Detailed Description

All classes related to shape functions and to access to shape functions. This concerns the actual values of finite elements. For the numbering of degrees of freedom refer to the module on Degrees of Freedom.

The classes and functions of this module fall into several sub-groups that are discussed in their respective sub-modules listed above. In addition, the FETools class provides functions that provide information on finite elements, transformations between elements, etc.

In the grand scheme of things, the pieces of this module interact with a variety of other parts of the library:
