nLimiterIter: Number of iterations during limiter construction
3 (default) is sufficient for 3D simulations with a Courant number 0.5 or so
For larger Courant numbers larger values may be needed but this is
only relevant for IMULES and CMULES
smoothLimiter: Coefficient to smooth the limiter to avoid "diamond"
staggering patters seen in regions of low particle phase-fraction in
fluidised-bed simulations.
The default is 0 as it is not needed for all simulations.
A value of 0.1 is appropriate for fluidised-bed simulations.
The useful range is 0 -> 0.5.
Values larger than 0.5 may cause excessive smearing of the solution.
Now interaction methods must be specified for all non-coupled patches.
If this approach proves irritating a warning rather than an error could
be generated.

Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
writeVolume yes;
The initial volume is written in the log and data file header e.g.:
# Source : all
# Cells : 3829
# Volume : 9.943164e-01
Also added
sumMag | sum of component magnitudes
Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
writeTotalArea yes;
The initial total area is written in the log and data file header e.g.:
# Source : faceZone f0
# Faces : 8
# Area : 1.063860e-02
Description
Specify an etc file to include when reading dictionaries, expects a
single string to follow.
Searches for files from user/group/shipped directories.
The search scheme allows for version-specific and
version-independent files using the following hierarchy:
- \b user settings:
- ~/.OpenFOAM/\<VERSION\>
- ~/.OpenFOAM/
- \b group (site) settings (when $WM_PROJECT_SITE is set):
- $WM_PROJECT_SITE/\<VERSION\>
- $WM_PROJECT_SITE
- \b group (site) settings (when $WM_PROJECT_SITE is not set):
- $WM_PROJECT_INST_DIR/site/\<VERSION\>
- $WM_PROJECT_INST_DIR/site/
- \b other (shipped) settings:
- $WM_PROJECT_DIR/etc/
An example of the \c \#includeEtc directive:
\verbatim
#includeEtc "etcFile"
\endverbatim
The usual expansion of environment variables and other constructs is
retained.
Note that currently when transportProperties is changed sigma is re-read
from this dictionary but cAlpha is read from fvSolution but cAlpha is
not re-read when fvSolution is changed but transportProperties is not
touched. To avoid this problem cAlpha would need to be moved to the
transportProperties dictionary which is not ideal or moved out of the
interfaceProperties class back to the top-level solver.

This allows for more than one of these data types to be specified in a dictionary
Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=1652
e.g.
<entryName> csvFile;
<entryName>Coeffs
{
nHeaderLine 4;
refColumn 0; // reference column index
componentColumns (1 2 3); // component column indices
separator ","; // optional (defaults to ",")
mergeSeparators no; // merge multiple separators
fileName "fileXYZ"; // name of csv data file
outOfBounds clamp; // optional out-of-bounds handling
interpolationScheme linear; // optional interpolation scheme
}
Improves stability and convergence of systems in which drag dominates
e.g. small particles in high-speed gas flow.
Additionally a new ddtPhiCorr strategy is included in which correction
is applied only where the phases are nearly pure. This reduces
staggering patters near the free-surface of bubble-column simulations.
