- include amount of free system memory in profiling, which can give an
indication of when swapping is about to start
- profilingSummary utility to collect profiling from parallel
calculations. Collects profiling information from processor
directories and summarize the time spent and number of calls as (max
avg min) values.
- waitForSlave now return a Time::stopAtControls enumeration:
unknown: when lockfile has no specially recognized content.
endTime: when lockfile contains "status=done"
writeNow: when lockfile contains "action=writeNow"
nextWrite: when lockfile contains "action=nextWrite"
noWriteNow: when lockfile contains "action=noWriteNow"
These values can be used by the caller to terminate the master
(OpenFOAM) as desired in response to information placed there by the
slave process.
- expose the names of write and stopAt controls for reuse elsewhere and
provide a stopAtControls enum for 'unknown'
- track the requested number of sub-cycles (was previously a bool)
- the readList<T>(Istream&) function was introduced to handle command
-options with either a single or a list value, but was also used for
the #remove dictionary directive. However, the parsing was fragile
if the list did not start with a '('.
Now handle command-line arg/option list directly (via ITstream)
and #remove with special-purpose reading of a string or word list.
This removes ambiguity and reduces potential future problems.
STYLE: use ITstream instead of IStringStream for command-line lookups
- parses directly to a tokenList without a string copy.
- unknown options or missing option values now emit a shorter message
without the entire usage. This makes it easier to identify the errors
and is better aligned with the behaviour of GNU system tools.
====
$ simpleFoam -case
Using: OpenFOAM-plus (see www.OpenFOAM.com)
Build: plus-01234
Error: option '-case' requires an argument
See 'simpleFoam -help' for usage
====
- provide for reduced (-help) and full (-help-full) usage information.
In many cases the reduced usage provided sufficient and easier
to find the information.
- make -srcDoc an alias for -doc-source
- no warnings about option aliases for future dates.
- split now optionally retains empty substrings.
Added split on fixed field width.
- Foam::name() now formats directly into string buffer, which a
removes one layer of copying and also avoids using a non-constexpr
in the temporary.
STYLE: explicit type narrowing on zero-padded output for ensight
- allows (for example) splitting a user string on whitespace and
passing this to system as a list of arguments, thus bypassing any
implicit use of 'sh'.
- system() with optional background, for spawning processes.
- this makes them applicable to Foam::string, Foam::word etc
ENH: improvements to CStringList
- add strings() sublist variant which can be useful when handling
command arguments separately
- add construct from SubStrings.
- in rare cases we may wish to have command-line arguments that are
non-mandatory. This can now be reflected in the usage output, provided
that the argList::nonMandatoryArgs() has been used.
- added setRootCaseNonMandatoryArgs.H that applies the
argList::nonMandatoryArgs() settings and otherwise performs largely
as per setRootCase.H, except that the check for mandatory arguments
is deferred to later user code.
- constructor for empty cell/face/point Zones, with contents to be
transferred in later.
- ZoneMesh::operator(const word&) to return existing zone or a new empty one.
- this provides a better typesafe means of locating predefined cell
models than relying on strings. The lookup is now ptr() or ref()
directly. The lookup functions behave like on-demand singletons when
loading "etc/cellModels".
Functionality is now located entirely in cellModel but a forwarding
version of cellModeller is provided for API (but not ABI) compatibility
with older existing user code.
STYLE: use constexpr for cellMatcher constants
- warn or fatal if Pstream::init or Pstream::exit are called multiple
times.
- additional Pstream::initNull method as failsafe to initialize MPI
when the underlying OpenFOAM process is not running in parallel but
the application still needs MPI.
- Pstream::exit() can now also be called without having used MPI::init(),
which means it can be used to cleanup serial process or for
applications that used the special purpose Pstream::initNull()
mechanism.
- the dictionary-driven variant of stitchMesh allows sequential
application of 'stitch' operation with requiring intermediate
writing to disk.
- Without arguments:
* stitchMesh uses a system/stitchMeshDict or -dict dict
- With arguments:
* master/slave patches specified on the command-line as in previous
versions.
Within decomposeParDict, it is now possible to specify a different
decomposition method, methods coefficients or number of subdomains
for each region individually.
The top-level numberOfSubdomains remains mandatory, since this
specifies the number of domains for the entire simulation.
The individual regions may use the same number or fewer domains.
Any optional method coefficients can be specified in a general
"coeffs" entry or a method-specific one, eg "metisCoeffs".
For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
is used, and is also mandatory.
----
ENH: shortcut specification for multiLevel.
In addition to the longer dictionary form, it is also possible to
use a shorter notation for multiLevel decomposition when the same
decomposition method applies to each level.
