Nektar::CoupledAssemblyMap::CoupledAssemblyMap ( const LibUtilities::SessionReaderSharedPtr pSession,
const SpatialDomains::MeshGraphSharedPtr graph,
const MultiRegions::AssemblyMapCGSharedPtr cgMap,
const Array< OneD, const BoundaryCondShPtr > &  boundaryConditions,
const Array< OneD, MultiRegions::ExpListSharedPtr > &  fields 
)

Take an existing assembly map and create a coupled version suitable for use in the linear elasticity solver.

The linear elasticity solver requires a slight reordering of local and global coefficients to support problems of the form

[ A B C ] [ u ] = [ f_u ] [ D E F ] [ v ] [ f_v ] [ G H I ] [ w ] [ f_w ]
