- was found to cause issues (snappyHexMesh specifically)
  on Fugaku. Reported by @Azami

- consistent with sumOp

ENH: globalIndex with gatherNonLocal tag, and use leading dispatch tags

- useful for gather/write where the master data can be written
 separately.  Leading vs trailing dispatch tags for more similarity to
 other C++ conventions.

ENH: functionObjects: refactor and extend histogram

- new submodels:
  - 'equalBinWidth': groups data into bins of equal widths (previous behaviour)
  - 'unequalBinWidth': groups data into bins of unequal widths

- output files per time-step are replaced with a single output file

- silently deprecates the input entries: 'setFormat' and 'formatOptions'

overset modifications: allow overset pacthes overlap, allow fringe faces walk, mass conservation update

COMP: overset: fixes for SPDP, int64

mattijs authored 2 years ago and Kutalmış Berçin committed 2 years ago

Note that there is no support for using GAMG with mass-correction.

sergio authored 3 years ago and Kutalmış Berçin committed 2 years ago

The improvements include:

- Allowing overset patches to be displaced outside background domain.
  - The approach does not support overlapping of multiple inset meshes
    on top of background domain.
- Allowing fringe faces to walk away from hole cells in background domain.
  - The approach was not extensibly tested with overlapping patches.
- Improving mass conservation.
- Various experimental entries are removed: massFluxInterpolation, ddtCorr.
- New entries:
  - oversetAdjustPhi: adds a flux correction outside the pressure equation.
  - massCorrection: adds an implicit correction.

More consistent use of combineReduce, simpler and/or reductions

- replaced ad hoc handling of formatOptions with coordSetWriter and
  surfaceWriter helpers.

  Accompanying this change, it is now possible to specify "default"
  settings to be inherited, format-specific settings and have a
  similar layering with surface-specific overrides.

- snappyHexMesh now conforms to setFormats

  Eg,

      formatOptions
      {
          default
          {
              verbose     true;
              format      binary;
          }
          vtk
          {
              precision   10;
          }
     }

     surfaces
     {
         surf1
         {
             ...

             formatOptions
             {
                 ensight
                 {
                     scale   1000;
                 }
             }
         }
     }

- for later reuse with fields (for example)

ENH: use 'scheduled' for surfaceWriter field merging (#2402)

- in tests with merging fields (surfaceWriter), 'scheduled' was
  generally faster than 'nonBlocking' for scalars, minorly faster for
  vectors.
  Thus make 'scheduled' the default for the surfaceWriter but with a
  user-option to adjust as required. Previously simply relied on
  whichever default globalIndex had (currently nonBlocking).

  Reuse globalIndex information from mergedSurf instead of
  globalIndex::gatherOp to avoid an extra MPI call to gather sizes
  each time.

  These changes will not be noticable unless surface sampling is done
  very frequently (eg, every iteration) and with large core counts.

Mark OLESEN authored 2 years ago and Andrew Heather committed 2 years ago

- support globalIndex for points/faces as an output parameter,
  which allows reuse in subsequent field merge operations.

- make pointMergeMap an optional parameter. This information is not
  always required. Eg, if only using gatherAndMerge to combine faces
  but without any point fields.

ENH: make globalIndex() noexcept, add globalIndex::clear() method

  - broadcast           : (replaces scatter)

  - listCombineReduce   == listCombineGather + broadcast
  - mapCombineReduce    == mapCombineGather + broadcast
  - allGatherList       == gatherList + scatterList

  Before settling on a more consistent naming convention,
  some intermediate namings were used in OpenFOAM-v2206:

    - combineReduce       (2206: combineAllGather)
    - listCombineReduce   (2206: listCombineAllGather)
    - mapCombineReduce    (2206: mapCombineAllGather)
