- The Doxygen style files are now automatically generated from
the sources in dune-common/dune-web. If present, you should remove the
following files from your repository:
doc/doxygen/doxy-footer.* doc/doxygen/doxy-header.* doc/doxygen/dune-doxy.css
- The wml based html generation does now use the layout files
from dune-common. If present, you should remove the
following files from your module:
doc/.wmlrc doc/layout/*
If you remove the layout directory remember to update
the configure.ac and doc/Makefile.am accordingly.
- It is now possible to do out-of-source builds. For this, pass the option
--build-dir to the configure command.
- The dunecontrol program now has an option --resume which allows
to continue an interupted build run in the first unbuild module. During debugging,
this can decrease your build time considerably. Nice!
- The file bitfield.hh, already deprecated in 1.2, has been removed.
Use bitsetvector.hh or std::vector<bool> instead.
- The file stack.hh and class Stack, already deprecated in 1.2,
have been removed. Please use std::stack instead.
- The class DoubleLinkedList, already deprecated in 1.2,
has been removed. Please use std::list instead.
- The file fixedarray.hh has been renamed to array.hh. That way
the file has the same name as the class it contains. The old file is still there
for backward compatibility.
- The type trait EnableIf has been removed. Please use enable_if instead.
- A new smart pointer implementation shared_ptr (in shared_ptr.hh)
has been added, which will replace SmartPointer. The new class reimplements
the stl shared_ptr.
Beware of the following differences when transitioning from SmartPointer
to shared_ptr:
- the type SmartPointer::MemberType becomes shared_ptr::element_type,
- the method SmartPointer::count() becomes shared_ptr::use_count(),
- The default constructor of SmartPointer allocates an
element, and hence returns a dereferenceable pointer.
Default-constructing a shared_ptr instead creates a pointer pointing to NULL.
Hence, if you rely on the SmartPointer default constructor allocating
memory, THIS CHANGE WILL BREAK YOUR CODE!
- The class CompileTimeChecker, already deprecated in 1.2,
has been removed. Please use dune_static_assert instead.
- The header dune/common/helpertemplates.hh and with
it the classes Derived_from, Can_copy, Can_compare,
Can_multiply are deprecated and will be removed in one
of the following releases
- You can now import grids and boundary description from
gmsh. Gmsh is an open source grid generator and CAD engine.
Gmsh reading is supported for all grid that implement the GridFactory.
- Considerable progress has been made on the parallel features of UGGrid.
Special thanks go to Andreas Lauser for this. The following things should
be working now.
- Static load balancing
- Level iterators for all partition types
- Communication for vertex data with constant and variable data size
per vertex (for the interfaces InteriorBorder_All and InteriorBorder_InteriorBorder)
- CollectiveCommunication
- The GlobalIdSet
- The IndexSet classes now have a method subIndex where the codimension of the
subentity can be given at run-time. Previously the codimension had to be a static
parameter. The same holds for the subId method in IdSet, and the
map methods in the various mapper classes.
- The geometry class now has a method jacobianTransposed that
returns the transposed of the Jacobian (i.e., tangential vectors are in the
matrix rows).
- The methods intersectionGlobal, intersectionSelfLocal
and intersectionNeighborLocal on the intersection have been
renamed to geometry, geometryInInside and
geometryInOutside.
-
We introduced a new numbering of the subentities of the reference
elements. The reason is that the new numbering is more consistent and
generalizes more easily to higher dimensions.
Warning: This change may affect your code in subtle ways if you
depend on a particular numbering!
We have assembled a
transition page
with the technical details.
- The methods numberInSelf and numberInNeighbor have been
renamed to indexInInside and indexInOutside, respectively. The meaning
of the return value has changed; now it returns the index with respect to
the generic reference element.
- The methods overlapSize and ghostSize are now available on grid views.
- A new grid implementation, the GeometryGrid, has been added.
It wraps any other DUNE grid and replaces the geometry by a generic one.
It can, for example, be used to transform a 2d Cartesian grid into a
helix. Have a look a the
documentation
for more information.
- Intersections with the domain boundary now provide a boundary segment
index, which is unique within the macro grid.
Children of boundary segments inherit this index from their father.
The index starts at zero is consecutive and the maximum number is returned
by the method numBoundarySegments on the grid.
- A few new methods have been added to the interface (see the documentation for
details):
- Entity::hasFather()
- Geometry::center()
- Intersection::centerUnitOuterNormal()
- The GridFactory class has been extended to include methods
which map a given entity (codimension equal to zero or dimension)
to the order in which it was inserted. This makes it possible to
easily attach data to a dune grid after creation through the grid factory.
- The --with-grid-type, --with-grid-dim, and --with-world-dim
flags have been removed from the dunecontrol process. The required CXXFLAGS
for using gridtype.hh are now always available. The consequence
is that no default can be prescibed during the build process and also no
default is set in the gridtype.hh header. Thus the GRIDTYPE and
GRIDDIM variables have to be set either in Makefile.am or during the
call to make. For programms using gridtype.hh, which are made during the build process,
these variables have to be set in Makefile.am. As before WORLDDIM
defaults to GRIDDIM.
- The method Geometry::checkInside has been deprecated. The same functionality
is now available from the GenericReferenceElements.
- The dimworld template parameter has been removed from YaspGrid. It was there for historical reasons only and had already been deprecated in the 1.2 release.
- The class IntersectionGetter has been removed. With the new GridView
mechanism it is not necessary anymore.
- The IndexSet classes do not provide iterators over the grid any more. This feature
had been deprecated in 1.2. Now it is gone for good.
- In 1.2, several methods and exported types of the IntersectionIterator class have been deprecated there
and moved to the Intersection class. These methods have now been removed from
IntersectionIterator.
- The method Grid::name has been deprecated.
- Dune violates strict-aliasing
You have to compile Dune will the the option "--no-strict-aliasing".
Newer versions of g++ make more use of strict aliasing
rules. If you don't use the "--no-strict-aliasing" option, you will
receive many warnings, and you might even observe undesired results and
unreproducible errors.
But we are not alone with this problem. Several software projects
intentionally violate strict-aliasing. For example, Python 2.x did so
to implement reference counting
(
http://mail.python.org/pipermail/python-dev/2003-July/036898.html). The
Linux kernel does this because strict aliasing causes problems with
optimization of inlined code
(
http://lkml.org/lkml/2003/2/26/158).
