[Paraview] Looping over blocks in a multiblock data set and printing to a table or graph

[Sandeep Jella]

Hi Utkarsh, this works perfectly!

I have a related question...

I created a custom filter that I'd like to call from within the loop (over
the blocks).  Being able to call other filters within the loop would
tremendously save time...is there such a possibility?

Many thanks again for your  fast response earlier,

Sandeep.
