- prior to sampledSurface supporting different interpolation schemes a
workaround means was used to simulate cellPoint -> face
interpolation, with averaging of vertex interpolation.
We instead now use cellPoint interpolation directly for the face
values when 'interpolate=true'.
- normally findInstance will 'bottom out' with the constant directory
while doing its reverse time search. This mechanism however fails
when searching for negative start values (if there are none in the
list). Add additional logic for this so that constant will also be
used in these situations.
Note: to have decomposePar work for all times, may need the -constant option
to trigger the proper time list.
- construct from positions
- reset positions, minEdgeLen, find grid index
ENH: add accessor for obtaining the size of a single i-j-k dimension
- eg, obtain the 'i' dimension with any of these methods:
ijkAddr.size(vector::X)
ijkAddr.sizes().x()
ijkAddr.sizes()[0]
- 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
- Extended runTimePostProcessing to include access to "live"
simulation objects such a geometry patches and sampled surfaces
stored on the "functionObjectObjects" registry.
- Add 'live' runTimePostProcessing of cloud data.
Extracts position and fields from the cloud via its objectRegistry writer
- For the "live" simulation objects, there are two new volume filters
that work directly with the OpenFOAM volume fields:
* iso-surface
* cutting planes
Both use the VTK algorithms directly and support multiple values.
Eg, can make multiple iso-levels or multiple planes parallel to each
other.
- When VTK has been compiled with MPI-support, parallel rendering will
be used.
- Additional title text properties (shadow, italic etc)
- Simplified handling of scalar-bar and visibility switches
- Support multiple text positions. Eg, for adding watermark text.
