    Requires cell topology with a reference cell. Admissible ranks and dimensions of the
    input point array and the corresponding rank and dimension of the output array are as follows:

        |-------------------|-------------|-------------|-------------|

		const Kokkos::DynRankView< worksetJacobianValueType, worksetJacobianProperties...>	worksetJacobians,
		const ordinal_type	worksetEdgeOrd,
		const shards::CellTopology	parentCell
	)

static

Computes non-normalized tangent vectors to physical edges in an edge workset $\{\mathcal{E}_{c,i}\}_{c=0}^{N}$ ; (see Subcell worksets for definition of edge worksets).

For every edge in the workset the tangents are computed at the points ${\bf x}_p = F_c(\hat{\Phi}_i(t_p))\in\mathcal{E}_{c,i}$ that are images of points from R=[-1,1] on edge $\mathcal{E}_{c,i}$ . Returns rank-3 array with dimensions (C,P,D1), D1=2 or D1=3 such that

${edgeTangents}(c,p,d) = DF_c(\hat{\Phi}_i(t_p))\cdot {\partial{\hat{\Phi}}_{i}(t_p)\over\partial t}\,; \qquad t_p \in R$

In this formula:

is Jacobian of parent cell ${\mathcal C}$ that owns physical edge ${\mathcal E}_{c,i}$ ;
${\partial{\hat{\Phi}}_{i}/\partial t}$ is the (constant) tangent to reference edge $\hat{\mathcal E}_i$ ; see Intrepid2::CellTools::getReferenceEdgeTangent that has the same local ordinal as the edges in the workset;
$\hat{\Phi}_i R\mapsto\hat{\mathcal E}_i$ is parametrization of reference edge $\hat{\mathcal E}_i$ ;

Warning: worksetJacobians must contain the values of $DF_c(\hat{\Phi}_i(t_p))$ , where $t_p \in R=[-1,1]$ , i.e., Jacobians of the parent cells evaluated at points that are located on reference edge $\hat{\mathcal E}_i$ having the same local ordinal as the edges in the workset.

Parameters

edgeTangents	[out] - rank-3 array (C,P,D1) with tangents on workset edges
worksetJacobians	[in] - rank-4 array (C,P,D1,D1) with Jacobians evaluated at ref. edge points
worksetEdgeOrd	[in] - edge ordinal, relative to ref. cell, of the edge workset
parentCell	[in] - cell topology of the parent reference cell

		const Kokkos::DynRankView< worksetJacobianValueType, worksetJacobianProperties...>	worksetJacobians,
		const ordinal_type	worksetFaceOrd,
		const shards::CellTopology	parentCell
	)

static

Computes non-normalized normal vectors to physical faces in a face workset $\{\mathcal{F}_{c,i}\}_{c=0}^{N}$ ; (see Subcell worksets for definition of face worksets).

For every face in the workset the normals are computed at the points ${\bf x}_p = F_c(\hat{\Phi}_i(u_p,v_p))\in\mathcal{F}_{c,i}$ that are images of points from the parametrization domain R on face $\mathcal{F}_{c,i}$ . Returns rank-3 array with dimensions (C,P,D), D=3, such that

${faceNormals}(c,p,d) = \left( DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_i\over\partial u}\right) \times \left( DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_i\over\partial v}\right) \,; \qquad (u_p, v_p) \in R \,.$

In this formula:

is Jacobian of parent cell ${\mathcal C}$ that owns physical face ${\mathcal F}_{c,i}$ ;
${\partial\hat{\Phi}_i/\partial u}, {\partial\hat{\Phi}_i/\partial v}$ are the (constant) tangents on reference face $\hat{\mathcal F}_i$ ; see Intrepid2::CellTools::getReferenceFaceTangents; that has the same local ordinal as the faces in the workset;
$\hat{\Phi}_i : R\mapsto \hat{\mathcal F}_i$ is parametrization of reference face $\hat{\mathcal F}_i$ ;
R is the parametrization domain for reference face $\hat{\mathcal F}_i$ :
$R = \left\{\begin{array}{rl} \{(0,0),(1,0),(0,1)\} & \mbox{if $\hat{\mathcal F}_i$ is Triangle} \\[1ex] [-1,1]\times [-1,1] & \mbox{if $\hat{\mathcal F}_i$ is Quadrilateral} \end{array}\right.$

