- all flags before loaders. Avoids "uninitialized when used here"
warning while preserving the field ownership logic.
- relocate override of updateT basicThermo into constructor body
for clearer logic and initialization
STYLE: plain bool instead of Switch for dpdt flag
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).
- 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.
Currently only applied to the fanFvPatchField, e.g.
plane
{
type fan;
patchType cyclic;
jump uniform 0;
value uniform 0;
uniformJump false;
// Optional under-relaxation
relax 0.2;
...
}
- combines region-based and proximity-based filtering
proxityRegions (post-filter):
Checks the distance of the resulting faces against the original
search surface. Filters based on the area-weighted distance
of each topologically connected region.
If the area-weighted distance of a region is greater than
\c absProximity, the entire region is rejected.
STYLE: 'proxityFaces' as newer synonym for 'proximity' filter
- snGrad, internalField, neighbourField.
Functional use as per swak: "... + internalField(T) ..."
ENH: additional volume/patch expressions
- deltaT()
STYLE: rename exprDriverWriter -> fvExprDriverWriter
- the original class name was a misnomer since it holds a reference
to fvExprDriver
BUG: expression faceToPoint/pointToFace definitions were flipped
ENH: refactor expression hierarchy and code style
- handle TimeState reference at the top-level for simpler derivations
- unified internal search parameters (cruft)
- support wordRes for selecting patch names
- ownerPolyPatch specification is now optional, which simplifies input
and also supports a faMesh spanning different patches but with a
single boundary condition.
Alternatively, can specify more granularity if required.
```
polyMeshPatches ( "top.*" );
boundary
{
inlet1
{
type patch;
ownerPolyPatch top1; // <- specific to this portion
neighbourPolyPatch inlet;
}
inlet2
{
type patch;
ownerPolyPatch top2; // <- specific to this portion
neighbourPolyPatch inlet;
}
outlet
{
type patch;
neighbourPolyPatch outflow;
}
bound
{
type symmetry;
neighbourPolyPatch bound;
}
}
```
Prior to the commit, initial residual fields were registered by
the `setResidualField()` function of a linear solver with a field name
prefixed by `residual:`. However, `solverInfo` FO could only access to
the initial residual fields prefixed by `initialResidual:`.
Due to this discrepancy, using `solverInfo` FO with `writeResidualFields=true`
option was resulting in empty residual fields to be output.
- ENH: turbulentDFSEMInlet: add normalisation factors for
input Reynolds stresses, mean velocity and integral-length
scales as entries `Uref` and `Lref`.
- ENH: turbulentDFSEMInlet: add scaling factor entries, `scale`
and `m`, to enable users to tune C1 normalisation coefficient,
if need be.
- BUG: turbulentDFSEM: (fixes#1004#1744#2089)
- see #2090 for theoretical issues related to the DFSEM method.
