Detailed Description

The DofObject defines an abstract base class for objects that have degrees of freedom associated with them.

Examples of such objects are the Node and Elem classes. This class can not be instantiated, only derived from.

DoF index information.

This is packed into a contiguous buffer of the following format:

* [hdr end_0 end_1 ... end_{nps-2} (ncv_0 idx_0 ncv_1 idx_1 ... ncv_nv idx_nv)_0
*                                  (ncv_0 idx_0 ncv_1 idx_1 ... ncv_nv idx_nv)_1
*                                   ...
*                                  (ncv_0 idx_0 ncv_1 idx_1 ... ncv_nv idx_nv)_{nps-2} ]
*

'hdr' determines whether this DofObject has_extra_integers() associated with it; iff so then it is negative.

The total number of "pseudo systems" is nps := abs(hdr).

The total number of true systems is

* ns = hdr,            hdr >= 0
*    = abs(hdr) - 1,   otherwise.
*

'end_s' is the index past the end of the variable group (or integer) storage for (pseudo) system s.

Note: We specifically do not store the end for the last (pseudo) system - this always _idx_buf.size().

As a first example, consider the case of 4 systems, with 3, 0, 1, 2 variable groups, respectively. The _idx_buf then looks like:

* [4 10 10 12 () (ncv_0 idx_0 ncv_1 idx_1 ncv_2 idx_2) () (ncv_0 idx_0) (ncv_0 idx_0 ncv_1 idx_1)]
* [0  1  2  3         4     5     6     7     8     9         10    11      12    13    14    15]
*

The ending index for each (pseudo) system is then given by:

* end_s = _idx_buf.size(),                        s == (nps-1),
*       = _idx_buf[s+1] + has_extra_integers(),   otherwise.
*

The starting indices are not specifically stored, but rather inferred as follows:

start_s = abs(_idx_buf[s])

Now, the defining characteristic of the VariableGroup is that it supports an arbitrary number of variables of the same type. At the DofObject level, what that means is that each Variable in the VariableGroup will have the same number of nonzero components, and they can all be indexed from the same base number. We use this information in the ncv_# and idx_# entries as follows:

ncv_# = n_vars*ncv_magic + n_comp for variable group # idx_# = base_offset for variable group #

the DoF index for a particular component c of variable v within that group is then given by

idx_var = idx_# + n_comp*v + c

Note: There is a subtlety here - "variable v within that group" usually means nothing to the user. This class is either indexed with variable group numbers, or variable numbers counted within the system. So for a system with 2 variable groups, 4 and 8 variables each, the 5th variable in the system is the 1st variable in 2nd variable group. (Now of course 0-base everything... but you get the idea.)

When hdr is negative when cast to a signed type, then we interpret that to mean there exists one pseudo-system following the true systems, one for which the _idx_buf data stores the values associated with add_extra_integer entries, not ncv and idx data associated with system variables. We still return only the number of true systems for n_systems(), but we report has_extra_integers() as true iff hdr is negative, and abs(hdr) will reflect the total number of pseudo-systems, n_systems()+1.

E.g. if we had added two extra integers to the example case above, the _idx_buf then looks like:

* [-5 11 11 13 17 () (ncv_0 idx_0 ncv_1 idx_1 ncv_2 idx_2) () (ncv_0 idx_0) (ncv_0 idx_0 ncv_1 idx_1) (xtra1 xtra2)]
* [0   1  2  3  4         5     6     7     8     9    10         11    12      13    14    15    16      17    18]
*

◆ construct()

Like the copy constructor, this function is also private. We can't use std::make_unique to construct a DofObject since the copy constructor is private, but we can at least encapsulate the code which calls "new" directly.

◆ ncv_magic

const index_t libMesh::DofObject::ncv_magic = 256

Above we introduced the chimera ncv, which is a hybrid of the form ncv = ncv_magic*nv + nc where nv are the number of identical variables of a given type, and nc is the number of components for this set of variables.

It is hoped that by setting this to a power of two, an optimizing compiler will recognize later that #/ncv_magic is simply a bitshift

◆ old_dof_object

std::unique_ptr<DofObject> libMesh::DofObject::old_dof_object

Useful for projecting solutions from one mesh to another.

Public access to old_dof_object is now officially deprecated and will be removed in future libMesh versions. Use the get_old_dof_object() accessor instead.
