Detailed Description

A namespace for "views" on a FEValues, FEFaceValues, or FESubfaceValues object. A view represents only a certain part of the whole: whereas the FEValues object represents all values, gradients, or second derivatives of all components of a vector-valued element, views restrict the attention to only a single component or a subset of components.

There are classes that present views for single scalar components as well as vector components consisting of dim elements.

See the description of the Handling vector valued problems module for examples how to use the features of this namespace.
