Computes the heat transfer coefficient [W/m2/K] using a run-time
selectable model:
- ReynoldsAnalogy
- fixedReferenceTemperature
- localReferenceTemperature
NOTE: The radiative flux (qr) is positive when the heat flux is going into the wall,
this is oposite the the he flux which is positive going out of the wall.
- 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)
When specifying the averaging data, a new `windowType` option is
available, taking the values:
- none: no windowing
- approximate: past functionality (v1706 and earlier)
- exact: exact moving average - will store and write (for restart) all
fields in the window
- Arrhenius viscocity model for incompressible viscocity.
- energyTransport FO for incompressible single and multiple phase
flows and viscousDissipation fvOption source.

- Tutorial to show viscousDissipation:

Note: performs its own tracking and does not rely on the base
particle::trackXXX functions, and uses a local particle position.
Look to update to barycentric tracking in the future.
old "positions" file form
The change to barycentric-based tracking changed the contents of the
cloud "positions" file to a new format comprising the barycentric
co-ordinates and other cell position-based info. This broke
backwards compatibility, providing no option to restart old cases
(v1706 and earlier), and caused difficulties for dependent code, e.g.
for post-processing utilities that could only infer the contents only
after reading.
The barycentric position info is now written to a file called
"coordinates" with provision to restart old cases for which only the
"positions" file is available. Related utilities, e.g. for parallel
running and data conversion have been updated to be able to support both
file types.
To write the "positions" file by default, use set the following option
in the InfoSwitches section of the controlDict:
writeLagrangianPositions 1;
A lot of methods were taking argument data which could be referenced or
generated from the parcel class at little or no additional cost. This
was confusing and generated the possibility of inconsistent data states.
Tracking data classes are no longer templated on the derived cloud type.
The advantage of this is that they can now be passed to sub models. This
should allow continuous phase data to be removed from the parcel
classes. The disadvantage is that every function which once took a
templated TrackData argument now needs an additional TrackCloudType
argument in order to perform the necessary down-casting.
- disable automatically upgrading copyrights in files since changes to
not automatically imply a change in copyright. Eg, fixing a typo in
comments, or changing a variable from 'loopI' to 'loopi' etc.
Calculates the acoustic pressure based on Curle's analogy.
Curle's analogy is implemented as:
\f[
p' = 4 \frac{\pi}{c_0}\frac{\vec d}{|\vec d|^2}\frac{d(F)}{d(t)}
\f]
where
p' | Curle's acoustic pressure [Pa] or [Pa (m3/rho)]
c_0 | Reference speed of sound [m/s]
\vec d | Distance vector to observer locations [m]
F | Force [N] or [N (m3/rho)]
- simply removing the lock file on termination provides insufficient
information for the external application to know if it should take
over again or if OpenFOAM has terminated. Instead the "status=done"
content is now used by default.