Warning: worksetJacobians must contain the values of $DF_c(\hat{\Phi}_i(u_p,v_p))$ , where $(u_p,v_p)\in R$ , i.e., Jacobians of the parent cells evaluated at points that are located on reference face $\hat{\mathcal F}_i$ having the same local ordinal as the faces in the workset.

Parameters

faceNormals	[out] - rank-3 array (C,P,D), normals at workset faces
worksetJacobians	[in] - rank-4 array (C,P,D,D) with Jacobians at ref. face points
worksetFaceOrd	[in] - face ordinal, relative to ref. cell, of the face workset
parentCell	[in] - cell topology of the parent reference cell

static

Computes non-normalized tangent vector pairs to physical faces in a face workset $\{\mathcal{F}_{c,i}\}_{c=0}^{N}$ ; (see Subcell worksets for definition of face worksets).

For every face in the workset the tangents are computed at the points ${\bf x}_p = F_c(\hat{\Phi}_i(u_p,v_p))\in\mathcal{F}_{c,i}$ that are images of points from the parametrization domain R on face $\mathcal{F}_{c,i}$ . Returns 2 rank-3 arrays with dimensions (C,P,D), D=3 such that

${faceTanU}(c,p,d) = DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_i\over\partial u};\qquad {faceTanV}(c,p,d) = DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_{i}\over\partial v}\,; \qquad (u_p, v_p) \in R \,.$

In this formula:

is Jacobian of parent cell ${\mathcal C}$ that owns physical face ${\mathcal F}_{c,i}$ ;
${\partial\hat{\Phi}_i/\partial u}, {\partial\hat{\Phi}_i/\partial v}$ are the (constant) tangents on reference face $\hat{\mathcal F}_i$ ; see Intrepid2::CellTools::getReferenceFaceTangents; that has the same local ordinal as the faces in the workset;

Warning: worksetJacobians must contain the values of $DF_c(\hat{\Phi}_i(u_p,v_p))$ , where $(u_p,v_p)\in R$ , i.e., Jacobians of the parent cells evaluated at points that are located on reference face $\hat{\mathcal F}_i$ having the same local ordinal as the faces in the workset.

For every side in the workset the normals are computed at the points ${\bf x}_p = F_c(\hat{\Phi}_i(P_p))\in\mathcal{S}_{c,i}$ that are images of points from the parametrization domain R on side $\mathcal{S}_{c,i}$ . A side is defined as a subcell of dimension one less than that of its parent cell. Therefore, sides of 2D cells are 1-subcells (edges) and sides of 3D cells are 2-subcells (faces).

Returns rank-3 array with dimensions (C,P,D), D = 2 or 3, such that

${sideNormals}(c,p,d) = \left\{\begin{array}{crl} \displaystyle \left(DF_c(\hat{\Phi}_i(t_p))\cdot {\partial{\hat{\Phi}}_{i}(t_p)\over\partial t}\right)^{\perp} & t_p\in R & \mbox{for 2D parent cells} \\[2ex] \displaystyle \left( DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_i\over\partial u}\right) \times \left( DF_c(\hat{\Phi}_i(u_p, v_p))\cdot {\partial\hat{\Phi}_i\over\partial v}\right) \,; & (u_p, v_p) \in R & \mbox{for 3D parent cells} \end{array}\right.$

