- erroneous double logic for subset meshes.
The underlying vtk::vtuCells uses a cellMap to map into a global
field, which also allows handling of decomposed polyhedral cells.
If a mesh subset is involved (eg, cellSet, cellZone), then the
set/zone cellMap can be used to ensure that the original number is
properly adjusted. For foamToVTK, the meshSubsetHelper already
does the subsetting and is used when loading fields.
Does not affect ParaView reader module since there we work on the
full field and do the subsetting manually (using the cellMap).
- disable automatically upgrading copyrights in files since changes to
not automatically imply a change in copyright. Eg, fixing a typo in
comments, or changing a variable from 'loopI' to 'loopi' etc.
- This provides a mechanism for moving mesh patches based on external
input (eg, from an external structures solver). The patch points are
influenced by the position and rotation of the lumped points.
BC: lumpedPointDisplacementPointPatchVectorField
Controlling mechanisms:
- externalCoupler
for coordinating the master/slave
- lumpedPointMovement
manages the patch-points motion, but also for extracting forces/moments
- lumpedPointState
represents the positions/rotations of the controlling points
Utils:
- lumpedPointZones
diagnostic for visualizing the correspondence between controlling
points and patch faces
- lumpedPointMovement
Test that the patch motion is as desired without invoking moveMesh.
With the -slave option, return items from a precalculated table
for the lumpedPointDisplacementPointPatchVectorField BC.
- with the xml append format it is possible to write raw binary
(instead of base64), but the writer becomes more complicated.
Either needs two passes to create, or need to allocate a block
of space for the header information (like VTK itself does) and
write later.
* internalWriter
* patchWriter
* surfaceMeshWriter
* lagrangianWriter
Also these special purpose ones:
* foamVtkWriteSurfFields
- this shifts responsibility away from caller to the individual writers
for knowing which file formats are supported and which file ending is
appropriate. When the writer receives the output format request,
it can elect to downgrade or otherwise adjust it to what it can
actually manage (eg, legacy vs xml vs xml-append).
But currently still just with legacy format backends.
- The reader module allows two levels of caching.
The OpenFOAM fvMesh can be cached in memory, for faster loading of
fields. Additionally, the translated VTK geometries are held in a
local cache. The cached VTK geometries should incur no additional
overhead since they use the VTK reference counting for their storage
management.
- this allows filling in the VTK structures without intermediate data
and without sequencial insertion. Should be faster and smaller
than the previous cell-wise insertion methods.
Most importantly, it improves code reuse.
- has the selected values directly and use these lookup names to store
directly into a hash. This replaces several parallel lists of
decomp information etc and makes it easier.
- Use on/off vs longer compressed/uncompressed.
For consistency, replaced yes/no with on/off.
- Avoid the combination of binary/compressed,
which is disallowed and provokes a warning anyhow
- ensure that the string-related classes have consistently similar
matching methods. Use operator()(const std::string) as an entry
point for the match() method, which makes it easier to use for
filters and predicates. In some cases this will also permit using
a HashSet as a match predicate.
regExp
====
- the set method now returns a bool to signal that the requested
pattern was compiled.
wordRe
====
- have separate constructors with the compilation option (was previously
a default parameter). This leaves the single parameter constructor
explicit, but the two parameter version is now non-explicit, which
makes it easier to use when building lists.
- renamed compile-option from REGEX (to REGEXP) for consistency with
with the <regex.h>, <regex> header names etc.
wordRes
====
- renamed from wordReListMatcher -> wordRes. For reduced typing and
since it behaves as an entity only slightly related to its underlying
list nature.
- Provide old name as typedef and include for code transition.
- pass through some list methods into wordRes
hashedWordList
====
- hashedWordList[const word& name] now returns a -1 if the name is is
not found in the list of indices. That has been a pending change
ever since hashedWordList was generalized out of speciesTable
(Oct-2010).
- add operator()(const word& name) for easy use as a predicate
STYLE: adjust parameter names in stringListOps
- reflect if the parameter is being used as a primary matcher, or the
matcher will be derived from the parameter.
For example,
(const char* re), which first creates a regExp
versus (const regExp& matcher) which is used directly.
- less clutter and typing to use the default template parameter when
the key is 'word' anyhow.
- use EdgeMap instead of the longhand HashTable version where
appropriate
e.g.
ramp
{
type quadratic;
start 200;
duration 1.6;
}
but the old format is supported for backward compatibility:
ramp linear;
rampCoeffs
{
start 200;
duration 1.6;
}
- as originally intended years ago, but never actually done.
- use 'foamPvCore' instead of 'vtkPVReaders' to avoid potential name
collisions with any 'vtk*' files and since we may reuse these
functions in other foam-paraview modules (not just readers).
STYLE: use same font size/colour for patch-names as for point-numbers
BUG: repair issue with single time-step
- paraview time-selector returns '0' as the requested time if there is
only one time step. However, if we have skipped the 0/ directory,
this single time step is likely a non-zero value.
- use "-pvMAJ.MIN" suffix for similarity with the paraview convention
- use sentinel file to ensure clean change of intermediate targets
- ensure all library files are being properly removed
- remove old (ParaView-3) files
- Works in 4.4.0, 5.0.1, 5.2.0 etc
STYLE:
- slots now use SM properties directly without a second lookup.
This reduces exposure of the QT elements and simplifies the coding.
