Constructor & Destructor Documentation

Nektar::CoupledLocalToGlobalC0ContMap::CoupledLocalToGlobalC0ContMap ( const LibUtilities::SessionReaderSharedPtr &  pSession,
const SpatialDomains::MeshGraphSharedPtr &  graph,
const SpatialDomains::BoundaryConditionsSharedPtr &  boundaryConditions,
const Array< OneD, MultiRegions::ExpListSharedPtr > &  fields,
const MultiRegions::ExpListSharedPtr &  pressure,
const int  nz_loc,
const bool  CheckforSingularSys = true 
)

This is an vector extension of MultiRegion::LocalToGlobalC0BaseMap::SetUp2DExpansionC0ContMap related to the Linearised Navier Stokes problem

STEP 1: Wrap boundary conditions vector in an array (since routine is set up for multiple fields) and call the graph re-odering subroutine to obtain the reordered values

: Fix this so that we can extract normals from edges

STEP 2a: Set the mean pressure modes to edges depending on type of direct solver technique;

STEP 2: Count out the number of Dirichlet vertices and edges first

STEP 3: Set up an array which contains the offset information of the different graph vertices.

This basically means to identify how many global degrees of freedom the individual graph vertices correspond. Obviously, the graph vertices corresponding to the mesh-vertices account for a single global DOF. However, the graph vertices corresponding to the element edges correspond to 2*(N-2) global DOF where N is equal to the number of boundary modes on this edge.

STEP 4: Now, all ingredients are ready to set up the actual local to global mapping.

The remainder of the map consists of the element-interior degrees of freedom. This leads to the block-diagonal submatrix as each element-interior mode is globally orthogonal to modes in all other elements.

STEP 5: The boundary condition mapping is generated from the same vertex renumbering and fill in a unique interior map.
