Detailed Description

template<int dim, int spacedim = dim, typename number = double>
class MeshWorker::DoFInfo< dim, spacedim, number >

A class containing information on geometry and degrees of freedom of a mesh object.

The information in these objects is usually used by one of the Assembler classes. It is also the kind of information which is needed in mesh based matrices (often referred to as matrix free methods).

In addition to the information on degrees of freedom stored in this class, it also provides the local computation space for the worker object operating on it in LocalResults. This base class will automatically be reinitialized on each cell, but initial setup is up to the user and should be done when initialize() for this class is called.

This class operates in two different modes, corresponding to the data models discussed in the Assembler namespace documentation.

The choice of the local data model is triggered by the vector BlockInfo::local_renumbering, which in turn is usually filled by BlockInfo::initialize_local(). If this function has been used, or the vector has been changed from zero-length, then local dof indices stored in this object will automatically be renumbered to reflect local block structure. This means, the first entries in indices will refer to the first block of the system, then comes the second block and so on.

The BlockInfo object is stored as a pointer. Therefore, if the block structure changes, for instance because of mesh refinement, the DoFInfo class will automatically use the new structures.
