Updates for ensight writing See merge request !570
-
Mark OLESEN authored
- since ensight format is always float and also always written component-wise, perform the double -> float narrowing when extracting the components. This reduces the amount of data transferred between processors. ENH: avoid vtk/ensight parallel communication of empty messages - since ensight writes by element type (eg, tet, hex, polyhedral) the individual written field sections will tend to be relatively sparse. Skip zero-size messages, which should help reduce some of the synchronization bottlenecks. ENH: use 'data chunking' when writing ensight files in parallel - since ensight fields are written on a per-element basis, the corresponding segment can become rather sparsely distributed. With 'data chunking', we attempt to get as many send/recv messages in before flushing the buffer for writing. This should make the sequential send/recv less affected by the IO time. ENH: allow use of an external buffer when writing ensight components STYLE: remove last vestiges of autoPtr<ensightFile> for output routines

- with ATOMIC, an intermediary file is created - eg, (fileAbc~tmp~) where all of the output is written to. When the stream goes out of scope, this intermediary file is moved/renamed to the actually output name - eg, (fileAbc~tmp~) -> (fileAbc). This adds some safety if the simulation crashes while writing the file, since it will the partial (corrupt) file will be left behind as (fileAbc~tmp~) and not as (fileAbc), which means it will will be treated as a backup file and not loaded again on restart. ENH: provided enumeration for APPEND/NON_APPEND - clearer than using bool (with comments). Since append mode is primarily only used by masterOFstream etc this change is unlikely to affect user coding. ENH: use file atomic for ensight file creation - avoids corrupt (truncated) files being referenced by the ensight case file if the simulation crashes while writing the ensight file.

- eg, for partially incomplete systems (without libz devel header) ENH: clearer binding of dummy Pstream in OpenFOAM/Make/options - link of dummy stub Pstream now contingent on linking libOpenFOAM as well. This makes the purpose slightly clearer ENH: cleaner option naming/handling in wmake script - allow special purpose -no-openfoam option. Eg, compiling test programs without OpenFOAM and Pstream libraries but using the rest of the wmake system. ENH: add +openmp support into WM_COMPILE_CONTROL (#2633) - this adds compile/link flags for openmp. For single-use, can also use 'wmake -openmp'. If both +openmp and ~openmp are specified in WM_COMPILE_CONTROL the ~openmp will have priority. This is actually done indirectly since ~openmp will set empty COMP_OPENMP, LINK_OPENMP internal variables, which the +openmp then adds to the c++FLAGS and linkexe targets (ie, won't actually add anything). ENH: add +ccache or ccache=... support into WM_COMPILE_CONTROL (#2633) - with the first version (+ccache), simply use ccache from the path without any extra options. - with the second version (ccache=...), can be more specific about what is called. Using "+ccache" is identical to "ccache=ccache", but the later could be used in other ways. For example, ccache=/strange/install/path/ccache ccache=</path/my-tooling --option> Have the choice of unquoted, single or double quoted or '< >' quoted STYLE: relocate FOAM_EXTRA_LDFLAGS in general makefile - removes clutter for different linkers (eg, gold, mold, ldd) making it easier to extend for other linkers. STYLE: protect makefile checks with 'strip' function

- 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 See merge request !563

-
- 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'

COMP: overset: fixes for SPDP, int64
-
- Nov 11, 2022
-
-
Note that there is no support for using GAMG with mass-correction.
-
-
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 See merge request !566
-
- 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.
-
- 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) - combineReduce == combineGather + broadcast - 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)
