- instead of deciding beforehand if a surface format requires a separate
geometry file (or if a geometry file should be written if no fields were
written) now determine afterwards if something was written.
This improves the overall reliability (consistency) and is more
convenient for the caller as well.
- PtrDynList support for move append list:
can be used to concatenate pointer lists into a single one
- include resize in PtrDynList squeezeNull as being a natural
combination
- support sorting operations for pointer lists (PtrListOps)
- comparison operator, for sorting based on the position of the origin.
- allow modification of the origin.
- zero-initialise for null constructor: base components are vectors
and cheap to initialise.
- 'unfriend' the output operator: it uses public access methods
- remove writeGeometry() in favour of write() and make it pure virtual
so that all writers must explicitly deal with it.
- establish proxy extension at construction time and treated as an
invariant thereafter. This avoids potentially surprising changes in
behaviour when writing.
- this is a simple container for fields with i-j-k addressing.
It does not support field operations directly, but is primarily
intended to be used when assembling field information with i-j-k
logic. After assembly, the field can be transferred to a regular
field for normal operations. Eg,
IjkField<scalar> assemble({15, 16, 200});
// .. fill in i-j-k fields
Field<scalar> final(std::move(assemble));
assemble.clear(); // be pedantic

- While a rectilinear mesh can be created with blockMesh, not every mesh
created with blockMesh will satisfy the requirements for being a
rectilinear mesh.
This alternative to blockMesh uses a single block that is aligned
with the xy-z directions and specifications of the control points,
mesh divisions and expansion ratios. For example,
x
{
points ( -13.28 -0.10 6.0 19.19 );
nCells ( 10 12 10 );
ratios ( 0.2 1 5 );
}
y { ... }
z { ... }
With only one block, the boundary patch definition is simple and the
canonical face number is used directly. For example,
inlet
{
type patch;
faces ( 0 );
}
outlet
{
type patch;
faces ( 1 );
}
sides
{
type patch;
faces ( 2 3 );
}
...
- After a mesh is defined, it is trivial to retrieve mesh-related
information such as cell-volume, cell-centres for any i-j-k location
without an actual polyMesh.
STYLE: remove -noFunctionObjects from blockMesh
- no time loop, so function objects cannot be triggered anyhow.
- PtrList::release() method.
Similar to autoPtr and unique_ptr and clearer in purpose than
using set(i,nullptr)
- Construct from List of pointers, taking ownership.
Useful when upgrading code. Eg,
List<polyPatch*> oldList = ...;
PtrList<polyPatch> newList(oldList);
...
BUG: incorrect resizing method names (PtrDynList) in previously unused code
- this functionality was originally added to allow sampling of volume
fields onto a surface in order to perform calculations on them.
However, the sampling framework essentially mirrored the
sampledSurface, but was less complete.
It is now possible to store sampled surfaces on a registry and
do calculation with their fields. This is the preferred method,
and thus removing the surfMeshSample duplicate code.
- previously wrapped raw points/faces with a meshedSurfRef on input,
but now handle the raw -> meshedSurf logic directly within
surfaceWriter to avoid holding references to temporaries
Since the updated meshedSurfRef is now modifiable, it can be used
directly as a redirection mechanism within surfaceWriter.
- add explicit close() in destructor
- A negative expansion ratio is geometrically invalid and will
normally cause issues (FatalError).
However, we can trap this type of input and interpret it as the
inverse expansion ratio - ie, the expansion ratio in the opposite
direction. This can be especially convenient when generating a blockMesh
with a symmetrical expansion. It permits using the same expansion
ratio (with a sign change) instead of providing the reciprocal values
manually.
COMP: revert demand-driven point creation in blockMesh (db9b35b50d)
- appears to have caused a dangling reference on some systems
ENH: add a lightweight ijkAddressing class
- it can be used for an i-j-k to linear lookup of meshes or fields,
where applicable.
- avoid potential ambiguities in naming of mesh faces/edges
vs. block faces/edges
- additional methods characterizing the number of faces
(internal, boundary, total) associated with a blockDescriptor
- cellLabel() accessor and checkIndex() methods
- restore demand-driven behaviour of block, cache the calculated cells
and refactor generation of block boundary faces to improve potential
reuse.
