[Dune-devel] Container to associate a value to each sub-entity of the reference-element

[Simon Praetorius]

Hi everyone,

maybe you can give me a hint. I want to associate to each vertex, edge, 
face, volume of a given reference element (geometry type) a value, 
typically just an integer. Ideally, this container should have a static 
size, depending on the geometry type. Also, I would like to specify 
(statically) how many values to store per codimension, e.g. 
max(dim-codim,1). I could manually implement the offset in a larger 
container using reference element size functions and the sub-entity 
index+codim - a bit similar to a mcmgmapper. The goal is, to have this 
container as compact as possible, since I might need to store one for 
each element in the grid. Is there already something like that available 
in some module, or do I have to do the implementation myself?

The application of this is the improvement of the implementation of 
Lobatto shape functions with the possibility to have a different 
polynomial order on each sub-entity of an element. This is already 
implemented, but the data-structure is not so nice and not generic.

Best,
Simon
