1) Adding subMesh capabilities to momentumError and div FOs.
- A subMesh is created from cellZones.
- The operators (div, etc) are only calculated in the subMesh.
2) Optionally, halo cells can be added to the cellZones.
3) New helper class to handle the subMesh creation and field mapping.
- add setter/getter methods for number of grow/shrink steps,
which allows reuse of the same object.
- remove the lower input hard-limit of 1 step, to allow definition of
a no-op filter.
- drop early exit from grow/shrink cycle (potential parallel issues).
- previously a function (unlike the csh version) but since bashrc and
setup have been split -> replace with inline definition
STYLE: formatting/wording for openfoam starters
TUT: simplify controlDict modification, add default substitution
ENH: accept '/' for end-of-options terminator (etc/openfoam)
- makes the application or service more apparent.
* eg. /usr/bin/openfoam / blockMesh
* vs. /usr/bin/openfoam -- blockMesh
Accept lone '-' as the end-of-options terminator, as per bash
- Adjust handling of openfoam '-c' option to flag that a command-string
will appear, but continue with option parsing.
Consistent with bash definition.
- in the 'auto' mode (now the default), it will use cleanCase and also
remove the 0/ directory if a 0.orig/ directory also exists.
This corresponds to a frequent idiom and can be used quite safely
for most cases.
ENH: add -serial / -parallel preference for foamRunTutorials
- adjust commented-out evaluation to avoid warnings.
With code like this
```
#if 0
nxin #eval{ round($nxin / 5) };
#endif
```
The handling of the "#if 0 / #endif" clause uses the plain ISstream
parser to tokenize. This means that the "round(" is parsed as a word
with a mismatched closing ')', whereas the "#eval" parser will slurp
everything in until the closing brace and send it off as a string
to the expression parser.
- Added new faceAreaWeightAMI2D AMIMethod:
- performs intersection using a new 2D triangle class;
- candidate face matches set using an AABBTree method (vs advancing front for
faceAreaWeightAMI).
- Use by setting the AMIMethod entry when specifying the AMI in the
constant/polyMesh/boundary file, e.g.
AMI
{
type cyclicACMI;
AMIMethod faceAreaWeightAMI2D; // new method
Cbb 0.1; // optional coefficient
nFaces 1000;
startFace 100000;
matchTolerance 0.0001;
transform noOrdering;
neighbourPatch AMI1;
nonOverlapPatch AMI1_non_overlap;
}
- The optional Cbb coeffcient controls the size of the bounding box used when
looking for candidate pairs; the value of 0.1 is the default and worked well
for a large range of test cases. For badly matched AMI patches this may need
to be increased.
- Deprecated the partialFaceAreaWeightAMI class - primarily used by ACMI:
- functionality now offered by the AMI variants.
- prghPermeableAlphaTotalPressure for p_rgh
- pressurePermeableAlphaInletOutletVelocity for U
- new helper class for pressure-related BCs: updateableSnGrad
Wrapper that clones the supplied object for each region.
Simplifies the setup of identical post-processing requirements for
multi-region cases.
Applies the supplied function to all regions by default.
Example of function object specification:
multiRegion
{
type multiRegion;
libs (utilityFunctionObjects);
...
function
{
// Actual object specification
type fieldMinMax;
libs (fieldFunctionObjects);
fields (<field1> .. <fieldN>);
}
// Optional entries
regions (region1 region2);
}
Where the entries comprise:
Property | Description | Reqd | Default
type | Type name: multiRegion | yes |
function | Function object sub-dictionary | yes |
regions | List of region names | no | all
Computes a selected operation between multiple \c fieldValue function
objects.
The operation is applied to all results of each \c fieldValue object.
Note
Each object must generate the same number and type of results.
Usage
Minimal example by using \c system/controlDict.functions:
multiFieldValue1
{
// Mandatory entries (unmodifiable)
type multiFieldValue;
libs (fieldFunctionObjects);
// Mandatory entries (runtime modifiable)
operation subtract;
// List of fieldValue function objects as dictionaries
functions
{
region1
{
...
}
region2
{
...
}
...
regionN
{
...
}
}
// Optional (inherited) entries
...
}
where the entries mean:
Property | Description | Type | Req'd | Dflt
type | Type name: multiFieldValue | word | yes | -
libs | Library name: fieldFunctionObjects | word | yes | -
operation | Operation type to apply to values | word | yes | -
functions | List of fieldValue function objects | dict | yes | -
\endtable
Options for the \c operation entry:
add | add
subtract | subtract
min | minimum
max | maximum
average | average
Deprecated fieldValueDelta
- The fieldValueDelta function object was originally written to compute the
difference between two fieldValue-type function objects. The multiFieldValue
object name better describes its purpose whilst being able to operate on an
arbitrary number of fieldValue-type objects.
