It has been observed that the finite-area framework is prone to numerical
issues when zero-valued edge lenghts, edge/face normals and face areas exist.

To improve exception handling at identified code sections to gracefully
overcome math errors, the problematic entities are lower-bounded by SMALL.

- README updated to v2212

- paraview (5.11.0), petsc (3.18.2), adios (2.8.3), scotch (7.0.1)

STYLE: init label variants with std::sqrt + double (compile-time invariant)

Specified using the optional 'omega' entry (Function1 type), e.g. for a constant
value:

      omega           12.56;

Note that the swirl contribution is applied in addition to the velocity set by
the 'flowType' option. For example, for the 'constantVelocity' option, parcels
are initially set the velocity according to the UMag and direction/cone angle;
the swirl velocity is then added.

ENH: dynamicContactAngleForce: new finite-area contact-angle force model

DEFEATURE: merge fa-perturbedTemperatureDependent into dynamicContactAngle

ENH: added option to control log frequency of lagrangian calculations

See merge request Development/openfoam!583

Andrew Heather authored 2 years ago and Mark OLESEN committed 2 years ago

STYLE: lagrangian intermediate library - renamed log_ to logToFile_ to disambiguate against output to Info

- similar to surface writing formats, also support optional
  dictionary of reading options. The main beneficiary of this is the
  ensight surface reader:

  readOptions
  {
      ensight
      {
          masterOnly true;
      }
  }

  This will restrict reading to the master rank. Surfaces and values
  read will be broadcast to the other ranks, with the intention of
  reducing load on the filesystem.

ENH: add writing of Dimensioned fields for areaWrite functionObject

- can be useful for examining finite-area source terms

- improve communicator wrapping
- avoid indexing errors when using partial subranks
- UPstream::is_subrank (for testing partial subranks)
