Detailed Description

Abstraction of a two-dimensional multi-elemental expansion which is merely a collection of local expansions.

This multi-elemental expansion, which does not exhibit any coupling between the expansion on the separate elements, can be formulated as,

\[u^{\delta}(\boldsymbol{x}_i)=\sum_{e=1}^{{N_{\mathrm{el}}}} \sum_{n=0}^{N^{e}_m-1}\hat{u}_n^e\phi_n^e(\boldsymbol{x}_i).\]

where ${N_{\mathrm{el}}}$ is the number of elements and $N^{e}_m$ is the local elemental number of expansion modes. This class inherits all its variables and member functions from the base class ExpList.

const Collections::ImplementationType  ImpType = Collections::eNoImpType 
)

Sets up a list of local expansions based on an input mesh.

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.

Parameters
graph2DA mesh, containing information about the domain and the spectral/hp element expansion.

Given an expansion vector expansions, 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.

Parameters
expansionsA vector containing information about the domain and the spectral/hp element expansion.
