- align Switch more with Enum.
Now have find(), found() static methods.
Constructors with failsafe option.
The find() method makes for clearer coding:
OLD
Switch sw(some_string, true); // NB: true = allowBad
if (sw.valid()) ...
NOW
Switch sw = Switch::find(some_string);
if (sw.good()) ...
or
if (Switch::found(some_string)) ...
- improve construct from dictionary to handle all valid token types.
Previously just read in a word.
- Remove asText() method - replaced by c_str() and str() several
versions ago.
- renamed 'core/' -> 'base/' to avoid gitignore masking when re-adding
files
- rename 'nas/' to 'nastran/' for more clarity
- relocated OBJstream from surfMesh to fileFormats
STYLE: remove unused parseNASCoord. Was deprecated 2017-09
- includes restructuring and simplification of low-level ensight part
handling and refactor of backends to improve code reuse.
foamToEnsight
-------------
* new cellZone support.
This was previously only possible via a separate foamToEnsightParts
utility that was not parallelized.
* support for point fields.
* `-nearCellValue` option (as per foamToVTK)
* data indexing now uses values from the time index.
This is consistent with the ensightWrite function object and
can help with restarts.
* existing ensight directories are removed, unless the -no-overwrite
option is supplied
foamToEnsightParts
------------------
* now redundant and removed.
ensightOutputSurface (new class)
--------------------------------
* a lightweight wrapper for point/face references that is tailored
for the ensightSurfaceWriter. It uses compact face/point information
and is serial only, since this is the format requirements from the
surfaceWriter class.
ensightMesh (revised class)
---------------------------
* now only holds a polyMesh reference, which removes its dependency
on finiteVolume and allows it to be relocated under fileFormats
instead of conversion.
Removed classes: ensightParts, ensighPartFaces, ensightPartCells
- these were used by foamToEnsightParts, but not needed anymore.
- remove (unused) Istream constructors, prune some unused methods,
rationalize write() vs writeDict().
Deprecate inconsistent construction order.
- handle empty names for ".ftr" surface patches (for plain triSurface
format) with double-quoted strings for more reliable streaming.
Written on a single line.
This is _backward_ compatible, but if users have been parsing these
files manually, they will need to adjust their code.
Previously:
```
(
frt-fairing:001%1
empty
windshield:002%2
empty
...
)
```
Updated (with example handling of empty name):
```
(
frt-fairing:001%1 empty
windshield:002%2 ""
...
)
```
The controlBoxes wordList was removed from NURBS3DVolume in the
pre-release phase but writeMorpherCPs was not updated accordingly.
TUT: added the invocation of writeMorpherCPs in one of the tutotials to
help identify future regression
- the PDRsetFields utility processes a set of geometrical obstructions
to determine the equivalent blockage effects.
These fields are necessary inputs for PDRFoam calculations.
After setting up the geometries, the -dry-run option can be used to
generate a VTK file for diagnosis and post-processing purposes.
- this is an initial release, with improvements slated for the future.
NOTE
- the field results may be less than fully reliable when run in
single-precision. This howver does not represent a realistic
restriction since the prepared fields target a combustion
application which will invariably be double-precision.
- The previous option 'write-nut' controlled the writing of turbulence
nut, but other turbulence fields were always written.
These have been shown to be a source of instability for many cases.
This commit replaces the 'write-nut' option by a 'writeTurbulenceFields'
option that controls the writing of all turbulence fields.
If not set, only the velocity field is written.
For compatibility, the old 'write-nut' option is still recognized
but is redirected to 'writeTurbulenceFields'.
The adjoint library is enhanced with new functionality enabling
automated shape optimisation loops. A parameterisation scheme based on
volumetric B-Splines is introduced, the control points of which act as
the design variables in the optimisation loop [1, 2]. The control
points of the volumetric B-Splines boxes can be defined in either
Cartesian or cylindrical coordinates.
The entire loop (solution of the flow and adjoint equations, computation
of sensitivity derivatives, update of the design variables and mesh) is
run within adjointOptimisationFoam. A number of methods to update the
design variables are implemented, including popular Quasi-Newton methods
like BFGS and methods capable of handling constraints like loop using
the SQP or constraint projection.
The software was developed by PCOpt/NTUA and FOSS GP, with contributions from

- silently deprecate 'startsWith', 'endsWith' methods
(added in 2016: 2b14360662), in favour of
'starts_with', 'ends_with' methods, corresponding to C++20 and
allowing us to cull then in a few years.
- handle single character versions of starts_with, ends_with.
- add single character version of removeEnd and silently deprecate
removeTrailing which did the same thing.
- drop the const versions of removeRepeated, removeTrailing.
Unused and with potential confusion.
STYLE: use shrink_to_fit(), erase()
- drop plugin support for Qt4 (old paraview)
- handle upcoming changes in VTK version naming in CMake files
* VTK_MAJOR_VERSION becomes VTK_VERSION_MAJOR etc.
