document sementics of codim parameter for IndexSet::subIndex (!97) · Merge requests · Core Modules / dune-grid

Martin Nolte requested to merge feature/document-codim-parameter into master Oct 17, 2016

If an entity of codimension cc > 0 is passed into IndexSet::subIndex, what is the semantics of the 'codim' parameter? In DUNE, codimensions are always with respect to the grid dimension (see method subEntity of reference element).

This patch clearly states that codim is to be understood with respect to the grid dimension.
