- has the selected values directly and use these lookup names to store
directly into a hash. This replaces several parallel lists of
decomp information etc and makes it easier.
- as originally intended years ago, but never actually done.
- use 'foamPvCore' instead of 'vtkPVReaders' to avoid potential name
collisions with any 'vtk*' files and since we may reuse these
functions in other foam-paraview modules (not just readers).
STYLE: use same font size/colour for patch-names as for point-numbers
BUG: repair issue with single time-step
- paraview time-selector returns '0' as the requested time if there is
only one time step. However, if we have skipped the 0/ directory,
this single time step is likely a non-zero value.
- use "-pvMAJ.MIN" suffix for similarity with the paraview convention
- use sentinel file to ensure clean change of intermediate targets
- ensure all library files are being properly removed
- although this is not the final desired form, since it uses
individual pqPropertyWidget customizations (ie, ugly layout, too
many bits of code), but is an interesting intermediate solution
that may be useful in other contexts.
For example, to mesh a sphere with a single block the geometry is defined in the
blockMeshDict as a searchableSurface:
geometry
{
sphere
{
type searchableSphere;
centre (0 0 0);
radius 1;
}
}
The vertices, block topology and curved edges are defined in the usual
way, for example
v 0.5773502;
mv -0.5773502;
a 0.7071067;
ma -0.7071067;
vertices
(
($mv $mv $mv)
( $v $mv $mv)
( $v $v $mv)
($mv $v $mv)
($mv $mv $v)
( $v $mv $v)
( $v $v $v)
($mv $v $v)
);
blocks
(
hex (0 1 2 3 4 5 6 7) (10 10 10) simpleGrading (1 1 1)
);
edges
(
arc 0 1 (0 $ma $ma)
arc 2 3 (0 $a $ma)
arc 6 7 (0 $a $a)
arc 4 5 (0 $ma $a)
arc 0 3 ($ma 0 $ma)
arc 1 2 ($a 0 $ma)
arc 5 6 ($a 0 $a)
arc 4 7 ($ma 0 $a)
arc 0 4 ($ma $ma 0)
arc 1 5 ($a $ma 0)
arc 2 6 ($a $a 0)
arc 3 7 ($ma $a 0)
);
which will produce a mesh in which the block edges conform to the sphere
but the faces of the block lie somewhere between the original cube and
the spherical surface which is a consequence of the edge-based
transfinite interpolation.
Now the projection of the block faces to the geometry specified above
can also be specified:
faces
(
project (0 4 7 3) sphere
project (2 6 5 1) sphere
project (1 5 4 0) sphere
project (3 7 6 2) sphere
project (0 3 2 1) sphere
project (4 5 6 7) sphere
);
which produces a mesh that actually conforms to the sphere.
See OpenFOAM-dev/tutorials/mesh/blockMesh/sphere
This functionality is experimental and will undergo further development
and generalization in the future to support more complex surfaces,
feature edge specification and extraction etc. Please get involved if
you would like to see blockMesh become a more flexible block-structured
mesher.

- remove old VTK_CONVEX_POINT_SET code, since VTK_POLYHEDRON exists
since several years
ENH: improve robustness of paraFoam script
- only check the relevant plugin types,
fallback to native reader if needed/possible.
