Detailed Description

Set of local quantities and connectivities related to a mesh cell.

This is a key structure for all cellwise processes. This structure belongs to one thread and only. This structure used allows one to get a better memory locality. It maps the existing global mesh and other related structures into a more compact one dedicated to a cell. Arrays are allocated to the max number of related entities (e.g. n_max_vbyc or to n_max_ebyc). The cell-wise numbering is based on the c2v, c2e and c2f connectivity.
