The semiPermeableBaffleMassFraction boundary condition can now calculate
the mass flux as proportional to the difference in mole fraction or
partial pressure. A mass fraction difference driven transfer is also
still possible. An additional keyword, "input" has been added which is
used to select the variable used to calculate the transfer. An example
specification is as follows:
baffle
{
type semiPermeableBaffleMassFraction;
samplePatch membranePipe;
c 0.1;
input massFraction;
value uniform 0;
}
In order to facilitate this, a "W" method to get the molar mass on a
patch has been added to the thermodynamics. To avoid name-clashes,
methods that generate per-species molar masses have been renamed "Wi".

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.
