- 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.
- construct from MinMax, optional start index for identity factory
method to match Foam::identity()
- use GREAT instead of VGREAT in inverted scalarRange.
Consistent with boundBox - to reduce the potential of overflow
if calculating the span.
- add min()/max() methods to labelRange
