Detailed Description

Constructs mappings for the C0 scalar continuous Galerkin formulation.

Mappings are created for three possible global solution types:

These mappings are used by GlobalLinSys to generate the global system.

Nektar::MultiRegions::AssemblyMapCG::AssemblyMapCG ( const LibUtilities::SessionReaderSharedPtr pSession,
const int  numLocalCoeffs,
const ExpList locExp,
const BndCondExp bndCondExp = NullExpListSharedPtrArray,

const bool  checkIfSingular = false,
const std::string  variable = "defaultVar",
const PeriodicMap periodicVerts = NullPeriodicMap,
const PeriodicMap periodicEdges = NullPeriodicMap,
const PeriodicMap periodicFaces = NullPeriodicMap 
)

General constructor for expansions of all dimensions without boundary conditions.

STEP 6: 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.

void Nektar::MultiRegions::AssemblyMapCG::CalculateFullSystemBandWidth ( )
protected

Calculate the bandwith of the full matrix system.

The bandwidth calculated here corresponds to what is referred to as half-bandwidth. If the elements of the matrix are designated as a_ij, it corresponds to the maximum value of |i-j| for non-zero a_ij. As a result, the value also corresponds to the number of sub- or super-diagonals.

The bandwith can be calculated elementally as it corresponds to the maximal elemental bandwith (i.e. the maximal difference in global DOF index for every element).

We caluclate here the bandwith of the full global system.

AssemblyMapSharedPtr Nektar::MultiRegions::AssemblyMapCG::v_LinearSpaceMap ( const ExpList locexp,
GlobalSysSolnType  solnType 
)
protectedvirtual

Construct an AssemblyMapCG object which corresponds to the linear space of the current object.

This function is used to create a linear-space assembly map, which is then used in the linear space preconditioner in the conjugate gradient solve.

Reimplemented from Nektar::MultiRegions::AssemblyMap.
