ENH: new solvers: overPhaseChangeInterFoam and overCompressibleInterDyMFoam

See merge request Development/openfoam!425

sergio authored 4 years ago and Kutalmış Berçin committed 4 years ago

- overCompressibleInterDyMFoam: Overset solver for two compressible,
non-isothermal, immiscible fluids using a VOF (i.e. volume of fluid)
phase-fraction based interface capturing approach.
- overInterPhaseChangeDyMFoam: Overset solver for two incompressible,
isothermal, immiscible fluids with phase-change (e.g. cavitation) using
VoF (i.e. volume of fluid) phase-fraction based interface capturing approach.
- adds new tutorials:
  - multiphase/overCompressibleInterDyMFoam/compressibleTwoSimpleRotors
  - multiphase/overInterPhaseChangeDyMFoam/twoSimpleRotors

- useful when used in a batch process to trap the exit signal,
  e.g. stop the run when the velocity magnitude exceeds a given
  threshold:

    runTimeControl
    {
        type            runTimeControl;
        libs            ("libutilityFunctionObjects.so");
        nWriteStep      1;

        // Optional end 'action'
        satisfiedAction abort; // end; // setTrigger

        conditions
        {
            maxU
            {
                type            minMax;
                functionObject  MinMax;
                fields          ("max(mag(U))");
                value           1e6;
                mode            maximum;
            }
        }
    }

- adjust sync condition (continuation of 201f117f)

- truncates output file, handles compressed streams

- if the system/decomposeParDict is missing, skip check for matching
  number of processor dirs. This can make job dispatch easier.
  Does not apply if -decomposeParDict was explicitly specified.

STYLE: adjust naming of host/slaves in argList

- ensure that the processor directory cache is consistently available
  by providing appropriate synthesized names. If the expected files
  really do not exist, it will still fail at a later point (but not in
  the caching).

  This addresses cases that have been manually distributed
  (different content on different nodes, but the same root path),
  while still maintaining the readDir on master only for massively
  parallel cases (#1946). It also addresses regular cases with
  gaps in the processor directories.

- new '-ascii' option to write in ASCII format instead of the
  controlDict setting. This can be useful when generating fields that
  should be parsed with other tools, or for visual inspection.

- correct mismatch of option names and lookups

- can use either command-line option "-load-fields" or dictionary
  entry "readFields" to specify field names to be preloaded.

  Essentially the same functionality as with a readFields function
  object but with a lot less typing.

- tutorial examples provided by Ryan Danks <ryan.danks@rwdi.com>
  illustrate using setExpr* utilities to calculate a quantity
  as a post-processing step.

- simplifies local toggling.

- centralize fileModification static variables into IOobject.
  They were previously scattered between IOobject and regIOobject

- additional include "Switch" in expressions

Support for DimensionedFields

ENH: Improvement to overset that allows multiple motion solvers

See merge request Development/openfoam!428

sergio authored 4 years ago and Andrew Heather committed 4 years ago

     to operate with overset

1) Adding zoneMotion to rigidBodyMotion
2) Introducing PID to prescribedRotation restraint
3) Making drivenLinearMotion read total displacement
4) When drivenLinearMotion is used sixDof and rigid-body solvers
   write total displacement

file "meta" information

See merge request Development/openfoam!430

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- currently add to mesh zones to provide a table of contents
  of the zone names that allows downstream consumers quick access to
  the information without needing to parse the entire file.

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- support selective enable/disable of the file banner.

ENH: improve code isolation for decomposedBlockData

- use readBlockEntry/writeBlockEntry to encapsulate the IO handling,
  which ensures more consistency

- new decomposedBlockData::readHeader for chaining into the
  block header information.

- remove unused constructors for decomposedBlockData

ENH: minor cleanup of collated fileOperations

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- improves interface and data consistency.
  Older signatures are still active (via the Foam_IOstream_extras
  define).

- refine internals for IOstreamOption streamFormat, versionNumber

ENH: improve data alignment for IOstream and IOobject

- fit sizeof label/scalar into unsigned char

STYLE: remove dead code

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- read/write lists of character data in binary only.
  This is the only means of preserving data.
  If character data are written as an ASCII list, there is no means of
  determining if spaces or newlines are content or separators.

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- handle binary/contiguous first as being the most obvious, followed
  by increasing complexity of ascii.
  Structure reading and writing routines similarly by introducing a
  readList method to compliment the writeList method.

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- would ideally like the same for tmp, but there is too much existing
  code that uses a multiply operation that would be interpreted as a
  dereference.
