Computation of , the inverse of the reference-to-physical frame map.
Applies for a cell workset to a single point (P,D) view. Computes a rank-2 (P,D) view such that
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. Note that the physical point can be in a space with larger dimension, e.g. if mapping a reference quadrilateral into a side in 3D space.
Warning
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
refPoint
[out] - rank-2 view with dimension (refD) with the reference point
physPoint
[in] - rank-2 view with dimension (physD) with the point in physical frame
cellNodes
[in] - rank-2 array with dimensions (N,physD) with the nodes of the cell containing the physical point
Returns
a boolean set to true if the algorithm converged, to false otherise.
