Member Function Documentation

void Nektar::StdRegions::StdSegExp::v_BwdTrans ( const Array< OneD, const NekDouble > &  inarray,
Array< OneD, NekDouble > &  outarray 
)
protectedvirtual

Backward transform from coefficient space given in inarray and evaluate at the physical quadrature points outarray.

Operation can be evaluated as $ u(\xi_{1i}) = \sum_{p=0}^{order-1} \hat{u}_p \phi_p(\xi_{1i}) $ or equivalently $ {\bf u} = {\bf B}^T {\bf \hat{u}} $ where ${\bf B}[i][j] = \phi_i(\xi_{1j}), \mbox{\_coeffs}[p] = {\bf \hat{u}}[p] $

The function takes the coefficient array inarray as input for the transformation

Parameters
inarraythe coeffficients of the expansion
outarraythe resulting array of the values of the function at the physical quadrature points will be stored in the array outarray

void Nektar::StdRegions::StdSegExp::v_FwdTrans ( const Array< OneD, const NekDouble > &  inarray,
Array< OneD, NekDouble > &  outarray 
)
protectedvirtual

Forward transform from physical quadrature space stored in inarray and evaluate the expansion coefficients and store in outarray.

Perform a forward transform using a Galerkin projection by taking the inner product of the physical points and multiplying by the inverse of the mass matrix using the Solve method of the standard matrix container holding the local mass matrix, i.e. $ {\bf \hat{u}} = {\bf M}^{-1} {\bf I} $ where $ {\bf I}[p] = \int^1_{-1} \phi_p(\xi_1) u(\xi_1) d\xi_1 $

This function stores the expansion coefficients calculated by the transformation in the coefficient space array outarray

Parameters
inarrayarray of physical quadrature points to be transformed
outarraythe coeffficients of the expansion

Calculate $ I[p] = \int^{1}_{-1} \phi_p(\xi_1) u(\xi_1) d\xi_1 = \sum_{i=0}^{nq-1} \phi_p(\xi_{1i}) u(\xi_{1i}) w_i $ where $ outarray[p] = I[p], inarray[i] = u(\xi_{1i}), base[p*nq+i] = \phi_p(\xi_{1i}) $.

Parameters
basean array defining the local basis for the inner product usually passed from Basis->GetBdata() or Basis->GetDbdata()
inarrayphysical point array of function to be integrated $ u(\xi_1) $
coll_checkflag to identify when a Basis->Collocation() call should be performed to see if this is a GLL_Lagrange basis with a collocation property. (should be set to 0 if taking the inner product with respect to the derivative of basis)
outarraythe values of the inner product with respect to each basis over region will be stored in the array outarray as output of the function
