Template Parameters

IndexT	type used for indices
RealT	type used for features
IntT	type used for integers (e.g., number of cells, faces,...)

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

Implements comma::ARComputer< IndexT, RealT, IntT >.
