Array< OneD, NekDouble > &  outarray_d3 
)

Calculate the 3D derivative in the local tensor/collapsed coordinate at the physical points.

This function is independent of the expansion basis and can therefore be defined for all tensor product distribution of quadrature points in a generic manner. The key operations are:

  • \( \frac{d}{d\eta_1} \rightarrow {\bf D^T_0 u } \)
  • \( \frac{d}{d\eta_2} \rightarrow {\bf D_1 u } \)
  • \( \frac{d}{d\eta_3} \rightarrow {\bf D_2 u } \)
Parameters
inarrayarray of physical points to be differentiated
outarray_d1the resulting array of derivative in the \(\eta_1\) direction will be stored in outarray_d1 as output of the function
outarray_d2the resulting array of derivative in the \(\eta_2\) direction will be stored in outarray_d2 as output of the function
outarray_d3the resulting array of derivative in the \(\eta_3\) direction will be stored in outarray_d3 as output of the function

Recall that: \( \hspace{1cm} \begin{array}{llll} \mbox{Shape} & \mbox{Cartesian coordinate range} & \mbox{Collapsed coord.} & \mbox{Collapsed coordinate definition}\\ \mbox{Hexahedral} & -1 \leq \xi_1,\xi_2, \xi_3 \leq 1 & -1 \leq \eta_1,\eta_2, \eta_3 \leq 1 & \eta_1 = \xi_1, \eta_2 = \xi_2, \eta_3 = \xi_3 \\ \mbox{Tetrahedral} & -1 \leq \xi_1,\xi_2,\xi_3; \xi_1+\xi_2 +\xi_3 \leq -1 & -1 \leq \eta_1,\eta_2, \eta_3 \leq 1 & \eta_1 = \frac{2(1+\xi_1)}{-\xi_2 -\xi_3}-1, \eta_2 = \frac{2(1+\xi_2)}{1 - \xi_3}-1, \eta_3 = \xi_3 \\ \end{array} \)

const Array< OneD, const NekDouble > &  physvals 
)
overrideprotectedvirtual

This function evaluates the expansion at a single (arbitrary) point of the domain.

Based on the value of the expansion at the quadrature points, this function calculates the value of the expansion at an arbitrary single points (with coordinates \( \mathbf{x_c}\) given by the pointer coords). This operation, equivalent to

\[ u(\mathbf{x_c}) = \sum_p \phi_p(\mathbf{x_c}) \hat{u}_p \]

is evaluated using Lagrangian interpolants through the quadrature points:

\[ u(\mathbf{x_c}) = \sum_p h_p(\mathbf{x_c}) u_p\]

This function requires that the physical value array \(\mathbf{u}\) (implemented as the attribute #phys) is set.

Parameters
coordsthe coordinates of the single point
Returns
returns the value of the expansion at the single point
