ENH: Added new createViewFactors utility

See merge request !692

Andrew Heather authored 9 months ago and Kutalmış Berçin committed 8 months ago

Creates view factors for the view factor radiation model.

User-selectable models:

- raySearchEngine: model to generate rays, i.e. face-to-face connections
- viewFactorModel: model to compute the view factors

For visualisation, use:

- Write the view factors as a volume field

    writeViewFactors    yes;

- Write the rays using OBJ format:

    writeRays       yes; // default = no

Participating patches must be in the \c vewFactorWall group, i.e. using the
\c inGroups entry of the "\<case\>/polyMesh/boundary" file.

\verbatim
myPatch
{
    type            wall;
    inGroups        2(wall viewFactorWall);
    ...
}
\endverbatim

Reads:

- <constant>/viewFactorsDict : main controls
- <constant>/finalAgglom : agglomeration addressing (from faceAgglomerate)

Generates:

- <constant>/F : view factors (matrix)
- <constant>/mapDist : map used for parallel running
- <constant>/globalFaceFaces : face addressing

- bugfix for parallel gather of patch values with serial rendering

- can be useful for various orientation-related geometry or mesh
  manipulations during pre-/post-processing:
  * combine with linearDirection to achieve better extrusion results.
  * orientation of transformations, blockMesh, result projections, ...

REGRESSION: missing "value" handling for some surface fields (#3144)

- changes in 8a8b5db9 were overly aggressive.
  Only need to suppress "value" IO for empty patches types

BUG: adjointRotatingWallVelocity causes sensitivities to crash. Fixes #3180

Closes #3180

See merge request !690

- exprValueFieldTag is an extended version of exprValue,
  with additional Field/List uniformity handling

- the exprValueFieldTag reduce() method provides a more efficient
  method than using a regular combine operator. Since fields are
  usually non-uniform, will mostly only need the bitwise reduce and
  not a more expensive gather/combine.

ENH: output of exprValue (scalar type) now includes '.'

- prevents scalar/label ambiguity for values like '100.0', which would
  otherwise be written as '100' and thus interpreted as a label value
  when re-reading.

Sets the particle active flag to false to freeze the particle in space whilst
allowing it to evolve its physical models.
