fields on unstructured meshes

[Toon Knapen]

The documentation of pooma 2.3 indicates that one of the next releases will 
contain unstructured meshes. I guess it's not yet for 2.4 since I can't find 
them in the CVS.

But I don't see how the Field concept will be extended to unstructured 
meshes.  A field currently supports Array-like indexing (e.g. 2 indices for 
2-dimensional meshes). But on unstructured meshes, the elements need be 
numbered using some numbering scheme that is not purely based on the position 
of the element. But what happens with the Array-like indexing in this case ?


I'm also curious why you decided to use the dimension (of the problem) as a 
template parameter . As a consequence, you need different executables to 
simulate input-files describing a 2D and a 3D problem. But I guess the 
decision is based on the performance that can be gained by fixing the 
dimension ?
