[Paraview] [EXT] Re: EXODUS: How to find nodes that are common to more than 1 sideset

[Dennis Conklin]

Utkarsh,

This is funny, because I just spent 6 days laboriously eliminating all the common nodes on 4 different models.  I don't think I have any bad meshes left.  And if I did I would not be able to share them with the list.  

Really, I just need an example of how to access side sets (block(4) of Exodus Reader) in a Programmable Filter
As in output=self.GetOutput()    SideSets=output.GetBlock(4)

After that I'm lost as to how to identify SSet by ID (name?) and how to access the actual values in the SSet.  Comparing them to find common nodes would be fairly easy if I just understood how to get to the SSets.

Say I have SSet "1201" and SSet "1202" and I want to compare them to see if they have any common nodes - the hard part is finding the right SSets and getting the nodes in them.

I remember going through this a while back when needing to access Block Names and never would have figured it out on my own.

Dennis

Do you have a dataset that demonstrates this? It may be easier to figure out what could work with a sample dataset at hand.
