Detailed Description

Virtual element load base class.

This load class defines an external load that acts on elements in a system. The vector with pointers to elements defines, on which elements the load acts. The derived load classes should provide members, that allow the Element's class Fe() member function to uniquely transform the load into nodal loads. No special requirements are enforced on those members.

Ultimately, when assembling the right hand side of the master equation (master force vector) the Element's Fe() member funtion is called with the pointer to the LoadElement class that is prescribed on that element. Fe() function shuld dynamically cast this pointer to specific load class, which it can handle and return the element's force vector.

Member Function Documentation

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

Virtual function to access the class ID

Implements itk::fem::FEMLightObject.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadEdge, itk::fem::LoadGravConst, itk::fem::LoadLandmark, itk::fem::LoadPoint, and itk::fem::LoadTest< TClass >.

Definition at line 43 of file itkFEMLoadElementBase.h.

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

Create a new object from the existing one

Implements itk::fem::FEMLightObject.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadEdge, itk::fem::LoadGravConst, itk::fem::LoadLandmark, itk::fem::LoadPoint, and itk::fem::LoadTest< TClass >.

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.

virtual Solution::ConstPointer itk::fem::Load::GetSolution ( ) [inline, virtual, inherited]

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object.

Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.

Parameters:

ptr

Pointer to the object of Solution class.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, and itk::fem::LoadLandmark.

Definition at line 57 of file itkFEMLoadBase.h.

static Self::Pointer itk::fem::LoadElement::New ( void ) [inline, static]

Object creation in an itk compatible way

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadEdge, itk::fem::LoadGravConst, itk::fem::LoadLandmark, itk::fem::LoadPoint, and itk::fem::LoadTest< TClass >.

Definition at line 43 of file itkFEMLoadElementBase.h.

virtual void itk::fem::LoadElement::Read	(	std::istream &	f,
		void *	info
	)			`[virtual]`

pointers to element objects on which the load acts

Reimplemented from itk::fem::FEMLightObject.

Reimplemented in itk::fem::LoadEdge, itk::fem::LoadGravConst, itk::fem::LoadLandmark, and itk::fem::LoadTest< TClass >.

Referenced by itk::fem::LoadTest< TClass >::Read().

virtual void itk::fem::Load::SetSolution ( Solution::ConstPointer ) [inline, virtual, inherited]

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object.

Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.

Parameters:

ptr

Pointer to the object of Solution class.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, and itk::fem::LoadLandmark.

Definition at line 56 of file itkFEMLoadBase.h.

static void itk::fem::FEMLightObject::SkipWhiteSpace ( std::istream & f ) [static, inherited]

Helper function that skips all the whitespace and comments in an input stream.

void itk::fem::LoadElement::Write ( std::ostream & f ) const [virtual]

Write an object to the output stream. Call this member to write the data members in the current object to the output stream. Here we also need to know which derived class we actually are, so that we can write the class name. The class name is obtained by calling the virtual ClassID() member function and passing the result to the FEMObjectFactory.

Implementations of Write member funtion in derived classes should first call the parent's implementation of Write and finaly write whatever they need.

Reimplemented from itk::fem::FEMLightObject.

Reimplemented in itk::fem::LoadEdge, itk::fem::LoadGravConst, itk::fem::LoadLandmark, and itk::fem::LoadTest< TClass >.

Referenced by itk::fem::LoadTest< TClass >::Write().

int itk::fem::FEMLightObject::GN [inherited]

Global number of an object (ID of an object) In general the ID's are required to be unique only within a specific type of derived classes (Elements, Nodes, ...) If the GN is not required, it can be ignored. (normally you need the GN when writing or reading objects to/from stream.
