Computes a histogram for the distribution of particle diameters
and corresponding number of particles hitting on a given list of patches.
A minimal example by using `constant/reactingCloud1Properties.cloudFunctions`:
```
patchParticleHistogram1
{
// Mandatory entries (unmodifiable)
type patchParticleHistogram;
patches (<patch1> <patch2> ... <patchN>);
nBins 10;
min 0.1;
max 10.0;
maxStoredParcels 20;
}
```

Optionally, the Nusselt number (i.e. the ratio of convective to conductive
heat transfer at a boundary in a fluid) can be output:
```math
Nu = \frac{h L}{\kappa}
```
where
```
Nu | Nusselt number
h | Convective heat transfer coefficient of the flow
L | Characteristic length that defines the scale of the physical system
\kappa | Thermal conductivity of the fluid
```
It was observed in a MPPICDyMFoam simulation involving a single particle
in a moving mesh that the barocentric trajectory of the particle follows
an unexpected path at some arbitrary instant in time.
The issue was tracked to "hitEqn()" where cubicEqn/quadraticEqn computes
one of the roots wrongly due to the discriminant limit we set, e.g. for:
0x^3 + 1.4334549e-33 x^2 - 9.0869006e-10 x + 0.0027666538
Although the discriminant limit was carefully selected to avoid various
problems at the time, the new change is required more due to its exposition
to a wider spectrum of applications.

The main issue here was that reconstructPar is serial but coupled() in
cyclicAMIFvPatch.C could return true if both sides of the patch was present
(this->size() && neighbFvPatch().size()). However, this would result in an
evaluate call in cyclicAMIFvPatchField. This would only work if both sides
were completely contained on the same processor. The change in logic prevents
coupled() from returning true when called in serial for a decomposed case.

