- previous only checked for clouds at the last instance and only
detected lagrangian fields from the first cloud.
Now check for clouds at all instances and detect all of their fields
as well.
- The reader module allows two levels of caching.
The OpenFOAM fvMesh can be cached in memory, for faster loading of
fields. Additionally, the translated VTK geometries are held in a
local cache. The cached VTK geometries should incur no additional
overhead since they use the VTK reference counting for their storage
management.
- 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.
