Detailed Description

template<unsigned int VDimension = 3>
class itk::fem::FEMObject< VDimension >

Implements N-dimensional Finite element (FE) models including elements, materials, and loads.

Overview: FEMObject was created to provide an object in ITK that specifies the entire FE model. This model can then be passed to the itk::fem::Solver to generate a solution for the model. The design for this class was modelled after the itk::Mesh structure. Presently, no direct I/O support for the FEMObject exists. This must be done using the FEMSpatialObject. The FEMObject simply serves as a storage container for the FE model.

The FEMObject stores the FE problem using Vector Containers for 1) Load 2) Material 3) Element 4) Node

Usage: The user can set the Vector Containers that define the Load, Material, Element, and Nodes using the AddNext<Object> and Insert<Object> methods. The user can also get the entire VectorContainer using the Get<Object>Container(). For convience methods are also provided to get any item in the vector containers based on their index (Get<Object>) or their global number (Get<Object>WithGlobalNumber). This class does not know anything about the types of elements, materials, elements, or nodes. The problem presently can only be 2D or 3D.
