CSRMatrix SimPT_Sim::MeshTopology::NodeCellNodeIncidence ( std::shared_ptr< Mesh >  mesh)
static

Return the incidence of nodes and cells as a binary CSR matrix A with dimensions: #nodes x #cells.

Rows are nodes, columns are cells. A nonzero element at position (i,j) indicates that a node i is incident with cell j.

The notion of "incidence" in the context of this function is defined as: "Node i belongs to the polygon of a cell j".

CSRMatrix SimPT_Sim::MeshTopology::NodeEdgeNodeIncidence ( std::shared_ptr< Mesh >  mesh)
static

Return the incidence of nodes and nodes as a binary CSR matrix A with dimensions: #nodes x #nodes.

Rows and columns are nodes. A nonzero element at position (i,j) indicates that a node i is incident with node j.

The notion of "incidence" in the context of this function is defined as: "Node i shares an edge with node j".
