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 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.

vnl_matrix<Float> itk::fem::LoadEdge::m_Force

protected

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.
