- for workflows with appearing/disappearing patches (for example)
can specify that empty surfaces should be ignored or warned about
instead of raising a FatalError.
Note that this handling is additional to the regular top-level
"errors" specification. So specifying 'strict' will only actually
result in a FatalError if the "errors" does not trap errors.
- "ignore" : any empty surfaces are simply ignored and no
file output (besides the header).
- "warn" : empty surfaces are warned about a few times (10)
and the file output contains a NaN entry
- "strict" : corresponds to the default behaviour.
Throws a FatalError if the surface is empty.
This error may still be caught by the top-level "errors" handling.
- ensure surface writing is time-step and nFields aware.
This avoids overwriting (ignoring) previous output fields.
- allow sampled surfaces to be used for weight fields as well.
Not sure why this restriction was still there.
- remove old compatibility reading of orientedFields.
Last used in v1612, now removed.
- only use face sampling. For surfaceFieldValue we can only do
something meaningful with face values.
ENH: modify interface methods for surfaceWriter
- replace direct modification of values with setter methods.
Eg,
old: writer.isPointData() = true;
new: writer.isPointData(true);
This makes it possible to add internal hooks to catch state changes.
ENH: allow post-construction change to sampledSurface interpolation
- rename interpolate() method to isPointData() for consistency with
other classes and to indicate that it is a query.
- additional isPointData(bool) setter method to change the expected
representation type after construction
- remove 'interpolate' restriction on isoSurfacePoint which was
previously flagged as an error but within sampledSurfaces can use
sampleScheme cellPoint and obtain representative samples.
Relax this restriction since this particular iso-surface algorithm
is slated for removal in the foreseeable future.
- weight fields are combined by multiplication
- volFieldValue:
* 0-N scalar fields
- surfaceFieldValue:
* 0-N scalar fields
* 0-1 vector fields
In some cases this can be used to avoid creating additional
fields.
weightFields (rho U);
vs.
derivedFields (rhoU);
weightField rhoU;
- additional "names" entry to specify a word/regex list of selections
For example,
{
type patch;
name inlets;
names ("inlet_[0-9].*" inlet);
}
- if "names" exists AND contains a literal (non-regex) that can be used
as a suitable value for "name", the "name" entry becomes optional.
For example,
{
type patch;
names ("inlet_[0-9].*" inlet);
// inferred name = inlet
}
- reduce some overhead in surfaceFieldValue
TUT: surfaceFieldValue on patches : reactingParcelFoam/verticalChannel
ENH: update libs of etc/caseDicts/postProcess items
ENH: ensure destructor=default
ENH: ensure constness
ENH: ensure no 'copy construct' and 'no copy assignment' exist
TUT: add examples of function objects with full set
of settings into a TUT if unavailable
TUT: update pisoFoam/RAS/cavity tutorial in terms of usage
- prior to sampledSurface supporting different interpolation schemes a
workaround means was used to simulate cellPoint -> face
interpolation, with averaging of vertex interpolation.
We instead now use cellPoint interpolation directly for the face
values when 'interpolate=true'.
- fits better into the general sampling framework, improves flexibilty
and allows code reduction.
ENH: include surface fields on sampledSurfaces that support it
- can be useful either for flow-rate weighting where backflow
is to be ignored in the average, or for flow-rate weighting
on surfaces with inconsistent orientation.
Reworked to code to make better use of Enum (the NamedEnum
replacement). Enum doesn't require contiguous enumeration values,
which lets us use bitmasking of similar operations to reduce
duplicate code.
- this makes it possible to perform additional operations
on surface values that have been previously sampled.
- support vectorField for weighting operations.
- reduce overhead by avoiding creation of weight fields, Sf fields
and combined surface geometries unless they are actually required.
- extend some similar concepts and operations to volFieldValue
