- 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.

AMI improvements

See merge request !468

Andrew Heather authored 4 years ago and Mattijs Janssens committed 3 years ago

- 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.

ENH: Added new multiRegion function object

See merge request !470

Andrew Heather authored 3 years ago and Mark OLESEN committed 3 years ago

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

ENH: new multiFieldValue function object

See merge request !469

Andrew Heather authored 3 years ago and Mark OLESEN committed 3 years ago

    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  ...

TUT: add missing restore0Dir (finiteArea)

ENH: Added under-relaxation to jump conditions

See merge request !467

Andrew Heather authored 3 years ago and Andrew Heather committed 3 years ago

Example:

    plane
    {
        type            fan;
        patchType       cyclic;
        jump            uniform 0;
        value           uniform 0;
        uniformJump     false;

        relax           0.2;

        jumpTable       ( (1000 0) (-200 1) (20 2) (-0.75 3) );

        // Optional minimum jump value
        minJump         0;
    }

Andrew Heather authored 3 years ago and Andrew Heather committed 3 years ago

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;

        ...
    }

ENH: add proximityRegions filter to distanceSurface (#2108)

See merge request !460

- 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;
      }
  }
  ```

- move unreferenced Config.md to wiki content

- additional -serial/-parallel option:
  prefer Allrun-serial or Allrun-parallel if available

- optional -output=DIR to preserve output

ENH: report missing tutorials/ directory in RunFunctions

- add to wmakeFunctions to ensure it works even without 'make' being
  installed. Exit immediately after -show-api for consistency with
  -version.

foamEtcFile:
  - drop warnings for some old (pre-v1812) defunct options
    and simply flag as unknown options.
  - handle -version, --version as equivalent to -show-api

BUG: fixing various bugs for v2106
