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

[Moreland, Kenneth]

1. That's because there is no simple way to create new global IDs for the points generated by clip or slice in parallel. If you are running in serial, you can use the Generate Ids filter. If you are running in parallel you can use the D3 filter.

2. The CSV file format is not expressive enough to capture cell connectivity information. Use a different file format. Try the legacy VTK file format written in ASCII. Like CSV it is easy to both read by humans and parse by computers.

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

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