In this formula:

is Jacobian of parent cell ${\mathcal C}$ that owns physical side ${\mathcal S}_{c,i}$ ;
For 2D cells: ${\partial{\hat{\Phi}}_{i}/\partial t}$ is the (constant) tangent to reference side (edge) $\hat{\mathcal S}_i$ ; see Intrepid2::CellTools::getReferenceEdgeTangent, that has the same local ordinal as the sides in the workset;
For 3D cells: ${\partial\hat{\Phi}_i/\partial u}, {\partial\hat{\Phi}_i/\partial v}$ are the (constant) tangents on reference side (face) $\hat{\mathcal S}_i$ ; see Intrepid2::CellTools::getReferenceFaceTangents, that has the same local ordinal as the sides in the workset;
$\hat{\Phi}_i : R\mapsto \hat{\mathcal S}_i$ is parametrization of reference side $\hat{\mathcal S}_i$ ;
R is the parametrization domain for reference side $\hat{\mathcal S}_i$ . For 2D parent cells R=[-1,1] and for 3D parent cells
$R = \left\{\begin{array}{rl} \{(0,0),(1,0),(0,1)\} & \mbox{if $\hat{\mathcal S}_i$ is Triangle} \\[1ex] [-1,1]\times [-1,1] & \mbox{if $\hat{\mathcal S}_i$ is Quadrilateral} \end{array}\right.$

Remarks

For 3D cells the physical side normals coincides with the face normals computed by Intrepid2::CellTools::getPhysicalFaceNormals and these two methods are completely equivalent.
For 2D cells the physical side normals are defined by ${\bf n}=(t_2,-t_1)$ where ${\bf t}=(t_1,t_2)$ are the physical edge tangents computed by Intrepid2::CellTools::getPhysicalEdgeTangents. Therefore, the pairs $({\bf n},{\bf t})$ are positively oriented.

Warning: worksetJacobians must contain the values of $DF_c(\hat{\Phi}_i(P_p))$ , where $P_p\in R$ , i.e., Jacobians of the parent cells evaluated at points that are located on reference side $\hat{\mathcal S}_i$ having the same local ordinal as the sides in the workset.

Parameters

sideNormals	[out] - rank-3 array (C,P,D), normals at workset sides
worksetJacobians	[in] - rank-4 array (C,P,D,D) with Jacobians at ref. side points
worksetSideOrd	[in] - side ordinal, relative to ref. cell, of the side workset
parentCell	[in] - cell topology of the parent reference cell

	)

static

Computes constant tangent vectors to edges of 2D or 3D reference cells.

Returns rank-1 array with dimension (D), D=2 or D=3; such that

${refEdgeTangent}(*) = \hat{\bf t}_i = {\partial\hat{\Phi}_i(t)\over\partial t}\,,$

where $\hat{\Phi}_i : R =[-1,1]\mapsto \hat{\mathcal E}_i$ is the parametrization map of the specified reference edge $\hat{\mathcal E}_i$ , given by

$\hat{\Phi}_i(t) = \left\{\begin{array}{ll} (\hat{x}(t),\hat{y}(t),\hat{z}(t)) & \mbox{for 3D parent cells} \\[1ex] (\hat{x}(t),\hat{y}(t)) & \mbox{for 2D parent cells} \\[1ex] \end{array}\right.$

The length of computed edge tangents is one-half the length of their associated edges:

$|\hat{\bf t}_i | = {1\over 2} |\hat{\mathcal E}_i |\,.$

Because the edges of all reference cells are always affine images of [-1,1], the edge tangent is constant vector field.

Parameters

refEdgeTangent	[out] - rank-1 array (D) with the edge tangent; D = cell dimension
edgeOrd	[in] - ordinal of the edge whose tangent is computed

static

Computes constant normal vectors to faces of 3D reference cell.

