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).
- 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.
- 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.
- 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
==================================================
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.
- remove old VTK_CONVEX_POINT_SET code, since VTK_POLYHEDRON exists
since several years
ENH: improve robustness of paraFoam script
- only check the relevant plugin types,
fallback to native reader if needed/possible.
