NumLib::LocalToGlobalIndexMap Class Referencefinal

Detailed Description

Row and column indices in global linear algebra objects for each mesh item.

The row and column indices in global matrix and rhs vector for example, required for addition of local contributions from every mesh item (like node or cell) to global objects.

The number of rows should be equal to the number of mesh items and the number of columns should be equal to the number of the components on that mesh item.

Constructor & Destructor Documentation

◆ LocalToGlobalIndexMap() [1/4]

NumLib::LocalToGlobalIndexMap::LocalToGlobalIndexMap ( std::vector< MeshLib::MeshSubset > && mesh_subsets,
NumLib::ComponentOrder const order )

Creates a MeshComponentMap internally and stores the global indices for each mesh element of the given mesh_subsets.

Attention
This constructor assumes the number of the given mesh subsets is equal to the number of variables, i.e. every variable has a single component.

Creates a MeshComponentMap internally and stores the global indices for each mesh element of the given mesh_subsets.

Parameters
mesh_subsetsa vector of components
vec_var_n_componentsa vector of the number of variable components. The size of the vector should be equal to the number of variables. Sum of the entries should be equal to the size of the mesh_subsets.
