Construct a global continuous field.

Given a mesh graph2D, containing information about the domain and the spectral/hp element expansion, this constructor fills the list of local expansions m_exp with the proper expansions, calculates the total number of quadrature points \(\boldsymbol{x}_i\) and local expansion coefficients \(\hat{u}^e_n\) and allocates memory for the arrays m_coeffs and m_phys. Furthermore, it constructs the mapping array (contained in m_locToGloMap) for the transformation between local elemental level and global level, it calculates the total number global expansion coefficients \(\hat{u}_n\) and allocates memory for the array m_coeffs. The constructor also discretises the boundary conditions, specified by the argument bcs, by expressing them in terms of the coefficient of the expansion on the boundary.

Parameters

pSession	Session information.
graph3D	A mesh, containing information about the domain and the spectral/hp element expansion.
variable	The variable associated with this field.

	)

Construct a global continuous field with solution type based on another field but using a separate input mesh and boundary conditions.

Given a mesh graph3D, containing information about the domain and the spectral/hp element expansion, this constructor fills the list of local expansions m_exp with the proper expansions, calculates the total number of quadrature points \(\boldsymbol{x}_i\) and local expansion coefficients \(\hat{u}^e_n\) and allocates memory for the arrays m_coeffs and m_phys. Furthermore, it constructs the mapping array (contained in m_locToGloMap) for the transformation between local elemental level and global level, it calculates the total number global expansion coefficients \(\hat{u}_n\) and allocates memory for the array m_coeffs. The constructor also discretises the boundary conditions, specified by the argument bcs, by expressing them in terms of the coefficient of the expansion on the boundary.

Parameters

In	Existing ContField2D object used to provide the local to global mapping information and global solution type.
graph3D	A mesh, containing information about the domain and the spectral/hp element expansion.
bcs	The boundary conditions.

Performs the backward transformation of the spectral/hp element expansion.

Given the coefficients of an expansion, this function evaluates the spectral/hp expansion \(u^{\delta}(\boldsymbol{x})\) at the quadrature points \(\boldsymbol{x}_i\). This operation is evaluated locally by the function ExpList::BwdTrans.

The coefficients of the expansion should be contained in the variable #inarray of the ExpList object In. The resulting physical values at the quadrature points \(u^{\delta}(\boldsymbol{x}_i)\) are stored in the array #outarray.

Parameters

In	An ExpList, containing the local coefficients \(\hat{u}_n^e\) in its array m_coeffs.

void Nektar::MultiRegions::ContField3D::v_IProductWRTBase ( const Array< OneD, const NekDouble > &  inarray, Array< OneD, NekDouble > &  outarray, CoeffState  coeffstate = eLocal  )

protectedvirtual

Calculates the inner product of a function \(f(\boldsymbol{x})\) with respect to all global expansion modes \(\phi_n^e(\boldsymbol{x})\).

The operation is evaluated locally (i.e. with respect to all local expansion modes) by the function ExpList::IProductWRTBase. The inner product with respect to the global expansion modes is than obtained by a global assembly operation.

The values of the function \(f(\boldsymbol{x})\) evaluated at the quadrature points \(\boldsymbol{x}_i\) should be contained in the variable m_phys of the ExpList object in. The result is stored in the array m_coeffs.

Parameters

In	An ExpList, containing the discrete evaluation of \(f(\boldsymbol{x})\) at the quadrature points in its array m_phys.
