Detailed Description

Class to store bi-directional lookup between added matrix row/col numbers to main matrix (SumOfMatrix) row/col numbers.

Constructor & Destructor Documentation

oomph::AddedMainNumberingLookup::AddedMainNumberingLookup ( )
inline

Default constructor.

Definition at line 57 of file sum_of_matrices.h.

oomph::AddedMainNumberingLookup::AddedMainNumberingLookup ( const Mesh mesh_pt,
const unsigned &  dof_index 
)
inline

Real constructor: construct lookup from node numbers in mesh and global equation numbers. Useful for the case when the main matrix is a Jacobian and the added matrix is a contribution only on a certain mesh.

Definition at line 63 of file sum_of_matrices.h.

oomph::AddedMainNumberingLookup::AddedMainNumberingLookup ( const int *  lookup_array,
const unsigned &  length 
)
inline

Construct lookup schemes from int array (HLib's format for this data).

Definition at line 70 of file sum_of_matrices.h.

oomph::AddedMainNumberingLookup::~AddedMainNumberingLookup ( )
inline

Destructor.

Definition at line 76 of file sum_of_matrices.h.

oomph::AddedMainNumberingLookup::AddedMainNumberingLookup ( const AddedMainNumberingLookup dummy)
inlineprivate

Inaccessible copy constructor.

Member Data Documentation

Vector<unsigned> oomph::AddedMainNumberingLookup::Added_to_main_mapping
private

Mapping from added matrix row/col numbers to main matrix row/col numbers.

Definition at line 237 of file sum_of_matrices.h.

std::map<unsigned, unsigned> oomph::AddedMainNumberingLookup::Main_to_added_mapping
private

Mapping from main matrix row/col numbers to added matrix row/col numbers. Note that we cannot use a vector here because the main matrix rows/cols mapped onto are probably not contiguous. Access times are O(log N) so if you need to iterate over all elements then use the pointer access functions and use stl iterators properly.
