The nonConformalCHT template case is designed to help create a conjugate
heat transfer (CHT) simulation in which fluid and solid regions are
coupled with non-conformal coupled (NCC) interfaces. It includes an
Allmesh script which provides example commands to generate the meshes
for the fluid and solid regions using the 'snappyHexMeshConfig' utility,
and to generate NCC interfaces using 'createNonConformalCouples'. The
remaining workflow to configure and run the CHT simulation is similar to
the 'singleFluidCHT' template case.
-closedDomain domain does not contain inlets or outlets
-minDimCells <int> number of cells in the shortest direction, e.g. 10
-region <name> specify alternative mesh region
The faces in the mesh are renumbered to ensure upper-triangular ordering, the
faces in the faceZones must also be renumbered accordingly.

A number of bugs have been fixed relating to cases in which multiple NCC
patches are locally edge-connected, and/or are edge-connected across a
processor boundary.
This serves as an example of the creation of a private method. It no
longer needs to convert the Function1 argument to user time, following
the addition of generalised unit conversion.
Non-named unit conversions are now written in a single set of square
brackets, with colons used to separate the sets of exponents and
multipliers. So, for example, a named unit conversion of [rpm] gets
converted to a non-named [0 0 -1 0 0 0 0 : 0 1 : 0.10472] (i.e.,
[time^-1 : angle : 0.10472]).
Previously, multiple sets of square brackets were used to separate the
sections, so the above example would have been written as
[0 0 -1 0 0 0 0][0 1][0.10472]. The problem with this is that '][' is
not distinguished in the token parser from '] ['. Combined with the fact
that the later sections are optional, this makes reading pairs or lists
of these objects impossible. The new format is, by comparison,
unambiguously delimited in all contexts.
This change may break the restart of a case in which unit conversion
entries have been written out. It is unlikely to require modification to
an initial configuration as named unit conversion entries (such as [rpm]
and [MPa] and [l/min]) are unaffected.
This phase model solves multiple physical species, but fixes the
temperature to a constant value. This combination does not conserve
the energy of the phase.
This prevents inconsistent field data being cached.
Note that the stitcher still does not cause old-time fields to be
stored. Stitching is not considered an update (in time) to a field's
value. It is a pure mapping, and it applies similarly to both current
and old-time fields.

Residuals are only available once some equations have been solved, so it
is not valid for this function to execute until the end of the first
timestep.
This also prevents a bug in which the residuals function trggers the
construction of a Residuals mesh object during the writing of the file
header. This only happens on the master process, and therefore leads to
the master having more objects in its database than the other processes.
If this results in the object table being resized then this can change
the iteration order, which can in turn break mapping procedures (in NCC,
topology change, mesh-to-mesh mapping, ...) which rely on fields being
accessed from the database in a consistent order.
The 'select' control can now take the value 'patches' in which case a
'patches' control will be used to specify a list of patches, rather than
just a single patch. The 'patches' and 'patch' controls now also both
support wildcards.
which can be opened in ParaView, for it to interpret series of VTK files
generated by OpenFOAM post-processing. This script supercedes the
'foamSequenceVTKFiles' script which generates a directory of indexed
soft-links which is no longer needed. 'foamSequenceVTKFiles' is
nevertheless maintained for workflow backward-compatibility.
in a sequence of VTK files. Instead of loading a group of VTK which
uses their index as time, the respective .vtk.series file can be loaded
which relates each file to the correct time.
