cb4bf9e6b7 BUG: foamToEnsight fails with missing field at time 0 (fixes #473) 2017-05-16 17:28:09 +02:00

7b4680482e ENH: use string endsWith in a few places
fieldName.endsWith("_0")
vs
    fieldName.size() > 2 && fieldName(fieldName.size()-2, 2) == "_0"

784461b2fa ENH: make search of instances in IOobject::typeHeaderOk optional (issue #245)
- 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.

88ca081c8c ENH: reduce startup time for ensight conversion (issue #240).
- 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.

0c168c43fa ENH: improve startup time for foamToEnsight conversion (issue #240).
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.

9de4a75813 ENH: expand data mask for foamToEnsight (issue #231)
- 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

==================================================

e424059208 ENH: glboal file handling: initial commit
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.

605088884e ENH: point merging of internal and patches.
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.

72362de6b1 foamToEnsight* fixes and tweaks
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
