The integration is evaluated locally, that is

\[\int f(\boldsymbol{x})d\boldsymbol{x}=\sum_{e=1}^{{N_{\mathrm{el}}}} \left\{\int_{\Omega_e}f(\boldsymbol{x})d\boldsymbol{x}\right\}, \]

where the integration over the separate elements is done by the function StdRegions::StdExpansion::Integral, which discretely evaluates the integral using Gaussian quadrature.

Parameters

inarray

An array of size \(Q_{\mathrm{tot}}\) containing the values of the function \(f(\boldsymbol{x})\) at the quadrature points \(\boldsymbol{x}_i\).

Returns

The value of the discretely evaluated integral \(\int f(\boldsymbol{x})d\boldsymbol{x}\).

v_PhysDeriv() [1/2]

void Nektar::MultiRegions::ExpListHomogeneous1D::v_PhysDeriv ( const Array< OneD, const NekDouble > &  inarray, Array< OneD, NekDouble > &  out_d0, Array< OneD, NekDouble > &  out_d1, Array< OneD, NekDouble > &  out_d2  )

overrideprotectedvirtual

Given a function \(f(\boldsymbol{x})\) evaluated at the quadrature points, this function calculates the derivatives \(\frac{d}{dx_1}\), \(\frac{d}{dx_2}\) and \(\frac{d}{dx_3}\) of the function \(f(\boldsymbol{x})\) at the same quadrature points. The local distribution of the quadrature points allows an elemental evaluation of the derivative. This is done by a call to the function StdRegions::StdExpansion::PhysDeriv.

Parameters

inarray	An array of size \(Q_{\mathrm{tot}}\) containing the values of the function \(f(\boldsymbol{x})\) at the quadrature points \(\boldsymbol{x}_i\).
out_d0	The discrete evaluation of the derivative \(\frac{d}{dx_1}\) will be stored in this array of size \(Q_{\mathrm{tot}}\).
out_d1	The discrete evaluation of the derivative \(\frac{d}{dx_2}\) will be stored in this array of size \(Q_{\mathrm{tot}}\). Note that if no memory is allocated for out_d1, the derivative \(\frac{d}{dx_2}\) will not be calculated.
out_d2	The discrete evaluation of the derivative \(\frac{d}{dx_3}\) will be stored in this array of size \(Q_{\mathrm{tot}}\). Note that if no memory is allocated for out_d2, the derivative \(\frac{d}{dx_3}\) will not be calculated.
