		Node::ConstPointer	n2_,
		Material::ConstPointer	mat_
	)

Construct an element by specifying two nodes and material

virtual int itk::fem::Element2DC1Beam::ClassID ( ) const [inline, virtual]

Virtual function to access the class ID

Implements itk::fem::FEMLightObject.

Definition at line 38 of file itkFEMElement2DC1Beam.h.

virtual Baseclass::Pointer itk::fem::Element2DC1Beam::Clone ( ) const [virtual]

Create a new object from the existing one

Implements itk::fem::FEMLightObject.

static FEMLightObject::Pointer itk::fem::FEMLightObject::CreateFromStream	(	std::istream &	f,
		void *	info
	)			`[static, inherited]`

Read object of any derived type from stream.

This static function creates an object of a class, which is derived from FEMLightObject. The class of object is first determined from the stream, then the object of that class is constructed using the FEMObjectFactory. Finally the data for this object is read from the stream, by calling the Read() member function.

DegreeOfFreedomIDType itk::fem::Element::GetDegreeOfFreedom ( unsigned int local_dof ) const [inline, inherited]

Convenient way to access IDs of degrees of freedom that are stored in node objects.

Parameters:

local_dof

Local number of degree of freedom within an element.

Definition at line 394 of file itkFEMElementBase.h.

References itk::fem::Element::GetNode(), and itk::fem::Element::InvalidDegreeOfFreedomID.

virtual Float itk::fem::Element::GetElementDeformationEnergy ( MatrixType & LocalSolution ) const [virtual, inherited]

Compute the physical energy, U, of the deformation (e.g. stress / strain ).

T U = u Ke u

The matrix LocalSolution contains the solution to use in the energy computation. Usually, this is the solution at the nodes.

virtual VectorType itk::fem::Element::GetGlobalFromLocalCoordinates ( const VectorType & pt ) const [virtual, inherited]

Transforms the given local element coordinates into global.

Parameters:

pt

Point in local element coordinates.

virtual void itk::fem::Element::GetIntegrationPointAndWeight	(	unsigned int	i,
		VectorType &	pt,
		Float &	w,
		unsigned int	order = `0`
	)			const `[pure virtual, inherited]`

Computes the vector representing the i-th integration point in local element coordinates for a Gauss-Legendre numerical integration over the element domain. It also computes the weight at this integration point.

Optionally you can also specify the order of integration. If order is not specified, it defaults to 0, which means that the derived element should use the optimal integration order specific for that element.

Note:: This function must be implemented in derived element classes, and is expected to provide valid integration points for up to gaussMaxOrder-th order of integration.

Parameters:

	i	Integration point number 0<=i<GetNumberOfIntegrationPoints()
	pt	Reference to object of class VectorType that will hold the integration point.
	w	Reference to Float variable that will hold the weight.
	order	Order of integration.

See also:: GetNumberOfIntegrationPoints()

virtual void itk::fem::Element2DC1Beam::GetIntegrationPointAndWeight	(	unsigned int	i,

	)			const `[virtual]`

virtual void itk::fem::Element::GetLandmarkContributionMatrix	(	float	eta,

	)			const `[virtual, inherited]`

Compute and return landmark contribution to element stiffness matrix (Le) in global coordinate system.

b T int (1/eta)^2 N(x) N(x) dx a

where (eta ) is the landmark weight. Implementation is similar to GetMassMatrix.

virtual void itk::fem::Element::GetLoadVector	(	LoadPointer	l,
		VectorType &	Fe
	)			const `[pure virtual, inherited]`

Compute and return the element load vector for a given external load. The class of load object determines the type of load acting on the elemnent. Basically this is the contribution of this element on the right side of the master matrix equation, due to the specified load. Returned vector includes only nodal forces that correspond to the given Load object.

Visitor design pattern is used in the loads implementation. This function only selects and calls the proper function based on the given class of load object. The code that performs the actual conversion to the corresponding nodal loads is defined elswhere.

Note:: Each derived class must implement its own version of this function. This is automated by calling the LOAD_FUNCTION() macro within the class declaration (in the public: block).

For example on how to define specific element load, see funtion LoadImplementationPoint_Bar2D.

Note:: : Before a load can be applied to an element, the function that implements a load must be registered with the VisitorDispactcher class.

Parameters:

	l	Pointer to a load object.
	Fe	Reference to vector object that will store nodal forces.

See also:: VisitorDispatcher

virtual bool itk::fem::Element2DC1Beam::GetLocalFromGlobalCoordinates	(	const VectorType &	,

Parameters:

	globalPt	Reference to vector containing a point in global (world) coordinates.

Compute and return element mass matrix (Me) in global coordinate system.

b T int N(x) (rho c) N(x) dx a

where (rho c) is constant (element density), which is here assumed to be equal to one. If this is not the case, this function must be overriden in a derived class. Implementation is similar to GetStiffnessMatrix.

Compute and return element stiffnes matrix (Ke) in global coordinate system. The base class provides a general implementation which only computes

b T int B(x) D B(x) dx a

using the Gaussian numeric integration method. The function calls GetIntegrationPointAndWeight() / GetNumberOfIntegrationPoints() to obtain the integration points. It also calls the GetStrainDisplacementMatrix() and GetMaterialMatrix() member functions.

Note:: This is a very generic implementation of the stiffness matrix that is suitable for any problem/element definition. A specifc element may override this implementation with its own simple one.
