[Paraview] Exporting data from Paraview with connectivity after clipping/slicing

[Evan Kao]

Hello all,

I'd like to export the data with the topology information (preferably as a
.csv from a Spreadsheet View), especially after using the Slice and Clip
Filters.  This would require the original node IDs and cell
connectivities.  However, there appear to be a couple issues:

1.  The globalnodeids aren't retained after using a Filter, although this
can be (somewhat sloppily) circumvented by copying the globalnodeids with
the Calculator.

2.  The cell data does not appear to include any connectivity information
(i.e. node ids that make up the element).  How do I retrieve that data?

Thanks,
Evan Kao
