- 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).
- Use ensightCase for case writing.
Rebase ensightPartCells/ensightPartFaces on
ensightCells/ensightFaces routines.
- Greatly reduces code duplication potential source of errors.
- eliminate ensightAsciiStream, ensightBinaryStream, ensightStream in
favour of using ensightFile and ensightGeoFile classes throughout.
- encapsulate mesh-parts sorting with the ensightCells, ensightFaces
class.
- handle of patches/faceZones entirely within ensightMesh for a lighter
interaction with field output. Both faceZones and point fields need
more testing to see if they behave properly for all cases.
- move some output functionality into its own namespace
'ensightOutput', move into a library.
- use the ensightCase class to open new ensight output streams
in the proper sub-directory locations.
- Place common code under OSspecific.
By including "endian.H", either one of WM_BIG_ENDIAN or WM_LITTLE_ENDIAN
will be defined.
Provides inline 32-bit and 64-bit byte swap routines that can be
used/re-used elsewhere.
The inplace memory swaps currently used by the VTK output are left for
the moment pending further cleanup of that code.
- Less looping when detecting lagrangian clouds and their fields.
- Avoid using Time::setTime() and IOobjectList in tight loops.
They both kill performance immensely.
ENH: provide a -noLagrangian option to foamToEnsight and foamToEnsightParts
for even more control.
- The new field needs initialization with a dimensioned<Type> not just
the dimensionSet.
- The new field was also incorrectly being registered, which could
cause issues later.
Old code:
Found 10990 time steps
Search for moving mesh ... no moving mesh detected.
Startup in 329.09 s
Updated:
Found 10990 time steps
Search for moving mesh ... no moving mesh detected.
Startup in 1.6 s
- Cause was checking "polyMesh/points" via an IOobject.
Short-circuit with a check for a polyMesh/ directory first.
Limit the check to the master-node as well to further reduce
load on the file-system.
------------------------------
ENH: improve per-step conversion times for foamToEnsight.
Old code:
Converting 11001 time steps
Time [0] = 0 Wrote in 1.53 s
Time [1] = 1 Wrote in 1.52 s
...
Time [100] = 100 Elapsed time 205.35 s
Updated:
Converting 11001 time steps
Time [0] = 0 Wrote in 1.4 s
Time [1] = 1 Wrote in 0.07 s
...
Time [100] = 100 Elapsed time 42.4 s
- Speedup by hashing test results from the first conversion step
instead of checking each time.
Check data on all nodes to avoid problems with incomplete writes.
------------------------------
BUG: moving mesh detection failed for foamToEnsightParts
- adjusted to agree with updated foamToEnsight
------------------------------
Note:
- foamToEnsightParts (serial) still has about twice the throughput of
foamToEnsight.
- Default is a width of 8 characters, but this can be extended up to 31
characters via the '-width' command-line option.
- Now use a similar structure as foamToEnsightParts for the masking.
This reduces the clutter within the directory, makes it easier to
selectively delete some time steps (using shell commands).
- Added in a "time" information data in each sub-directory to
make it possible to reconstruct the case file with an external
script.
- Conversion of cloud data should now also work in parallel
(may need more testing).
- Support binary output for cloud data.
- Better avoidance of illegal ensight variable names.
But still partially incomplete (due to patch fields).
==================================================
Example of NEW file structure:
EnSight/verticalChannel.case # case name
EnSight/geometry # for non-moving geometry
EnSight/data/ # time-varying data
EnSight/data/00000000/
EnSight/data/00000001/
...
Fields are stored by name within the data/********/ directories:
EnSight/data/00000001/time # human-readable time info
EnSight/data/00000001/U
EnSight/data/00000001/p
...
EnSight/data/00000001/geometry # for moving geometry
Clouds are stored at the next sub-directory level:
EnSight/data/00000001/lagrangian/<cloudName>/positions
EnSight/data/00000001/lagrangian/<cloudName>/U
...
==================================================
The old structure was significantly more cluttered:
EnSight/verticalChannel.case
EnSight/verticalChannel.0000.mesh
EnSight/verticalChannel.0001.p
EnSight/verticalChannel.0001.<cloudName>
EnSight/verticalChannel.0001.<cloudName>.U
==================================================
- 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.

