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 |/ |/ |/ O__________E__________O

Computes F, the reference-to-physical frame map.
There are 2 use cases:
For a single point set in a rank-2 array (P,D) returns a rank-3 (C,P,D) array such that
For multiple point sets in a rank-3 (C,P,D) array returns a rank-3 (C,P,D) array such that
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.
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.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 container with logical dimensions (C,N,D) with the nodes of the cell workset |
