Coarse grid creation interface
There will be a well defined interface for the creation of coarse
grids. It will be similar to the interface already implemented for
UGGrid. However, the functionality will be moved into a separate
factory class. File readers will then use this factory.
Oliver Sander will implement a first prototype for UGGrid.
Freiburg will split up the DGF code. The GridPtr class will be
removed, all GridFactories will return a Grid*. The DGFParser
will be updated to use the Factory interface.
Assigned to Oliver Sander and the DGFParser developers.
Index type returned by index sets
The type for the indices returned by index sets will now be
available as a typedef in the class. Existing implementations
will be switched to unsigned int.
Assigned to Oliver Sander.
Polynomial order of geometries
The necessity for geometries to hand out information about
its smoothness properties is generally recognized. However
no good solution has been found. The topic needs further
research.
Postponed
Boundary ID
The boundaryID method will be made available in UGGrid.
Assigned to Oliver Sander.
Keeping EntityPointers small by specifying reference lifetime
The EntityPointer class gets a method compactify(). Calling
this methods suggests to the class to release all nonessential
memory allocated by the class. This allows to store large amounts
of EntityPointers.
Assigned to Carsten Gräser.
Entity vs. EntityPointer
There will be two new methods mark() and getMark() in the grid
class which take an Entity as the argument. The corresponding
methods taking EntityPointers will be deprecated. Also, the
class Entity will get a method pointer() which returns an
EntityPointer to the current Entity.
Assigned to Robert Klöfkorn.
Generic Geometry classes
Generic geometry classes will be made available to simplify
grid implementations.
Assigned to Martin Nolte.
XYZDefault classes
The default classes will be removed successively from the
interface.
Assined to every grid developers.
Make IntersectionIterator a real iterator
The two intersection iterators will be transformed to real
iterators which offers only the iterator functionality and
which can be referenced to yield the actual intersection,
new implemented as a separate class.
Assigned to Christian Engwer.
SubEntities
All grids are now required to implement the subEntity method
for all codimensions. In the short range these entities do
not have to provide geometries.
Assigned to the YaspGrid and UGGrid developers.
Parametrize class with the Traits class
Alltemplate parameters should be changed to the GridTraits,
Redundant information can be removed.
Postponed.
Generic reference elements
Peter documents his implementation for generic cube
reference elements. Freiburg tries to incorporate this into
their generic reference element implementation.
Assigned to Peter Bastian and Martin Nolte.
Save/restore for grids
There will be save/restore facilities in the interface.
Andreas will work out a detailed specification.
Assigned to Andreas Dedner.
Method conforming() on intersection
The class Intersection will get an additional method
conforming(), which returns true iff the intersection is
a complete face for both elements involved.
Assigned to Andreas Dedner.
Thread safety
There will be two new capabilities threadSafe and viewThreadSafe,
which assure overall thread safety and read-only thread safety,
respectively.
Assigned to every grid developer.
Remove GridPart functionality from the index sets
The methods begin() and end() and the corresponding types in
the IndexSets will be marked deprecated and removed eventually.
Assigned to Oliver Sander.
GridView
The grid parts will be renamed to GridViews. All relevant
size/begin/end/intersection/indexset/communicate method will be moved
to them. They lose the method level().
Assigned to Sven Marnach and Oliver Sander.
HierarchicIndexSet/HierarchicGridPart
These will be removed from the dune-grid module.
Assigned to Robert Klöfkorn.
Capability 'hasHangingNodes' and 'IsUnstructured' vs, 'isCartesian'
'hasHangingNodes' and 'IsUnstructured' will be marked
deprecated. 'isCartesian' will replace 'IsUnstructured'
and will have the following semantics:
$T \circ S$where T is a translation and S a scaling operator
ItersectionIterator it; ... int axis = it.numberInSelf()/2;
Separate sparsity structure and entries in BCRSMatrix
Martin Weiser will provide a prototype implementation for
this.
Assigned to Martin Weiser.

Nomen est omen
dune-functions
Containing mappers and discrete functions.
dune-grid-dev-howto
In a first step this will contain an example grid implementation,
which does nothing but wrapping a DUNE grid. This will help
people to get started with their own grid implementations.
Later we plan to have a tutorial on how to implement grids and
a set of successively tighter unit tests.
Heterogeneous Matrix Class
Martin Weiser donates his heterogeneous matrix class to dune-istl. He will get
write access and clean up the code and commit it in the near future.
Assigned to Martin Weiser.
Project Overview
Mario sets up a list of groups, persons, and projects that are known
to use DUNE. Each will get a small description, possibly formalized
in some way. The page 'Publications using DUNE' will be removed.