Returns rank-1 array with dimension (D), D=3 such that

${refFaceNormal}(*) = \hat{\bf n}_i = {\partial\hat{\Phi}_{i}\over\partial u} \times {\partial\hat{\Phi}_{i}\over\partial v}$

where $\hat{\Phi}_i: R \mapsto \hat{\mathcal F}_i$ is the parametrization map of the specified reference face $\hat{\mathcal F}_i$ given by

$\hat{\Phi}_i(u,v) =(\hat{x}(u,v),\hat{y}(u,v),\hat{z}(u,v))$

and

The length of computed face normals is proportional to face area:

$|\hat{\bf n}_i | = \left\{\begin{array}{rl} 2 \mbox{Area}(\hat{\mathcal F}_i) & \mbox{if $\hat{\mathcal F}_i$ is Triangle} \\[1ex] \mbox{Area}(\hat{\mathcal F}_i) & \mbox{if $\hat{\mathcal F}_i$ is Quadrilateral} \,. \end{array}\right.$

Because the faces of all reference cells are always affine images of R , the coordinate functions $\hat{x},\hat{y},\hat{z}$ of the parametrization map are linear and the face normal is a constant vector.

Remarks: The method Intrepid2::CellTools::getReferenceFaceTangents computes the reference face tangents ${\partial\hat{\Phi}_{i}/\partial u}$ and ${\partial\hat{\Phi}_{i}/\partial v}$ .

Returns 2 rank-1 arrays with dimension (D), D=3, such that

Because the faces of all reference cells are always affine images of R , the coordinate functions $\hat{x},\hat{y},\hat{z}$ of the parametrization map are linear and the face tangents are constant vectors.

	)

static

Computes constant normal vectors to sides of 2D or 3D reference cells.

A side is defined as a subcell of dimension one less than that of its parent cell. Therefore, sides of 2D cells are 1-subcells (edges) and sides of 3D cells are 2-subcells (faces).

Returns rank-1 array with dimension (D), D = 2 or 3 such that

${refSideNormal}(*) = \hat{\bf n}_i = \left\{\begin{array}{rl} \displaystyle \left({\partial\hat{\Phi}_i(t)\over\partial t}\right)^{\perp} & \mbox{for 2D parent cells} \\[2ex] \displaystyle {\partial\hat{\Phi}_{i}\over\partial u} \times {\partial\hat{\Phi}_{i}\over\partial v} & \mbox{for 3D parent cells} \end{array}\right.$

where $(u_1,u_2)^\perp = (u_2, -u_1)$ , and $\hat{\Phi}_i: R \mapsto \hat{\mathcal S}_i$ is the parametrization map of the specified reference side $\hat{\mathcal S}_i$ given by

$\hat{\Phi}_i(u,v) = \left\{\begin{array}{rl} (\hat{x}(t),\hat{y}(t)) & \mbox{for 2D parent cells} \\[1ex] (\hat{x}(u,v),\hat{y}(u,v),\hat{z}(u,v)) & \mbox{for 3D parent cells} \end{array}\right.$

For sides of 2D cells R=[-1,1] and for sides of 3D cells

$R = \left\{\begin{array}{rl} \{(0,0),(1,0),(0,1)\} & \mbox{if $\hat{\mathcal S}_i$ is Triangle} \\[1ex] [-1,1]\times [-1,1] & \mbox{if $\hat{\mathcal S}_i$ is Quadrilateral} \,. \end{array}\right.$

For 3D cells the length of computed side normals is proportional to side area:

$|\hat{\bf n}_i | = \left\{\begin{array}{rl} 2 \mbox{Area}(\hat{\mathcal F}_i) & \mbox{if $\hat{\mathcal F}_i$ is Triangle} \\[1ex] \mbox{Area}(\hat{\mathcal F}_i) & \mbox{if $\hat{\mathcal F}_i$ is Quadrilateral} \,. \end{array}\right.$

For 2D cells the length of computed side normals is proportional to side length:

$|\hat{\bf n}_i | = {1\over 2} |\hat{\mathcal F}_i |\,.$

Because the sides of all reference cells are always affine images of R , the coordinate functions $\hat{x},\hat{y},\hat{z}$ of the parametrization maps are linear and the side normal is a constant vector.

