cellZones and pointZones can now be created in one action without the
need to first create a cellSet or pointSet and converting that to the
corresponding zone, e.g.
actions
(
// Example: create cellZone from a box region
{
name c0;
type cellZoneSet;
action new;
source boxToCell;
sourceInfo
{
box (0.04 0 0)(0.06 100 100);
}
}
);
postProcess -func MachNo
previously generated the warning
Executing functionObjects
--> FOAM Warning : functionObjects::MachNo MachNo cannot find required field U
which is incorrect; the field 'U' is available but the
thermophysicalProperties is not. Now 'postProcess' generates the
warning:
Executing functionObjects
--> FOAM Warning : functionObjects::MachNo MachNo cannot find required object thermophysicalProperties of type fluidThermo
--> FOAM Warning : functionObjects::MachNo MachNo failed to execute.

Added the interfacial pressure-work terms according to:
Ishii, M., Hibiki, T.,
Thermo-fluid dynamics of two-phase flow,
ISBN-10: 0-387-28321-8, 2006
While this is the most common approach to handling the interfacial
pressure-work it introduces numerical stability issues in regions of low
phase-fraction and rapid flow deformation. To alleviate this problem an
optional limiter may be applied to the pressure-work term in either of
the energy forms. This may specified in the
"thermophysicalProperties.<phase>" file, e.g.
pressureWorkAlphaLimit 1e-3;
which sets the pressure work term to 0 for phase-fractions below 1e-3.
For particularly unstable cases a limit of 1e-2 may be necessary.
The best of the current options is to use the latest version of
exuberant ctags (which has a new C++ parser) to generate both
declaration and definition tags.
gtags works to some extent and provides additional information about the
function signatures but the C++ parser is not accurate and misses scope
information. gtags can be used with the ctags parser which is effective
but looses the primary advantage of gtags being able to provide function
signatures so support has been switched-off by default.
ebrowse does not appear to be very useful for traversing the OpenFOAM
class tree and the support has been switched-off by default.
