void Nektar::StdRegions::StdExpansion3D::PhysTensorDeriv	(	const Array< OneD, const NekDouble > &	inarray,
		Array< OneD, NekDouble > &	outarray_d1,
		Array< OneD, NekDouble > &	outarray_d2,
		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

inarray	array of physical points to be differentiated
outarray_d1	the resulting array of derivative in the $\eta_1$ direction will be stored in outarray_d1 as output of the function
outarray_d2	the resulting array of derivative in the $\eta_2$ direction will be stored in outarray_d2 as output of the function
outarray_d3	the resulting array of derivative in the $\eta_3$ direction will be stored in outarray_d3 as output of the function

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

NekDouble Nektar::StdRegions::StdExpansion3D::v_PhysEvaluate	(	const Array< OneD, const NekDouble > &	coords,
		const Array< OneD, const NekDouble > &	physvals
	)

protectedvirtual

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

coords the coordinates of the single point

Returns: returns the value of the expansion at the single point
