Detailed Description

Attach (glue) a copy of srcG to G, identifying a given set of vertices.

This file does not contain any actual function; rather, the following functions have to be implemented separately for each grid type G1 :

• void EnlargeGrid()
• void EnlargeGridV()
• void EnlargeGridVC()

      template<class G1, class G2, class Geom2, class VertexIdent>
      void
      EnlargeGrid(G1               & destG,     // in/out
                  G2          const& srcG,      // in
                  Geom2       const& srcGeom,   // in
                  VertexIdent const& Iv);       // in

       template<class G1, class G2, class Geom2, class VertexIdent,
                class VertexMap, class CellMap>
       void
       EnlargeGridVC(G1               & destG,       // in/out
                     G2          const& srcG,        // in
                     Geom2       const& srcGeom,     // in
                     VertexIdent const& Iv,          // in  src -> dest
                     VertexMap        & VertexCorr,  // out src -> dest
                     CellMap          & CellCorr);   // out src -> dest

Template parameters:

• G1: The functions are overloaded for concrete types of G1.
• G2, Geom2: same as for ConstructGrid family.
• Iv gives a rule which vertices are to be identified:
  Iv is a injective mapping

Preconditions:

The following preconditions must hold:

• (contains at least one cell)
• 
• 

or more specifically:

• 
• 

may be empty, in which case the result will not be connected.

Postconditions:

The following postconditions will hold (G' is the value of G after execution):

• 
• 
• 

Todo:

EnlargeGrid() , EnlargeGridV() can be defined fully generically in terms of EnlargeGridVC()
