Uses sample configuration files in $FOAM_ETC/caseDicts, including
utility configuration files and packaged function objects. For
example:
foamGet decomposeParDict
foamGet extrudeMeshDict
foamGet createPatchDict
foamGet surfaces
Files are copied into the system directory by default, otherwise a
different target directory can be specified with -target|-t option.

The subject can relate to models (including boundary conditions and
packaged function objects), applications and scripts. For example:
foamInfo simpleFoam
foamInfo kEpsilon
foamInfo turbulentIntensityKineticEnergyInlet
foamInfo fixedTemperatureConstraint
foamInfo surfaces
foamInfo foamNewBC
The output includes the following:
- File: the location of the relevant source code header file;
- Description details from the header file;
- Usage details from the header file;
- Examples: a list of relevant cases from the tutorials directory.
foamInfo includes the -web|-w and -browser|-b options to open relevant
HTML source code documentation at https://cpp.openfoam.org

This method waits until all the threads have completed IO operations and
then clears any cached information about the files on disk. This
replaces the deactivation of threading by means of zeroing the buffer
size when writing and reading of a file happen in sequence. It also
allows paraFoam to update the list of available times.

Mesh motion solver simple linear expansion and contraction of a mesh
region defined by a motion axis and the extents of the motion.
Example:
\verbatim
dynamicFvMesh dynamicMotionSolverFvMesh;
motionSolver displacementLinearMotion;
axis (0 1 0);
xFixed 0.8;
xMoving 0;
displacement table
(
(0 0)
(4 0.7)
);
\endverbatim
This mesh is compressed between \c xFixed and \c xMoving in the direction
\c axis between time 0 and 4 with a maximum displacement of 0.7.
The mesh beyond \c xFixed is fixed and beyond \c xMoving moves with maximum
displacement.
The sampled sets have been renamed in a more explicit and consistent
manner, and two new ones have also been added. The available sets are as
follows:
arcUniform: Uniform samples along an arc. Replaces "circle", and
adds the ability to sample along only a part of the circle's
circumference. Example:
{
type arcUniform;
centre (0.95 0 0.25);
normal (1 0 0);
radial (0 0 0.25);
startAngle -1.57079633;
endAngle 0.52359878;
nPoints 200;
axis x;
}
boundaryPoints: Specified point samples associated with a subset of
the boundary. Replaces "patchCloud". Example:
{
type boundaryPoints;
patches (inlet1 inlet2);
points ((0 -0.05 0.05) (0 -0.05 0.1) (0 -0.05 0.15));
maxDistance 0.01;
axis x;
}
boundaryRandom: Random samples within a subset of the boundary.
Replaces "patchSeed", but changes the behaviour to be entirely
random. It does not seed the boundary face centres first. Example:
{
type boundaryRandom;
patches (inlet1 inlet2);
nPoints 1000;
axis x;
}
boxUniform: Uniform grid of samples within a axis-aligned box.
Replaces "array". Example:
{
type boxUniform;
box (0.95 0 0.25) (1.2 0.25 0.5);
nPoints (2 4 6);
axis x;
}
circleRandom: Random samples within a circle. New. Example:
{
type circleRandom;
centre (0.95 0 0.25);
normal (1 0 0);
radius 0.25;
nPoints 200;
axis x;
}
lineFace: Face-intersections along a line. Replaces "face". Example:
{
type lineFace;
start (0.6 0.6 0.5);
end (0.6 -0.3 -0.1);
axis x;
}
lineCell: Cell-samples along a line at the mid-points in-between
face-intersections. Replaces "midPoint". Example:
{
type lineCell;
start (0.5 0.6 0.5);
end (0.5 -0.3 -0.1);
axis x;
}
lineCellFace: Combination of "lineFace" and "lineCell". Replaces
"midPointAndFace". Example:
{
type lineCellFace;
start (0.55 0.6 0.5);
end (0.55 -0.3 -0.1);
axis x;
}
lineUniform: Uniform samples along a line. Replaces "uniform".
Example:
{
type lineUniform;
start (0.65 0.3 0.3);
end (0.65 -0.3 -0.1);
nPoints 200;
axis x;
}
points: Specified points. Replaces "cloud" when the ordered flag is
false, and "polyLine" when the ordered flag is true. Example:
{
type points;
points ((0 -0.05 0.05) (0 -0.05 0.1) (0 -0.05 0.15));
ordered yes;
axis x;
}
sphereRandom: Random samples within a sphere. New. Example:
{
type sphereRandom;
centre (0.95 0 0.25);
radius 0.25;
nPoints 200;
axis x;
}
triSurfaceMesh: Samples from all the points of a triSurfaceMesh.
Replaces "triSurfaceMeshPointSet". Example:
{
type triSurfaceMesh;
surface "surface.stl";
axis x;
}
The headers have also had documentation added. Example usage and a
description of the control parameters now exists for all sets.
In addition, a number of the algorithms which generate the sets have
been refactored or rewritten. This was done either to take advantage of
the recent changes to random number generation, or to remove ad-hoc
fixes that were made unnecessary by the barycentric tracking algorithm.