Remarks

For 3D cells the reference side normal coincides with the face normal computed by Intrepid2::CellTools::getReferenceFaceNormal and these two methods are completely equivalent.
For 2D cells the reference side normal is defined by $\hat{{\bf n}}= \hat{\bf t}^\perp = (t_2,-t_1)$ where $\hat{{\bf t}}=(t_1,t_2)$ is the tangent vector computed by Intrepid2::CellTools::getReferenceEdgeTangent. Therefore, the pair $(\hat{{\bf n}},\hat{{\bf t}})$ is positively oriented.

Computes coordinates of sub-control volumes in each primary cell.

To build the system of equations for the control volume finite element method we need to compute geometric data for integration over control volumes. A control volume is polygon or polyhedron that surrounds a primary cell node and has vertices that include the surrounding primary cells' barycenter, edge midpoints, and face midpoints if in 3-d.

When using element-based assembly of the discrete equations over the primary mesh, a single element will contain a piece of each control volume surrounding each of the primary cell nodes. This piece of control volume (sub-control volume) is always a quadrilateral in 2-d and a hexahedron in 3-d.

In 2-d the sub-control volumes are defined in the following way:

   Quadrilateral primary element:

       O________M________O
       |        |        |
       |   3    |   2    |     B = cell barycenter
       |        |        |     O = primary cell nodes
       M________B________M     M = cell edge midpoints
       |        |        |
       |   0    |   1    |     sub-control volumes 0, 1, 2, 3
       |        |        |
       O________M________O


   Triangle primary element:

                O
               / \
              /   \             B = cell barycenter
             /     \            O = primary cell nodes
            M   2   M           M = cell edge midpoints
           / \     / \
          /   \ B /   \         sub-control volumes 0, 1, 2
         /      |      \
        /   0   |   1   \
       O________M________O

In 3-d the sub-control volumes are defined by the primary cell face centers and edge midpoints. The eight sub-control volumes for a hexahedron are shown below:

         O__________E__________O
        /|         /|         /|
       E_|________F_|________E |
      /| |       /| |       /| |
     O_|_|______E_|_|______O | |      O = primary cell nodes
     | | E------|-|-F------|-|-E      B = cell barycenter
     | |/|      | |/|      | |/|      F = cell face centers
     | F-|------|-B-|------|-F |      E = cell edge midpoints
     |/| |      |/| |      |/| |
     E_|_|______F_|_|______E | |
     | | O------|-|-E------|-|-O

     | E--------|-F--------|-E

subCVCoords	[out] - array containing sub-control volume coordinates

Computes F, the reference-to-physical frame map.

There are 2 use cases:

Applies $F_{c}$ for all cells in a cell workset to a single point set stored in a rank-2 (P,D) array;
Applies $F_{c}$ for all cells in a cell workset to multiple point sets having the same number of points, indexed by cell ordinal, and stored in a rank-3 (C,P,D) array;

For a single point set in a rank-2 array (P,D) returns a rank-3 (C,P,D) array such that

$\mbox{physPoints}(c,p,d) = \Big(F_c(\mbox{refPoint}(p,*)) \Big)_d \quad c=0,\ldots, C$

For multiple point sets in a rank-3 (C,P,D) array returns a rank-3 (C,P,D) array such that

$\mbox{physPoints}(c,p,d) = \Big(F_c(\mbox{refPoint}(c,p,*)) \Big)_d \quad c=0,\ldots, C$

This corresponds to mapping multiple sets of reference points to a matching number of physical cells.

Requires pointer to HGrad basis that defines reference to physical cell mapping. See Section Reference-to-physical cell mapping for definition of the mapping function.

Warning: The array refPoints represents an arbitrary set of points in the reference frame that are not required to be in the reference cell corresponding to the specified cell topology. As a result, the images of these points under a given reference-to-physical map are not necessarily contained in the physical cell that is the image of the reference cell under that map. CellTools provides several inclusion tests methods to check whether or not the points are inside a reference cell.

