- patchFields now get mapped (instead of created)
- with -consistent it now maps all patches except for processor ones (they are
the only ones that are processor-local)
- all constraint patches get evaluated after mapping to bring them up to date.

dictionary files of a particular name and extracts entries of a
particular keyword, sorting results into a unique list.
For example,
foamSearch $FOAM_TUTORIALS laplacianSchemes.default fvSchemes
produces...
default Gauss linear corrected;
default Gauss linear limited corrected 0.33;
default Gauss linear limited corrected 0.5;
default Gauss linear orthogonal;
default Gauss linear uncorrected;
default none;
Uses the fantastic foamDictionary utility.
Description
Constrain the field values within a specified region.
For example to set the turbulence properties within a porous region:
\verbatim
porosityTurbulence
{
type scalarFixedValueConstraint;
active yes;
scalarFixedValueConstraintCoeffs
{
selectionMode cellZone;
cellZone porosity;
fieldValues
{
k 30.7;
epsilon 1.5;
}
}
}
\endverbatim
See tutorials/compressible/rhoSimpleFoam/angledDuctExplicitFixedCoeff
constant/fvOptions for an example of this fvOption in action.
The modes of operation are set by the dimensions of the pressure field
to which this boundary condition is applied, the \c psi entry and the value
of \c gamma:
\table
Mode | dimensions | psi | gamma
incompressible subsonic | p/rho | |
compressible subsonic | p | none |
compressible transonic | p | psi | 1
compressible supersonic | p | psi | > 1
\endtable
For most applications the totalPressure boundary condition now only
requires p0 to be specified e.g.
outlet
{
type totalPressure;
p0 uniform 1e5;
}
updateCoeffs(const scalarField&) -> updateWeightedCoeffs(const scalarField&)
to avoid confusion with other specialized forms of updateCoeffs.
