This is the list of changes made on the hp branch; this list will be merged back into the main document listing changes once the hp branch is merged as well. Since the hp branch only exists in the deal.II subdirectory, only this category exists below.
All entries are signed with the names of the author. Regular contributor's names are abbreviated by WB (Wolfgang Bangerth), GK (Guido Kanschat), RH (Ralf Hartmann).
Changed:
Changed FE
to
FECollection
at several places and
also changed depending functions accordingly. Modified the
reserve_space
method of
hpDoFHandler
to work for 2D
DG-problems. In this context the 2D code for
pre_refinement_notification
was
added as well.
(Oliver Kayser-Herold 2003/12/11)
Changed:
Implemented a couple of small modifications to get a first 1D
hp-example running. The Triangulation
class was extended by a method to add
RefinementListener
s, which allow
other classes to be informed about Refinements. This is
needed for the hpDoFHandler
, which
administrates the active_fe_indices
in the hpDoFLevel
s. Once this
was implemented, the other changes were straightforward. For
1D, the only thing which had to be changed for hp was the
reserve_space
method.
Last but not least, for the hp-example the
add
method was added to the
FECollection
. It allows the user to
add new FiniteElements
s to the
the FECollection
.
(Oliver Kayser-Herold 2003/06/01)
Changed: Introduced the DoFHandler
as template parameter in classes DataOutStack
,
DataOutFaces
, DataOut
and
DataOut_DoFData
.
DoFHandler
is used as default
template argument to ensure backward compatibility. Added
an overloaded method reinit
for the
new hpDoFHandler
in class
FEValues
. Modified method
interpolate_boundary_values
in
class VectorTools
to take the
DoFHandler
as template
argument. Probably this method must be changed later, when the real
hpDoFHandler
is implemented. Added
the first implementation of the
hpDoFHandler
which is simply a copy
of the old one. But it should provide a good basis for the new
one. Finally the DoFAccessor
is now
instantiated for the new
hpDoFAccessor
. Overall these changes
now allow the compilation of some of the sample programs with
the new hpDoFAccessor
but obviously
not yet with new functionality.
(Oliver Kayser-Herold 2003/02/18)
Changed: The DoFHandler::n_boundary_dofs
functions have been moved and renamed. They are now
DoFTools::count_boundary_dofs
.
(WB 2003/02/18)
Changed: The DoFLevel
classes has been moved to
a namespace internal
, since they are not
meant for public use.
(WB 2003/02/18)
Changed: Many of the functions in DoFTools
are now templatized to accept both DoFHandler
and hpDoFHandler
objects.
(WB 2003/02/14)
Changed: The TriaDimensionInfo
and
DoFDimensionInfo
classes that were used to
declare typedefs for the iterators have been moved to a namespace
internal (so as to get them out of the class index in the documentation
-- these classes were not meant for use in applications after all), and
have been renamed to TriaIteratorSelector
and DoFIteratorSelector
, since that is what
they are.
(WB 2003/02/13)
Changed: Due to the demand for different DoFHandler
classes (mainly for the planned
hp-DoFHandler) the DoFHandler has been introduced as a
template parameter into the DoFAccessor
,
the DoFObjectAccessor
,
and the DoFCellAccessor
classes.
Furthermore the DoFHandler
was
also introduced as template parameter into the
DoFDimensionInfo
class. These changes induced several little changes in a couple
of methods to get the code through the compiler. But no
functionality was affected.
(Oliver Kayser-Herold 2003/01/24)
Changed: There are now overloaded versions of the FEValues::reinit
function (and likewise in the
FEFaceValues
and FESubFaceValues
classes) that either take a
Triangulation::cell_iterator
or a
DoFHandler::cell_iterator
. That means that
you can compute certain data with only the geometrical information the
former provides, independent of whether degrees of freedom are
associated with this cell or not. However, certain functions of the
FEValues
class will throw an error if you
attempt to use them without DoF data being delivered in the
reinitialization call; these functions need to extract values from
finite element fields, and are mostly the
FEValues::get_function_values/grads/2nd_derivatives
functions.
(WB 2003/01/20)
Changed: The Mapping::transform_real_to_unit_cell
and
Mapping::transform_unit_to_real_cell
now only take a Triangulation::cell_iterator
instead of a DoFHandler::cell_iterator
as
previously. This is also reasonable, since they only need the geometric
information.
(WB 2003/01/20)
Changed: The FiniteElement::fill_fe_*_values
now only take a Triangulation::cell_iterator
instead of a DoFHandler::cell_iterator
as
previously. Likewise for FiniteElementBase::compute_2nd
and FESystem::compute_fill
, and the
Mapping::fill_fe_*_values
functions.
