The FOAM file format has not changed from version 2.0 in many years and so there
is no longer a need for the 'version' entry in the FoamFile header to be
required and to reduce unnecessary clutter it is now optional, defaulting to the
current file format 2.0.
Specifying default fields for complex and multi-phase cases is simplified and
generalized by using wildcards to select sets of related field names, e.g.
defaultFields (p p_rgh U "U\..*" T "T\..*" "alpha\..*");
selects the velocity, temperature and phase-fraction fields of all phases in
addition to the pressure fields.
The default patch types specified in the new defaultPatchTypes entry of the
etc paraFoam configuration dictionaries:
defaultPatchTypes (patch wall);
Wildcards are supported, for example to specify that all patches loaded simply set
defaultPatchTypes to
defaultPatchTypes (".*");
The new default paraFoam configuration is in the files OpenFOAM-dev/etc/paraFoam
containing the entry
defaultFields (U p p_rgh T alpha.water alpha.air);
specifying the set of fields which are loaded by default if available. This
setting maybe overridden by providing additional paraFoam configuration files in
any of the OpenFOAM etc directories searched, listed using
foamEtcFile -list
e.g.
~/.OpenFOAM/dev
~/.OpenFOAM
~/OpenFOAM/site/dev
~/OpenFOAM/site
~/OpenFOAM/OpenFOAM-dev/etc
The new configurable set of default fields loaded replaces the original hard-coded default of
"p" and "U" and is much more convenient for current OpenFOAM usage.
