Member Function Documentation

Epetra_MultiVector * Galeri::core::Workspace::createMultiVectorComponent ( const Epetra_MultiVector &  input  )  [static]

Creates a multivector that can hold a component of the specified multivector.

From the input Epetra_MultiVector, defined on an Epetra_BlockMap, defines a new Epetra_Map that can host one component of the multivector, and allocates an Epetra_MultiVector based on it. This is useful in vector problems, when the input vector contains several PDE componets, and one of them has to be extracted.
