Detailed Description

A ReferenceCell contains the data and methods that are common to all cells of a given geometry type. The ReferenceCell class itself is a handle to a ReferenceCellBase, from which geometry-specific subtypes are derived. ReferenceCell provides several types of service: mapping between physical and reference coordinates, and identification of facets
