Detailed Description
A generic load that can be applied to an edge of the element.
Can also be used to apply natural (Neumann) boundary condition on the edge of the element. In this case m_Edge defines the edge or surfance of the element on which the BC exists and matrix m_Force holds the actual prescribed values of the BC.

| virtual int itk::fem::LoadEdge::ClassID | ( | ) | const [inline, virtual] |
Virtual function to access the class ID
Reimplemented from itk::fem::LoadElement.
Definition at line 38 of file itkFEMLoadEdge.h.
| virtual Baseclass::Pointer itk::fem::LoadEdge::Clone | ( | ) | const [virtual] |
Create a new object from the existing one
Reimplemented from itk::fem::LoadElement.
| 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.

Object creation in an itk compatible way

| virtual void itk::fem::LoadEdge::Read | ( | std::istream & | f, | |
| void * | info | |||
| ) | [virtual] |
Read a Load object from input stream. We need arrays of elements and nodes to do that.
Reimplemented from itk::fem::LoadElement.
| 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.

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.

Local number of the edge (face) of the element on which the load acts. Check the corresponding element class for more info on edge numbering.
Definition at line 57 of file itkFEMLoadEdge.h.
An edge force matrix. This matrix specifies nodal forces on all nodes within the edge or face on which the load acts. Each nodal force is decomposed into several components (check the documentation inside the element class). In case of 2D elements this components are normal (1st component) and tangential (2nd component) force acting on the edge of the element. A positive normal load acts in a direction INTO the element. A positive tangential load acts in an ANTICLOCKWISE direction with respect to the loaded elemenet. Each nodal force is stored in a column of the matrix. The number of columns in the Force matrix must correspond to the number of nodes that define the edge (face...). The force is interpolated over the entire edge (face) by using the shape functions of the element. Again check the documentation of the element class to which the force is applied.