- avoid focus borders on the Qt elements
- place the "use Polyhedron" checkbox into a column
- move "Cache Mesh" down in the GUI (an advanced feature and thus
should be less prominent)
- obtain button labels/tooltip directly from the XML content
- although this is not the final desired form, since it uses
individual pqPropertyWidget customizations (ie, ugly layout, too
many bits of code), but is an interesting intermediate solution
that may be useful in other contexts.
- Could be related to interrupted builds.
So if there are any parts of the build that rely on an explicit
'wmakeLnInclude', make sure that the contents are properly updated.
--
ENH: improved feedback from top-level Allwmake
- Report which section (libraries, applications) is being built.
- Provide final summary of date, version, etc, which can be helpful
for later diagnosis or record keeping.
- The -log=XXX option for Allwmake now accepts a directory name
and automatically appends an appropriate log name.
Eg,
./Allwmake -log=logs/ ->> logs/log.linux64GccDPInt32Opt
The default name is built from the value of WM_OPTIONS.
--
BUG: shell not exiting properly in combination with -log option
- the use of 'tee' causes the shell to hang around.
Added an explicit exit to catch this.
--
- Detecting the '-k' (-non-stop) option at the top-level Allwmake, which
may improve robustness.
- Explicit continue-on-error for foamyMesh (as optional component)
- unify format of script messages for better readability
COMP: reduce warnings when building Pstream (old-style casts in openmpi)
- in specific cases it can be useful to suppress searching the instances.
For example, if one only wishes to check if a "points" is available at
the given time instance, without searching backwards through all
times.
- Cannot test if these older reader modules actually build,
owning largely to build issues since with paraview 3.14 (Feb 2012)
and paraview 3.98 (Dec 2012) themselves.
Note: classes are prefixed with 'foamVtk' instead of 'vtk' to avoid potential
conflicts with VTK itself.
foamVtkCore
~~~~~~~~~~~
- General very low-level functionality.
foamVtkPTraits
~~~~~~~~~~~~~~
- Traits type of functionality for VTK
foamVtkOutputOptions
~~~~~~~~~~~~~~~~~~~~
- The various format output options as a class that can be passed to
formatters etc.
foamVtkCells
~~~~~~~~~~~~
- Intended for unifying vtkTopo and PV-Reader code in the future.
- Handles polyhedron decompose internally etc
foamVtkOutput, foamVtkFormatter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Output helpers.
- Selector for individual formatters.
Currently write all scalar data a 'float' (not 'double'). Can
revisit this in the future.
For example, to mesh a sphere with a single block the geometry is defined in the
blockMeshDict as a searchableSurface:
geometry
{
sphere
{
type searchableSphere;
centre (0 0 0);
radius 1;
}
}
The vertices, block topology and curved edges are defined in the usual
way, for example
v 0.5773502;
mv -0.5773502;
a 0.7071067;
ma -0.7071067;
vertices
(
($mv $mv $mv)
( $v $mv $mv)
( $v $v $mv)
($mv $v $mv)
($mv $mv $v)
( $v $mv $v)
( $v $v $v)
($mv $v $v)
);
blocks
(
hex (0 1 2 3 4 5 6 7) (10 10 10) simpleGrading (1 1 1)
);
edges
(
arc 0 1 (0 $ma $ma)
arc 2 3 (0 $a $ma)
arc 6 7 (0 $a $a)
arc 4 5 (0 $ma $a)
arc 0 3 ($ma 0 $ma)
arc 1 2 ($a 0 $ma)
arc 5 6 ($a 0 $a)
arc 4 7 ($ma 0 $a)
arc 0 4 ($ma $ma 0)
arc 1 5 ($a $ma 0)
arc 2 6 ($a $a 0)
arc 3 7 ($ma $a 0)
);
which will produce a mesh in which the block edges conform to the sphere
but the faces of the block lie somewhere between the original cube and
the spherical surface which is a consequence of the edge-based
transfinite interpolation.
Now the projection of the block faces to the geometry specified above
can also be specified:
faces
(
project (0 4 7 3) sphere
project (2 6 5 1) sphere
project (1 5 4 0) sphere
project (3 7 6 2) sphere
project (0 3 2 1) sphere
project (4 5 6 7) sphere
);
which produces a mesh that actually conforms to the sphere.
See OpenFOAM-dev/tutorials/mesh/blockMesh/sphere
This functionality is experimental and will undergo further development
and generalization in the future to support more complex surfaces,
feature edge specification and extraction etc. Please get involved if
you would like to see blockMesh become a more flexible block-structured
mesher.

- There will be triangles rendered inside the mesh (when
surface-rendering), because one of the cell's triangles is defined
as a quadrangle in VTK_WEDGE.
- Therefore, this VTK_WEDGE representation is only used when
decomposing the mesh, otherwise the correct representation is done
by VTK_POLYHEDRON.
- Furthermore, using VTK_PYRAMID gave worse result, because it renders
2 triangles inside the mesh for the collapsed quadrangle, likely due
to mismatch with the adjacent cell's face.
- Using VTK_HEXAHEDRON was not tested in this iteration, given that it
should give even worse results, when compared to using VTK_PYRAMID.
Patch contributed by Bruno Santos
Resolves bug-report http://bugs.openfoam.org/view.php?id=2099
Now the functionality to write single graph files or log files (vs time)
may be used in the creation of any form of functionObject, not just
those relating to a mesh region.
- manifest in some parallel operations.
STYLE: update foamToEnsight, foamToEnsightParts to use C++ initializer_list
- avoid warning message when removing a non-existent directory (ensight output).
