[Dune] Laplace example (Code included)

[Arne Rekdal]

Hello.

I am a Norwegian master student in applied mathematics. I study at  
NTNU in Trondheim. Currently I am working on an implementation of a  
FEM solver for the Laplace equation. This is part of the prestudy for  
my thesis.

I can?t see an example like this on the homepage of DUNE (I know about  
the Grid How-to). Could this be of interest?

I have implemented a solver now, with great help from this mailing  
list. I am aware that some of the solutions are not very elegant. My  
biggest concern is the structure of the implementation. I have also  
question about the Mapper interface; from what I can see, it is not  
possible to create a mapper that only maps the degrees of freedom?

The source code for the solver is included, and any suggestions for  
improvements and answers to the questions I have put in the code will  
be greatly appreciated.


Best regards
Arne Rekdal