Parameters

physPoints	[out] - rank-3 array with dimensions (C,P,D) with the images of the ref. points
refPoints	[in] - rank-3/2 array with dimensions (C,P,D)/(P,D) with points in reference frame
cellWorkset	[in] - rank-3 array with dimensions (C,N,D) with the nodes of the cell workset
basis	[in] - pointer to HGrad basis used in reference-to-physical cell mapping

Computes F, the reference-to-physical frame map.

There are 2 use cases:

Applies $F_{c}$ for all cells in a cell workset to a single point set stored in a rank-2 (P,D) array;
Applies $F_{c}$ for all cells in a cell workset to multiple point sets having the same number of points, indexed by cell ordinal, and stored in a rank-3 (C,P,D) array;

For a single point set in a rank-2 array (P,D) returns a rank-3 (C,P,D) array such that

$\mbox{physPoints}(c,p,d) = \Big(F_c(\mbox{refPoint}(p,*)) \Big)_d \quad c=0,\ldots, C$

For multiple point sets in a rank-3 (C,P,D) array returns a rank-3 (C,P,D) array such that

$\mbox{physPoints}(c,p,d) = \Big(F_c(\mbox{refPoint}(c,p,*)) \Big)_d \quad c=0,\ldots, C$

This corresponds to mapping multiple sets of reference points to a matching number of physical cells.

Requires cell topology with a reference cell. See Section Reference-to-physical cell mapping for definition of the mapping function. Presently supported cell topologies are

1D: Line<2>
2D: Triangle<3>, Triangle<6>, Quadrilateral<4>, Quadrilateral<9>
3D: Tetrahedron<4>, Tetrahedron<10>, Hexahedron<8>, Hexahedron<27>

Warning: The array refPoints represents an arbitrary set of points in the reference frame that are not required to be in the reference cell corresponding to the specified cell topology. As a result, the images of these points under a given reference-to-physical map are not necessarily contained in the physical cell that is the image of the reference cell under that map. CellTools provides several inclusion tests methods to check whether or not the points are inside a reference cell.

Parameters

physPoints	[out] - rank-3 array with dimensions (C,P,D) with the images of the ref. points
refPoints	[in] - rank-3/2 array with dimensions (C,P,D)/(P,D) with points in reference frame
cellWorkset	[in] - rank-3 array with dimensions (C,N,D) with the nodes of the cell workset
cellTopo	[in] - cell topology of the cells stored in `cellWorkset`

Computes $F^{-1}_{c}$ , the inverse of the reference-to-physical frame map using a default initial guess.

Applies $F^{-1}_{c}$ for all cells in a cell workset to multiple point sets having the same number of points, indexed by cell ordinal, and stored in a rank-3 (C,P,D) array. Returns a rank-3 (C,P,D) array such that

$\mbox{refPoints}(c,p,d) = \Big(F^{-1}_c(physPoint(c,p,*)) \Big)_d$

3D: Tetrahedron<4>, Tetrahedron<10>, Hexahedron<8>, Hexahedron<27>

Warning

Computation of the inverse map in this method uses default selection of the initial guess based on cell topology:

Line topologies: line center (0)
Triangle topologies: the point (1/3, 1/3)
Quadrilateral topologies: the point (0, 0)
Tetrahedron topologies: the point (1/6, 1/6, 1/6)
Hexahedron topologies: the point (0, 0, 0)
Wedge topologies: the point (1/2, 1/2, 0) For some cells with extended topologies, these initial guesses may not be good enough for Newton's method to converge in the allotted number of iterations. A version of this method with user-supplied initial guesses is also available.

The array physPoints represents an arbitrary set (or sets) of points in the physical frame that are not required to belong in the physical cell (cells) that define(s) the reference to physical mapping. As a result, the images of these points in the reference frame are not necessarily contained in the reference cell corresponding to the specified cell topology.