Resolves bug-report http://bugs.openfoam.org/view.php?id=2099
The normal library system() command uses 'fork', which causes
problems on IB+OPENMPI.
STYLE: add Foam:: qualifier to system calls to make them easier to spot.
Replaced the 'postProcess' argument to the 'write' and 'execute'
functions with the single static member 'postProcess' in the
functionObject base-class.
Generally fields and objects are selected using the 'field[s]' and
'object[s]' keywords but this was not consistent between all
functionObject, fvOptions etc. and now fixed by applying the following
renaming:
fieldName -> field
fieldNames -> fields
objectName -> object
objectNames -> objects
the equivalent functionality is provided by the writeRegisteredObject
functionObject in a MUCH simpler, easier and extensible manner.
functionObject: Removed the now redundant 'timeSet' function.
This changes simplifies the specification of functionObjects in
controlDict and is consistent with the 'libs' option in controlDict to
load special solver libraries.
Support for the old 'functionObjectLibs' name is supported for backward compatibility.
- Avoids the need for the 'OutputFilterFunctionObject' wrapper
- Time-control for execution and writing is now provided by the
'timeControlFunctionObject' which instantiates the processing
'functionObject' and controls its operation.
- Alternative time-control functionObjects can now be written and
selected at run-time without the need to compile wrapped version of
EVERY existing functionObject which would have been required in the
old structure.
- The separation of 'execute' and 'write' functions is now formalized in the
'functionObject' base-class and all derived classes implement the
two functions.
- Unnecessary implementations of functions with appropriate defaults
in the 'functionObject' base-class have been removed reducing
clutter and simplifying implementation of new functionObjects.
- The 'coded' 'functionObject' has also been updated, simplified and tested.
- Further simplification is now possible by creating some general
intermediate classes derived from 'functionObject'.
splitMeshRegions: handle flipping of faces for surface fields
subsetMesh: subset dimensionedFields
decomposePar: use run-time selection of decomposition constraints. Used to
keep cells on particular processors. See the decomposeParDict in
$FOAM_UTILITIES/parallel/decomposePar:
- preserveBaffles: keep baffle faces on same processor
- preserveFaceZones: keep faceZones owner and neighbour on same processor
- preservePatches: keep owner and neighbour on same processor. Note: not
suitable for cyclicAMI since these are not coupled on the patch level
- singleProcessorFaceSets: keep complete faceSet on a single processor
- refinementHistory: keep cells originating from a single cell on the
same processor.
decomposePar: clean up decomposition of refinement data from snappyHexMesh
reconstructPar: reconstruct refinement data (refineHexMesh, snappyHexMesh)
reconstructParMesh: reconstruct refinement data (refineHexMesh, snappyHexMesh)
redistributePar:
- corrected mapping surfaceFields
- adding processor patches in order consistent with decomposePar
argList: check that slaves are running same version as master
fvMeshSubset: move to dynamicMesh library
fvMeshDistribute:
- support for mapping dimensionedFields
- corrected mapping of surfaceFields
parallel routines: allow parallel running on single processor
Field: support for
- distributed mapping
- mapping with flipping
mapDistribute: support for flipping
AMIInterpolation: avoid constructing localPoints
to have the prefix 'write' rather than 'output'
So outputTime() -> writeTime()
but 'outputTime()' is still supported for backward-compatibility.
Also removed the redundant secondary-writing functionality from Time
which has been superseded by the 'writeRegisteredObject' functionObject.
for consistency with the time controls in controlDict and to avoid
unnecessary confusion. All code and tutorials have been updated.
The old names 'outputControl' and 'outputInterval' are but supported for
backward compatibility but deprecated.
Description
This functionObject writes objects registered to the database in VTK format
using the foamToVTK library.
Currently only the writing of the cell-values of volFields is supported but
support for other field types, patch fields, Lagrangian data etc. will be
added.
Example of function object specification:
\verbatim
writeVTK1
{
type writeVTK;
functionObjectLibs ("libIOFunctionObjects.so");
...
objectNames (obj1 obj2);
}
\endverbatim
