Public Member Functions
	GmpCellMeshDataBase (GmCellMesh *mesh)
	Constructor.
	~GmpCellMeshDataBase ()
	Destructor. Clears our entry in the global _meshTable and _meshDataTable.
bool	hierarchicalElements () const
	Returns true if the mesh uses hierarchical elements, false otherwise.
bool	setHierarchicalIndex (int p, int q)
	Sets the hierarchical index for this mesh from the given P & Q element orders. Returns false if not possible.

Static Public Member Functions
static int	hierarchicalOrderIndex (int P, int Q)
	Returns the table index that matches the given hierarchical element P & Q orders or -1 if (P, Q) forms a new order and the internal table already includes GmpCellMeshDataMaxHTypes entries.
static int	hierarchicalPOrder (int index)
	Returns the P order for hierarchical elements associated with the given index (returned by hierarchicalOrderIndex()), or 0 if elements are not hierarchical.
static int	hierarchicalQOrder (int index)
	Returns the Q order for hierarchical elements associated with the given index (returned by hierarchicalOrderIndex()), or 0 if elements are not hierarchical.
static int	newMeshId (GmCellMesh *mesh, GmpCellMeshDataBase *data)
	Returns the next available mesh id, storing mesh in the mesh table at the returned index. If no room exists for a new mesh, returns -1.

Detailed Description

A non template base class for GmpCellMeshData storing the needed static attributes to controll the global mesh set and hierarchical cell options.

Member Function Documentation

hierarchicalOrderIndex()

int GmpCellMeshDataBase::hierarchicalOrderIndex ( int P, int Q )

static

Returns the table index that matches the given hierarchical element P & Q orders or -1 if (P, Q) forms a new order and the internal table already includes GmpCellMeshDataMaxHTypes entries.

When working with hierarchical elements, the element's P & Q order are mesh parameters, but to allow an hierarchical element to return the appropriate shape function (parameterized by P & Q) without access to the mesh, those parameters are added to the element type by using template parameters (so that they do not use space in the element definition). Since P & Q are conceptually any integer numbers, and the templates must be resolved at compile time, it is not feasible to create a template specialization for each possible pair of P & Q. Instead, we store in _hTable the set of used pairs for the whole simulation (keep in mind that each mesh uses only one pair) and add to the cell type only the index of P & Q in the table, limiting the table size.

meshData()

static GmpCellMeshDataBase * GmpCellMeshDataBase::meshData ( int meshId )

inlinestatic

Returns the mesh data pointer associated with the given mesh id.

Stores the mesh index in _meshTable for the current mesh