Parameters

refPoints	[out] - rank-3 array with dimensions (C,P,D) with the images of the physical points
physPoints	[in] - rank-3 array with dimensions (C,P,D) with points in physical frame
worksetCell	[in] - rank-3 array with dimensions (C,N,D) with the nodes of the cell workset
cellTopo	[in] - cell topology of the cells stored in `cellWorkset`

Computes parameterization maps of 1- and 2-subcells of reference cells.

Applies $\hat{\Phi}_i$ , the parametrization map of a subcell $\hat{\mathcal{S}}_i$ from a given reference cell, to a set of points in the parametrization domain R of $\hat{\mathcal{S}}_i$ . Returns a rank-2 array with dimensions (P,D) where for 1-subcells:

Remarks

Parametrization of 1-subcells is defined for all 2D and 3D cell topologies with reference cells, including special 2D and 3D topologies such as shell and beams.
Parametrization of 2-subcells is defined for all 3D cell topologies with reference cells, including special 3D topologies such as shells.

To map a set of points from a parametrization domain to a physical subcell workset, apply Intrepid2::CellTools::mapToPhysicalFrame to the output of this method. This will effectively apply the parametrization map $\Phi_{c,i} = F_{c}\circ\hat{\Phi}_i$ of each subcell in the workset to paramPoints. Here c is ordinal of a parent cell, relative to subcell workset, and i is subcell ordinal, relative to a reference cell, of the subcell workset. See Section Subcell worksets for definition of subcell workset and Section Parametrization of physical 1- and 2-subcells for definition of parametrization maps.

Parameters

refSubcellPoints	[out] - rank-2 (P,D1) array with images of parameter space points
paramPoints	[in] - rank-2 (P,D2) array with points in 1D or 2D parameter domain
subcellDim	[in] - dimension of the subcell where points are mapped to
subcellOrd	[in] - subcell ordinal
parentCell	[in] - cell topology of the parent cell.

void Intrepid2::CellTools< SpT >::setSubcellParametrization ( )

staticprivate

Defines orientation-preserving parametrizations of reference edges and faces of cell topologies with reference cells.

Given an edge {V0, V1} of some reference cell, its parametrization is a mapping from [-1,1] onto the edge. Parametrization of a triangular face {V0,V1,V2} is mapping from the standard 2-simplex {(0,0,0), (1,0,0), (0,1,0)}, embedded in 3D onto that face. Parametrization of a quadrilateral face {V0,V1,V2,V3} is mapping from the standard 2-cube {(-1,-1,0),(1,-1,0),(1,1,0),(-1,1,0)}, embedded in 3D, onto that face.

This method computes the coefficients of edge and face parametrization maps. All mappings are affine and orientation-preserving, i.e., they preserve the tangent and normal directions implied by the vertex order of the edge or the face relative to the reference cell:

the tangent on [-1,1] from -1 in the direction of 1 is mapped to a tangent on edge {V0,V1} from V0 in the direction of V1 (the forward direction of the edge determined by its start and end vertices)

the normal in the direction of (0,0,1) to the standard 2-simplex {(0,0,0),(1,0,0),(0,1,0)} and the standard 2-cube {(-1,-1,0),(1,-1,0),(1,1,0),(-1,1,0)} is mapped to a normal on {V0,V1,V2} and {V0,V1,V2,V3}, determined according to the right-hand rule (see http://mathworld.wolfram.com/Right-HandRule.html for definition of right-hand rule and Section Section sec_cell_topology_subcell_map for further details).

Because faces of all reference cells supported in Intrepid are affine images of either the standard 2-simplex or the standard 2-cube, the coordinate functions of the respective parmetrization maps are linear polynomials in the parameter variables (u,v), i.e., they are of the form F_i(u,v)=C_0(i)+C_1(i)u+C_2(i)v; 0<=i<3 (face parametrizations are supported only for 3D cells, thus parametrization maps have 3 coordinate functions). As a result, application of these maps is independent of the face type which is convenient for cells such as Wedge or Pyramid that have both types of faces. Also, coefficients of coordinate functions for all faces can be stored together in the same array.
