- 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
==================================================
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
These new names are more consistent and logical because:
primitiveField():
primitiveFieldRef():
Provides low-level access to the Field<Type> (primitive field)
without dimension or mesh-consistency checking. This should only be
used in the low-level functions where dimensional consistency is
ensured by careful programming and computational efficiency is
paramount.
internalField():
internalFieldRef():
Provides access to the DimensionedField<Type, GeoMesh> of values on
the internal mesh-type for which the GeometricField is defined and
supports dimension and checking and mesh-consistency checking.
The deprecated non-const tmp functionality is now on the compiler switch
NON_CONST_TMP which can be enabled by adding -DNON_CONST_TMP to EXE_INC
in the Make/options file. However, it is recommended to upgrade all
code to the new safer tmp by using the '.ref()' member function rather
than the non-const '()' dereference operator when non-const access to
the temporary object is required.
Please report any problems on Mantis.

Moved file path handling to regIOobject and made it type specific so
now every object can have its own rules. Examples:
- faceZones are now processor local (and don't search up anymore)
- timeStampMaster is now no longer hardcoded inside IOdictionary
(e.g. uniformDimensionedFields support it as well)
- the distributedTriSurfaceMesh is properly processor-local; no need
for fileModificationChecking manipulation.
- checkMesh has option to write faceSets or (outside of) cellSets as
sampledSurface format. It automatically reconstructs the set on the master
and writes it to the postProcessing folder (as any sampledSurface). E.g.
mpirun -np 6 checkMesh -allTopology -allGeometry -writeSets vtk -parallel
- fixed order writing of symmTensor in Ensight writers
- redistributePar to have almost (complete) functionality of decomposePar+reconstructPar
- low-level distributed Field mapping
- support for mapping surfaceFields (including flipping faces)
- support for decomposing/reconstructing refinement data
Each collocated set of coupled points has a single master assigned to it.
However when doing mergePoints on a patch the master does not have to be
on the patch. So now it returns mesh point labels, not patch point labels.
Uses globalMeshData::mergePoints to topologically merge mesh points.
Also now require all patches on all processors so cleaned up all code for
handling zero-sized patches.
foamToEnsight:
- add -noPatches option
- had incorrect part# when the internalMesh was not output
- case file is always ascii
foamToEnsightParts:
- fixed field selection bug,
no fields were selected when a single time-step was selected
- objectRegistry gets a rename() that also adjusts the dbDir
- cloud reworked to use static variables subInstance and defaultName.
This avoids writing "lagrangian" everywhere
string fixes
- avoid masking of std::string::replace in string.H
- avoid old strstream in PV3FoamReader
- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
'XX.size() <= 0' or for simpler coding.
It also has the same number of characters as '!XX.size()' and /might/ be
more readable
- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
when a simple 'XX.size()' suffices
