NamedSelection | hessian_selection |
A class that selects vectors from a list of named vectors.
Since the number of vectors in a NamedData object may grow with every nesting of applications or loops, it is important to be able to select those, which are actually used in computing residuals etc. This class organizes the selection.
It is used for instance in IntegrationWorker to determine which values, derivatives or second derivatives are actually computed.

Add a vector to the selection of finite element functions. The arguments are the name of the vector and indicators, which information is to be extracted from the vector. The name refers to an entry in a NamedData object, which will be identified by initialize(). The three bool parameters indicate, whether values, greadients and Hessians of the finite element function are to be computed on each cell or face.

|
inline |
Does the same as the function above but it is possible to select a block of the global vector. Initialize the selection field with a data vector. While add() only enters the names of vectors, which will be used in the integration loop over cells and faces, this function links the names to actual vectos in a NamedData object.
