This module groups a diverse set of classes that generally implement some sort of numerical algorithm on top all the basic triangulation, DoFHandler, and finite element classes in the library. They are generally unconnected to each other.
Some of the classes, like DerivativeApproximation, KellyErrorEstimator and SolutionTransfer, act on solutions already obtained, and compute derived quantities in the first two cases, or help transferring a set of vectors from one mesh to another.
The remaining classes MatrixCreator, MatrixTools, and VectorTools provide an assortment of services, such as creating a Laplac matrix, projecting or interpolating a function onto the present finite element space, etc. The difference to the functions in the DoFTools and FETools functions is that they work on vectors (i.e. members of a finite element function space on a given triangulation) or help in the creation of it. On the other hand, the DoFTools functions only act on a given DoFHandler object without reference to a data vector, and the FETools objects generally work with finite element classes but again without any associated data vectors.

Declaration of PreparationState
that denotes the three possible states of the SolutionTransfer:
being prepared for 'pure refinement', prepared for 'coarsening and refinement' or not prepared.

Denote which norm/integral is to be computed by the integrate_difference() function of this class. The following possibilities are implemented:
Enumerator | |
---|---|
mean |
The function or difference of functions is integrated on each cell. |
L1_norm |
The absolute value of the function is integrated. |
L2_norm |
The square of the function is integrated and the the square root of the result is computed on each cell. |
Lp_norm |
The absolute value to the pth power is integrated and the pth root is computed on each cell. The exponent p is the last parameter of the function. |
Linfty_norm |
The maximum absolute value of the function. |
H1_seminorm |
L2_norm of the gradient. |
H1_norm |
The square of this norm is the square of the L2_norm plus the square of the H1_seminorm. |
W1p_seminorm |
Lp_norm of the gradient. |
W1p_norm |
same as H1_norm for Lp. |
W1infty_seminorm |
Linfty_norm of the gradient. |
W1infty_norm |
same as H1_norm for Linfty. |
