- retain group information when copying zones
- support construct empty (add details later)
- improve consistency for zone and boundaryMesh construction
- support front/back/both selection for faceZoneToCell
STYLE: prefer faceZone patch() method instead of operator()
STYLE: use std::unique_ptr instead of manual pointer management
- for zones and core patch types.
Easier data management, allows default destructors (for example)
- update TimeState access methods
- use writeTime() instead of old method name outputTime()
- use deltaTValue() instead of deltaT().value()
to avoids pointless construct of intermediate
- for simulations where the yPlus is needed for other purposes or
just for obtaining information on the patches it can be useful
to disable field writing and save disk space.
The 'writeFields' flag (as per some other function objects)
has been added control writing the yPlus volume field.
If unspecified, the default value is 'true' so that the yPlus
function object continues to work as before.
However, this default may change to 'false' in the future to align
with other function objects.
ENH: wallShearStress: support disable of field writing
- similar to yPlus, the write() method combines writing information
and writing the fields. The 'writeFields' flag allows some
separation of that logic.
- the default (uninitialised) value for edge connections of -1
could be confused with a tagged finiteArea patch, which used
(-patchid-1) encoding. This would lead to messages about erroneous
processor-processor addressing, but is in fact an mismatched edge
connection.
Now tag the finiteArea patch as (-patchid-2) to avoid this ambiguity
and correctly generate an "Undefined connection:" message instead.
Properly flush the VTP writers before raising a FatalError
to ensure that they are not prematurely truncated.
Open Point:
The base problem of "Undefined connection:" is largely related to
multiply-connected face edges (ie, from the underlying volume mesh).
Not easily remedied in the finiteArea generation.
TUT: basic finiteArea setup on motorBike
- with (nPollProcInterfaces < 0) it does the following:
- loop, waiting for some requests to finish
- for each out-of-date interface, check if its associated
requests have now finished (ie, the ready() check).
- if ready() -> call updateInterfaceMatrix()
In contrast to (nPollProcInterfaces > 0) which loops a specified
number of times with several calls to MPI_Test each time, the
(nPollProcInterfaces < 0) variant relies on internal MPI looping
within MPI_Waitsome to progress communication.
The actual dispatch still remains non-deterministic (ie, waiting for
some requests to finish does not mean that any particular interface
is eligible for update, or in any particular order). However, using
Waitsome places the tight looping into the MPI layer, which results
in few calls and eliminates behaviour dependent on the value of
nPollProcInterfaces.
TUT: add polling to windAroundBuildings case (for testing purposes)
- separate broadcast times from reduce/gather/scatter time
- separate wait times from all-to-all time
- support invocation counts, split off requests time/count
from others to avoid flooding the counts
- support 'detail' switch to increase the output information.
Format may change in the future
- replaced PstreamBuffers mechanism with globalIndex for both gather
and scatter operations. Use scheduled communication by default, but
is selectable.
- reduced communication with ensemble averaging and no-write
- in makeFaMesh, the serial fields are now only read on the master
process and broadcast to the other ranks. The read+distribute is
almost identical to that used in redistributePar, except that in
this case entire fields are sent and not a zero-sized subset.
- improved internal faMesh checking for files so that the TryNew
method works with distributed roots.
- functionality similar to that provided by foamToEnsight, foamToVTK
which allows blocking out patches (eg, outer walls, inlet/outlet)
that are not particularly interesting to visualize
- new submodels:
- 'equalBinWidth': groups data into bins of equal widths (previous behaviour)
- 'unequalBinWidth': groups data into bins of unequal widths
- output files per time-step are replaced with a single output file
- silently deprecates the input entries: 'setFormat' and 'formatOptions'
- replaced ad hoc handling of formatOptions with coordSetWriter and
surfaceWriter helpers.
Accompanying this change, it is now possible to specify "default"
settings to be inherited, format-specific settings and have a
similar layering with surface-specific overrides.
- snappyHexMesh now conforms to setFormats
Eg,
formatOptions
{
default
{
verbose true;
format binary;
}
vtk
{
precision 10;
}
}
surfaces
{
surf1
{
...
formatOptions
{
ensight
{
scale 1000;
}
}
}
}
- simplifies construction/inheritance
ENH: add {fa,fv}PatchField::zeroGradientType() static
- can be used to avoid literal "zeroGradient" in places
STYLE: adjust naming of pointPatch runtime selection table
- simply use 'patch' as per fa/fv fields
STYLE: add zero-size guard to patch constraintType(const word&)
When a finite-area case could not find an entry for "lnGradSchemes"
in the "faSchemes" file, the "corrected" scheme has been picked up
by default. Therefore, any changes in "snGradSchemes" entry will not
be read by finite-area models.
- barycentric coordinates in interpolation (instead of x/y/z)
- ease U (velocity) requirement.
Needn't be named in the sampled fields.
- default tracking direction is 'forward'
in cases with more than one primal or adjoint solvers
TUT: removed all occurances of useSolverNameForFields
from the optimisation tutorials since it is now set
automatically.