- prefix FOAM_MPI and library directories with 'sys-' for system
versions for uniform identication.
WM_MPLIB | libdir (FOAM_MPI) | old naming |
SYSTEMMPI | sys-mpi | mpi |
SYSTEMOPENMPI | sys-openmpi | openmpi-system |
- prefix preferences with 'prefs.' to make them more easily
identifiable, and update bin/tools/create-mpi-config accordingly
Old name: config.{csh,sh}/openmpi
New name: config.{csh,sh}/prefs.openmpi
- additional mpi preferences now available:
* prefs.intelmpi
* prefs.mpich
...
CONFIG: added hook for EASYBUILDMPI (eb-mpi), somewhat like USERMPI
- EasyBuild uses mpicc when compiling, so no explicit wmake rules are
used
ENH: support different major versions for system openmpi
- for example, with
WM_MPLIB=SYSTEMOPENMPI2
defines FOAM_MPI=sys-openmpi2 and thus creates lib/sys-openmpi2
ENH: centralize handling of mpi as 'mpi-rules'
Before:
sinclude $(GENERAL_RULES)/mplib$(WM_MPLIB)
sinclude $(DEFAULT_RULES)/mplib$(WM_MPLIB)
ifeq (,$(FOAM_MPI_LIBBIN))
FOAM_MPI_LIBBIN := $(FOAM_LIBBIN)/$(FOAM_MPI)
endif
After:
include $(GENERAL_RULES)/mpi-rules
- also allows variants such as SYSTEMOPENMPI2 to be handled separately
ENH: provide fallback prefix for cmake detection
STYLE: simplify some shell syntax, avoid uname call in sysFunctions
STYLE: report FOAM_MPI during mpiLib builds
- ensures that subsequent Allwmake scripts know about it.
ENH: add bin/tools/query-detect wrapper for wmake have_* scripts
CONFIG: use project/ThirdParty without additional sanity checks
- no need to test for Allwmake or platforms/ if ThirdParty is located
within the project directory itself.
COMP: add simple mpi test to 00-dummy
- for testing library linkage, etc.
- blockMesh <- extrudeModel <- dynamicMesh
COMP: bad constructor in searchableSphere
- used brace initializer instead of bracket initializer, which
triggered component-wise construction instead of copy/move
construction (gcc 4.8)
STYLE: use uint8_t instead of relying on definition of 'direction'
- first sort the cells into their ijk bins, and restrict testing for
face orientation to those faces with an owner or neighbour that has
an ijk bin.
ENH: ensure polyMesh from PDRblockMesh is marked as AUTO_WRITE
- the particular polyMesh constructor inherits the writeOpt, which
makes is dependent on the caller and thus somewhat fragile for the
top level caller.
- a sphere/spheroid can be specified as a single radius or three radii.
If all three values happen to be identical, they are collapsed to a
single value. Examples,
radius 2;
radius (2 2 2);
radius (2 3 4);
radius (2 2 4);
The search for nearest point on an ellipse or ellipsoid follows the
description given by Geometric Tools (David Eberly), which also
include some pseudo code. The content is CC-BY 4.0
In the search algorithm, symmetry is exploited and the searching is
confined to the first (+x,+y,+z) octant, and the radii are ordered
from largest to smallest.
Searching is optimized for sphere, prolate and oblate spheroids.
- code reduction, documentation, code stubs for spheroid (#1901)
- make searchableSurfaceCollection available as 'collection'
for consistency with other objects
- make handling of verbosity more consistent.
Make all setter return the old value, remove (unused) default
parameter as being counter-intuitive. This makes it easier to
restore the original values.
For example,
const bool oldVerbose = sampler.verbose(false);
...
sampler.verbose(oldVerbose);
- can help when designing/debugging blockMesh layouts
- propagate low-level cellModel methods face() and edge() to cellShape
STYLE: relocate blockMesh OBJ output to application only
- remove blockTopology files in cleanCase function
- improve code consistency in top-level blockMesh, PDRblockMesh
generation.
- consistent with FOAM_SIGFPE etc.
- centralize code as error::useAbort() static function to avoid
scattering the logic throughout the code.
ENH: also accept "0" and "1" string values for Switch
- not the normal path for Switch input (eg, from a dictionary), but
consistent with bool definitions and simplifies string parsing.
This means that `FOAM_SIGFPE=1 application` will now also work.
- use refPtr to simplify some logic.
- avoid copying field if an average will be used
- initialize geometric fields with a uniform value instead of Zero
- minor tweak of method names
- apply bugfix #1889 (longer description elsewhere)
- add -recentre option to shift points according to the bounding box
centre before performing other operations
- add -auto-origin to use the bounding box centre as the origin for
rotations. Has lower priority than the -origin option.
- surfaceTransformPoints now has distinct -read-scale, -write-scale
options (as per surfaceMeshConvert). Silently accepts -scale as
equivalent to -write-scale, for backwards compatibility and
similarity with transformPoints
- add -steps option for surfaceRefineRedGreen for successive
refinement
Allows specification of extrusion path using blockMesh 'edges' syntax.

ENH: add some scalar constants for .org compatibility (#1881)
Although it can very much be a moving target, it can prove partly
useful to have some compatibility constants/methods.
- The wholesale change of 'GREAT' -> 'great' etc (JAN-2018), makes
user coding for multiple versions problematic. When
COMPAT_OPENFOAM_ORG is defined, now define constants (aliases) named
as per the openfoam.org version. Values, however, remain identical.
- For type-safe dictionary value retrieval, we have the templated
get<> methods added around NOV-2018 and deprecated the lookupType
method.
The .org version followed suit in NOV-2019, but opted for renaming
the templated lookupType method as a templated 'lookup' method.
Using this is discouraged, but allowed when COMPAT_OPENFOAM_ORG is
defined.
- flips state while preserving the textual representation.
Eg, OFF <-> ON, YES <-> NO etc.
- fix test case to avoid triggering abort(), which we cannot try/catch
- provides a more direct means of generating a compound token without
an Istream
- add transferCompoundToken() without Istream reference
- mark more token methods as noexcept
- was marked as transitional/deprecated (2018-02), now deleted.
- avoids unexpected stealing of the pointer.
Use the move assignment it that is the intention.
