We need the ability to see node and element ids in Python. For instance, I want to find PedegreeNodeId 1000. It doesn't exist in the Python interface. Here is how to test:

• ParaView 5.7.0-RC1, builtin server, Linux
• Open disk_out_ref.ex2, all variables on, apply.
• View/ Python view.
• disk=GetActiveSource()
• vars=disk.PointVariables.GetAvailable()

You see a list here. One is not GlobalNodeId, but it should be. Reason is, we want to do the following:

• sel=SelectPoints(“GlobalNodeId=1000”)
• e = ExtractSelection(Selection=sel)
• Show(e)
• Hide(disk)
• Render()

Or, more likely, we want to write this cell's data out to a .csv file, for post processing.
