documentation

void Element::giveLocationArray	(	IntArray &	locationArray,
		EquationID	ut,
		const UnknownNumberingScheme &	s
	)			const `[virtual]`

Returns the location array (array of code numbers) of receiver for given numbering scheme.

Results are cached at receiver for default scheme in locationArray attribute. The UnknownType parameter allows to distinguis between several possible governing equations, that can be numbered separately. The default implementation assumes that location array will be assembled only for one UnknownType value, and this array is cached on element level.

Reimplemented in PlaneStress2dXfem.

void Element::invalidateLocationArray ( )

Invalidates location array in receiver.

Each element stores its copy of location array(s), in order to avoid time consuming assembly of code numbers every time when requested. Some enginnering models may support dynamic changes of static system (generally of boundary conditions during analysis), then these models use this function to invalidate location array after finishing time step, to enforce elements to update they code numbers, which may change. Changes of static system will lead to different number of equations, which requires special attention (for example internal structure of sparse matrices must be reinitialized and characteristic vectors and matrices has to be newly assembled).

But generally all enginnering models should be able return supported unknowns at current and previous time step. Consult reference manual for particular engineering model.

virtual void Element::updateBeforeNonlocalAverage ( TimeStep * atTime ) [inline, virtual]

Updates internal element state (in all integration points of receiver) before nonlocal averaging takes place.

Used by so nonlocal materials, because their response in particular point depends not only on state in this point, but depends also on state in point's neighbourhood. Nonlocal quatity is computed as nonlocal average of local quantities. Therefore, before updating integration point state depending on nonlocal quantity (or quantities), local quantities in all integration points must be updated in advance. This function should be overloaded by derived analysis-specific class, which updates state in all receiver's integration points (using updateBeforeNonlocalAverage member function deklared at corresponding analysis specific material base class) depending on driving variable (for example - strain vector in case of structural-analysis elements).

int Element::packUnknowns	(	CommunicationBuffer &	buff,
		TimeStep *	stepN
	)

Pack all necessary data of element (according to its parallel_mode) integration points into given communication buffer.

The corresponding cross section service is invoked, which in turn should invoke material model service for particular integration point. The nature of packed data is material model dependent. Typically, for material of "local" response (response depeneds only on integration point local state) no data are exchanged. For "nonlocal" constitutive models the send/receive of local values which undergo averaging is performed between local and corressponding remote elements.

Parameters:

	buff	communication buffer
	stepN	solution step.
