Given the elemental coefficients $\hat{u}_n^e$ of an expansion, this function evaluates the spectral/hp expansion $u^{\delta}(\boldsymbol{x})$ at the quadrature points $\boldsymbol{x}_i$ . The operation is evaluated locally by the elemental function StdRegions::StdExpansion::BwdTrans.

Parameters

inarray	An array of size $N_{\mathrm{eof}}$ containing the local coefficients $\hat{u}_n^e$ .
outarray	The resulting physical values at the quadrature points $u^{\delta}(\boldsymbol{x}_i)$ will be stored in this array of size $Q_{\mathrm{tot}}$ .

protectedvirtual

Given a function $u(\boldsymbol{x})$ defined at the quadrature points, this function determines the transformed elemental coefficients $\hat{u}_n^e$ employing a discrete elemental Galerkin projection from physical space to coefficient space. For each element, the operation is evaluated locally by the function StdRegions::StdExpansion::IproductWRTBase followed by a call to #MultiRegions#MultiplyByElmtInvMass.

Parameters

inarray	An array of size $Q_{\mathrm{tot}}$ containing the values of the function $f(\boldsymbol{x})$ at the quadrature points $\boldsymbol{x}_i$ .
outarray	The resulting coefficients $\hat{u}_n^e$ will be stored in this array of size $N_{\mathrm{eof}}$ .

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.
