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.

Member Function Documentation

virtual void itk::fem::LoadEdge::ApplyLoad ( Element::ConstPointer  element,
Element::VectorType Fe 
) [virtual]

Apply the load to the specified element

Reimplemented from itk::fem::LoadElement.

virtual::itk::LightObject::Pointer itk::fem::LoadEdge::CreateAnother ( void  ) const [virtual]

CreateAnother method will clone the existing instance of this type, including its internal member variables.

Reimplemented from itk::fem::LoadElement.

int itk::fem::LoadEdge::GetEdge ( ) const

Get the edge number on which the force is being applied

vnl_matrix<itk::fem::Element::Float>& itk::fem::LoadEdge::GetForce ( )

Get the edge force values

const vnl_matrix<itk::fem::Element::Float>& itk::fem::LoadEdge::GetForce ( ) const

Get the edge force values

virtual const char* itk::fem::LoadEdge::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::fem::LoadElement.

static Pointer itk::fem::LoadEdge::New ( ) [static]

New macro for creation of through the object factory.

Reimplemented from itk::fem::LoadElement.

virtual void itk::fem::LoadEdge::PrintSelf ( std::ostream &  os,
Indent  indent 
) const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::fem::LoadElement.

void itk::fem::LoadEdge::SetEdge ( int  edge)

Set the edge number on which the force is being applied

void itk::fem::LoadEdge::SetForce ( const vnl_matrix< itk::fem::Element::Float force)

Set the edge force values


Member Data Documentation

int itk::fem::LoadEdge::m_Edge [protected]

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 91 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.
