Hi mate, how goes it?
How do you set the ghost level to be one rather than default zero then?
Have you written your own downstream filter to update the number of
ghost levels? If so any tips?
If you know the name of a global node ID array in the input dataset, set
that name with this method...
What I have done is used D3 internally in my reader to partition the data
and always have just 1 ghost level. This could mean issues if more were
needed but it's not necessary for the usual post-processing tasks of users.
To add global ids just create the array and call SetGlobalIds on your
Hello,
Since the data is essentially structured (rectilinear grids), I think
the best way to get the global/local mapping is to use extent
information. Specifically, you need the whole extent of the grid and
the global extent of each partition. Then from the global IJK of a
point or cell, and the
Many thanks for that. I perform some threshold stuff early on, so
basically I'm working with unstructured grids pretty much from zero. I
think I need to try to populate the ghost cells using the approach Ken
suggested, but I'm not sure how to do that both from a conceptual point of
view - I'd

Perhaps an easy solution is to append a GlobalCellID and
GlobalNodeID before thresholding. To the best of my knowledge,

Hi Andy,
I've had a few problems with D3. The limitation I find is that global node
ids are slow to generate and the point merging (I think) is only performed
in single precision. Also, remember that everything will be redone each
time the number of ghost levels that are requested changes -
