- set() was silently deprecated in favour of reset() FEB-2018
since the original additional check for overwriting an existing
pointer was never used. The reset(...) name is more consistent
with unique_ptr, tmp etc.
Now emit deprecations for set().
- use direct test for autoPtr, tmp instead of valid() method.
More consistent with unique_ptr etc.
STYLE: eliminate redundant ptr() use on cloned quantities
- occurs with newer gcc on ubuntu impish (gcc-11.2.0), but may perhaps
actually be related to `-flto=auto` or to the destruction order of
the static variables (race condition?).
Leaving the compat table around for automatic cleanup does not
impact on other lookups (which are nullptr checked anyhow).
- partial revert for 13740de427 (#2158)
MS-MPI does not currently have a MPI_Comm_create_group(),
so keep using MPI_Comm_create() there.
Only affects multi-world simulations.
CONFIG: retain dummy version of libPstream.dll
- retain as libPstream.dll-dummy so that it is available for
manual replacement of the regular libPstream.dll (#2290)
Keep extra copy of libPstream.dll as libPstream.dll-msmpi
(for example) for manual replacement.
- this is now consistent with what the internal
"get(Vol|Surface|Point)Field" methods deliver
(ie, zero-gradient for volume, calculated otherwise).
Still some slight inconsistencies with what the internal
"new(Vol|Surface|Point)Field" methods deliver however.
There they are always "calculated"
Enables particles to interact with mesh faces (decsribed using faceZones).
faceInteraction1
{
type faceInteraction;
faceZones
(
(blockageFaces stick)
// (blockageFaces escape)
// (blockageFaces rebound) // not applicable for this test case (!)
);
dMin 0;
dMax 1;
}
The faceZones entry is a list of (faceZoneName interactionType), where
interaction type is either stick, escape or rebound.
The parcel initial velocity can now be set using the new `velocityType`
entry, taking one of the following options:
- fixedValue : (default) same as earlier versions, requires U0
- patchValue : velocity set to seed patch face value
- zeroGradient : velocity set to seed patch face adjacent cell value
Example usage:
model1
{
type patchInjection;
massTotal 1;
SOI 0;
parcelBasisType mass;
patch cylinder;
duration 10;
parcelsPerSecond 100;
velocityType patchValue;
//velocityType zeroGradient;
//U0 (-10 0 0);
flowRateProfile constant 1;
sizeDistribution
{
type normal;
normalDistribution
{
expectation 1e-3;
variance 1e-4;
minValue 1e-5;
maxValue 2e-3;
}
}
}

ENH: Copying alphatLiquid value to alphatVapour for boiling regimes.
When using correlations for boiling regimes the phases next to the
wall are not relevant to these. Therefore the alphat is copied
accordingly from the alphat for liquid.
Only in the sub-cooling RPI model the partition of heat flux
between vapour and liquid is considered.
Calculates propeller performance and wake field properties.
Controlled by executeControl:
- Propeller performance
- Thrust coefficient, Kt
- Torque coefficient, 10*Kq
- Advance coefficient, J
- Open water efficiency, etaO
- Written to postProcessing/<name>/<time>/propellerPerformance.dat
Controlled by writeControl:
- Wake field text file
- Wake: 1 - UzMean/URef
- Velocity in cylindrical coordinates at xyz locations
- Written to postProcessing/<name>/<time>/wake.dat
- Axial wake field text file
- 1 - Uz/URef at r/R and angle
- Written to postProcessing/<name>/<time>/axialWake.dat
- Velocity surface

Usage
Example of function object specification:
\verbatim
propellerInfo1
{
type propellerInfo;
libs (forces);
writeControl writeTime;
patches ("propeller.*");
URef 5; // Function1 type; 'constant' form shown here
rho rhoInf; // incompressible
rhoInf 1.2;
// Optionally write propeller performance data
writePropellerPerformance yes;
// Propeller data:
// Radius
radius 0.1;
rotationMode specified; // specified | MRF
// rotationMode = specified:
origin (0 -0.1 0);
n 25.15;
axis (0 1 0);
// Optional reference direction for angle (alpha) = 0
alphaAxis (1 0 0);
//// rotationMode = mrf
//// MRF MRFZoneName;
//// (origin, n and axis retrieved from MRF model)
// Optionally write wake text files
// Note: controlled by writeControl
writeWakeFields yes;
// Sample plane (disk) properties
// Note: controlled by writeControl
sampleDisk
{
surfaceWriter vtk;
r1 0.05;
r2 0.2;
nTheta 36;
nRadial 10;
interpolationScheme cellPoint;
errorOnPointNotFound false;
}
}
\endverbatim
Where the entries comprise:
\table
Property | Description | Required | Deflt value
type | Type name: propellerInfo | yes |
log | Write to standard output | no | no
patches | Patches included in the forces calculation | yes |
p | Pressure field name | no | p
U | Velocity field name | no | U
rho | Density field name | no | rho
URef | Reference velocity | yes |
rotationMode | Rotation mode (see below) | yes |
origin | Sample disk centre | no* |
n | Revolutions per second | no* |
axis | Propeller axis | no* |
alphaAxis | Axis that defines alpha=0 dir | no |
MRF | Name of MRF zone | no* |
originOffset | Origin offset for MRF mode | no | (0 0 0)
writePropellerPerformance| Write propeller performance text file | yes |
writeWakeFields | Write wake field text files | yes |
surfaceWriter | Sample disk surface writer | no* |
r1 | Sample disk inner radius | no | 0
r2 | Sample disk outer radius | no* |
nTheta | Divisions in theta direction | no* |
nRadial | Divisions in radial direction | no* |
interpolationScheme | Sampling interpolation scheme | no* | cell
\endtable
Note
- URef is a scalar Function1 type, i.e. supports constant, table, lookup values
- rotationMode is used to set the origin, axis and revolutions per second
- if set to 'specified' all 3 entries are required
- note: origin is the sample disk origin
- if set to 'MRF' only the MRF entry is required
- to move the sample disk away from the MRF origin, use the originOffset
- if writePropellerPerformance is set to on|true:
- propellerPerformance text file will be written
- if writeWakeFields is set to on|true:
- wake and axialWake text files will be written
- if the surfaceWriter entry is set, the sample disk surface will be written
- extents set according to the r1 and r2 entries
- discretised according to the nTheta and nRadial entries
