This is useful when applying an experimentally obtained profile as an
inlet condition:
Example of the boundary condition specification:
\verbatim
myPatch
{
type fixedProfile;
profile csvFile;
profileCoeffs
{
nHeaderLine 0; // Number of header lines
refColumn 0; // Reference column index
componentColumns (1 2 3); // Component column indices
separator ","; // Optional (defaults to ",")
mergeSeparators no; // Merge multiple separators
fileName "Uprofile.csv"; // name of csv data file
outOfBounds clamp; // Optional out-of-bounds handling
interpolationScheme linear; // Optional interpolation scheme
}
direction (0 1 0);
origin 0;
}
\endverbatim
or a simple polynomial profile:
Example setting a parabolic inlet profile for the PitzDaily case:
\verbatim
inlet
{
type fixedProfile;
profile polynomial
(
((1 0 0) (0 0 0))
((-6200 0 0) (2 0 0))
);
direction (0 1 0);
origin 0.0127;
}
\endverbatim

across all the phases in an Eulerian multi-phase simulation.
Intended to be used with copiedFixedValue to ensure that phase wall
temperature are consistent:
- Set 'fixedMultiPhaseHeatFlux' boundary for one of the phases
- Use 'copiedFixedValue' for all the other phases.

Provides run-time selection of buoyancy sources for compressible solvers
Replaces the built-in buoyancy sources in XiFoam, reactingFoam and
rhoReactingFoam.
e.g. in constant/fvOptions specify
momentumSource
{
type buoyancyForce;
buoyancyForceCoeffs
{
fieldNames (U);
}
}
and optionally specify the buoyancy energy source in the enthalpy
equation:
energySource
{
type buoyancyEnergy;
buoyancyEnergyCoeffs
{
fieldNames (h);
}
}
or internal energy equation
energySource
{
type buoyancyEnergy;
buoyancyEnergyCoeffs
{
fieldNames (e);
}
}
New lift model supporting near-wall damping using the new
wallDampingModels.
e.g.
lift
(
(air in water)
{
type wallDamped;
lift
{
type constantCoefficient;
Cl 0.5;
}
wallDamping
{
type linear;
Cd 0.5;
}
}
);
in which a linear near-wall damping function min(y/(Cd*d), 1) is applied to the constant
coefficient lift model. Additional wall-damping functions will be added.
to allow iteration over the energy equations to improve stability for phase-change.
Additionally if nEnergyCorrectors is set to 0 the energy equations are
not solved which may be beneficial during the startup of some cases.
Usage: createTurbulenceFields [OPTIONS]
options:
-case <dir> specify alternate case directory, default is the cwd
-constant include the 'constant/' dir in the times list
-fields <wordReList>
specify which turbulence fields (k, epsilon, omega, R) to
write - eg '(k omega)' or '(R)' or '(.*)'.
-latestTime select the latest time
-newTimes select the new times
-noFunctionObjects
do not execute functionObjects
-noZero exclude the '0/' dir from the times list, has precedence
over the -withZero option
-parallel run in parallel
-roots <(dir1 .. dirN)>
slave root directories for distributed running
-time <ranges> comma-separated time ranges - eg, ':10,20,40:70,1000:'
