Detailed Description

template<typename IndexT, typename RealT, typename IntT, unsigned int dim>
class comma::ARMaxBaryDistanceOverRadius< IndexT, RealT, IntT, dim >

ARComputer. Here, AR is the ratio of the maximum over minimum distance of the cell centers from the barycenter (computed as weighted average of centers). If a cell is totally internal, it won't be included in the computations.

Template Parameters

IndexT	type used for indices
RealT	type used for features
IntT	type used for integers (e.g., number of cells, faces,...)
dim	dimension of the problem (e.g., 1-, 2-, 3D,...)

inlineoverridevirtual

Computes features of the CC obtained by adding a given fine cell. The features are Aspect-Ratio, number of face shared with other cells already agglomerated (Current coarse cell means without i_fc) and those of CellFeatures.

Parameters

[in]	i_fc	Index of the fine cell to add to the coarse cell
[in]	cc_feats	Features of the current coarse cell
[in]	fc_of_cc	Index of the fine cells already agglomerated in the coarse cell
[out]	shared_faces	Number of faces shared by the fine cell with the current coarse cell
[out]	aspect_ratio	Aspect-Ratio of the (final) coarse cell
[out]	new_feats	Features of the (final) coarse cell

Note: The returned AR might not exactly the above-mentioned ration but a similar one where numerator and denominator are raised to certain powers (instead of their roots) as to ensure non-dimensionality
