- Added preLoop, loop and postLoop functions
- Added preIter, mainIter and postIter functions for each SIMPLE
  iteration
- Added addMomentumSource and addPressureSource virtual functions, to
  allow for additions by derived classes

fvOptions are no longer a member of incompressiblePrimalSolver but are
looked up from the registry in each iteration of each primal solver.
This means that the main system/fvOptions dictionary is read by ALL
instances of the primal solvers and the latter no longer have their
own fvOptions dict in optimisationDict. This is safe since each fvOption
is applied to a specific field and in case of many primal solvers, the
primal fields are named differently for each of them.

In addition, simple is now split in preLoop, loop and postLoop phase.
Furthermore, each SIMPLE iteration is broken down to
a preIter, mainIter and postIter phase, to allow for different behaviour
by derived classes.

to the primal and adjoint solver names

Part of the (E)SI shape sensitivities depends of grad(Ua) & nf computed
on the boundary. Up to now, the code was only computing the normal part
of grad(Ua), to avoid the potentially spurious tangential component
which is computed on the cell center and extrapolated to the boundary
faces. However, for some objectives that are strongly related to the
stresses (e.g. moment, stresses), including also the tangential part of
grad(Ua) is necessary for E-SI to replicate the outcome of FI.

Extensive testing on a number of objectives/cases showed
- No regression when including the tangential part
- Improved behaviour in some rare cases (moment, stresses)

Hence, the tangential part is now included by default. The previous code
behaviour can be replicated by setting the useSnGradInTranposeStresses
flag to true.

- controlPointsDefinition is now controled by a class with
  runTimeSelection.
- Added a new controlPointsDefinition option that translates, rotates
  and scales a given box. The required entries have the same meaning as
  in the Paraview 'Transform' filter, facilitating the transition between the
  visual placement of control boxes (e.g. in Paraview) and their setup
  in the code.
- Improved performance during the parameterization, sensitivity
  computation and grid displacement phases by re-using already computed
  basis functions.

in case useSolverNameForFields is set to true.
Used for multi-point optmisation runs.

to allow for constructing different MRF zones for multi-point
optimisation runs

since its behaviour can be replicated by the more general framework for
setting objective targets introduced in 6ee7bc66.

Feature iso distance surface

See merge request Development/openfoam!407

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- adds topology-based segmentation of the surfaces generated with
  distance surfaces. This can occur when the surface terminates
  close to a thin wall gap in the mesh; resulting in a cuts that
  extend into the next region.

  The cutting algorithm does not normally distinguish between these
  types of "ragged" cuts, and legitimate ones (eg, cutting multiple
  pipes). The additional segmentation controls provide for two common
  scenarios:

  largestRegion (pre-filter):
  - The cut cells are checked for topological connectivity and the
    region with the most number of cut cells is retained.
    This handles the "ragged" edge problem.

  nearestPoints (pre-filter):
  - The cut cells split into regions, the regions closest to the
    user-defined points are retained.
    Uses maxDistance for additional control.

  proximity (post-filter):
  - Checks the resulting faces against the original search surface
    and rejects faces with a distance greater than absProximity.

ENH: restructure distance surface geometric filtering

- prefilter cells, which can be used to adjust the distance
  calculation in the far field to the real distance
  (not the normal distance).

  This can also be used to artificially sharpen the transition
  between near/far regions, if required in the future.

- support multiple offsets for cutting plane samples
  and multiple iso-values

Mark OLESEN authored 4 years ago and Andrew Heather committed 4 years ago

- generic isoSurfaceBase. Provides simpler cell-cut detection and
  various functions that can be used for iso-surfaces or when
  preparing prefiltered input for iso-surfaces.

- rudimentary runtime selection

ENH: isoSurface Cell/Topo uses the isoSurfaceBase infrastructure

- simpler cell cut detection, common routines
- ensure that tetMatcher is only called once per cell

ENH: use indirect patch during edge erosion

- lower overhead, allows backtracking (future) if needed

Feature add additional scaling to geometric area overlap calculation inside acmi

See merge request Development/openfoam!374

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

Added 'scale' parameter to cyclicACMI. Scales the amount of 'coupledness' (= mask). Allows opening/closing without mesh motion.

Feature runtime selection geometry

See merge request Development/openfoam!411

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

This adds a 'geometry' scheme section to the system/fvSchemes:

geometry
{
    type            highAspectRatio;
}

These 'fvGeometryMethod's are used to calculate
- deltaCoeffs
- nonOrthoCoeffs
etc and can even modify the basic face/cellCentres calculation.

ENH: Lagrangian - added new PatchInteractionFields cloud function object

See merge request !409

Andrew Heather authored 4 years ago and Andrew Heather committed 4 years ago

Creates volume fields whose boundaries are used to store patch interaction
statistics.

Current field output per patch face:
- \<cloud\>\<model\>:count - cumulative particle hits
- \<cloud\>\<model\>:mass - cumuluative mass of hitting particles

Fields can be reset according to:
- none: fields are not reset
- timeStep: reset at each time step
- writeTime: reset at each write time

Usage

    patchInteractionFields1
    {
        type            patchInteractionFields;
        resetMode       writeTime;
    }

The generalizedNewtonian viscocity models were ported from
the org version and added to the laminar turbulence framework.

This allows use in compressible and incompressible solvers
through the turbulence dictionary under the laminar sub-dictionary.

The thermal laminar viscosity is taken from the thermo for solvers
that use thermo library or from the transportProperties dictionary
for incompressible solvers.

At the moment the option to include viscocity models through the
transportDict is still available.

The icoTabulated equation of state was ported from the org version.

STYLE: use 'model' instead of 'laminarModel' in tutorials

- implicitly enabled when timeStampMaster (default) is used
  for the fileModificationChecking

- When running with non-distributed roots (eg, NFS-share) read for
  processor directories on master only and send to sub-processes
  instead individual reads.

- If disabled (old default, or when running with distributed roots),
  uses the regular fileHandler readDir, which may perform readDir
  on each processor. Potentially slow startup times on large systems.
