Detailed Description

template<typename Space_>
class FEAT::Space::DofMappingBase< Space_ >

Mapping from mesh cells to Dof that have support on them.

This class acts as a base-class and interface documentation for Finite Element Dof mapping implementations.

In FEAT, every FE basis function is associated with a mesh entity of a certain shape dimension, i.e. vertices, facets or cells. The DofMapping maps a mesh cell (meaning only the highest-dimensional entities of a mesh) to a set of basis functions with nonempty support on the closure of the cell. It does, however, not contain any information about which entities of that cell are associated with which basis function. This is done by the DofAssignment.
