[Dune] Question about Dune-alugrid license

[Oliver Sander]

Salut Christophe,

> We saw that ug grid could be used but it does not match our needs for now since it does not provide codimension-1 entities.

what precisely do you mean by this?  UGGrid does provide codim-1 entities.  It does not provide iteration over these
entities, but that should be relatively easy to implement if you really need it.

Best,
Oliver


> Our idea was the following: rely on Yaspgrid in a first  time, but we were hoping to keep the possibility to use an unstructured grid in the future, and so to minimize the dependence to Yaspgrid as much as possible if we can. We were thinking about alugrid for that.
> 
> I imagine this is still possible but there will be more work to do with ug grid since we would have to implement the missing functionalities, isn't it?
