[Paraview] storing output calculated by python running in parallel - write to a file? (UNCLASSIFIED)

[Utkarsh Ayachit]

Simon,

If you're saving out data generated by a pipeline (which can include
Programmable filter or Python calculator), then you should use
CreateWriter(http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/paraview.simple.html#paraview.simple.CreateWriter)
to create a writer and then write the data out -- akin to "Save Data"
in ParaView.
