I am a very new user of Paraview - and am just learning its capabilities. I am importing a series of CSV files - creating points and Delaunay polygons - and then using the Calculator filter to create vectors to plot with the Glyph tool. But when I use the calculator - one of the "Point Data" fields is not numeric - and when I write my formula (which does not use the non-numeric field) and hit "Apply" - thje Output message says
ERROR: In ..\..\..\..\source\VTK\Graphics\vtkArrayCalculator.cxx, line 304 vtkPVArrayCalculator (000000000B39EAE0): Invalid array name: 'Name' (the name of the non numeric field is "name"). I tried renaming this field in the input file - and this didn't work. So I removed the non-numeric field completely from the input file - and the calculator did work. So, I have the option of editing all of my input files - so they don't have non-numeric fields - or there is some way of getting Paraview to not choke on this field - or I'm missing something obvious right in front of my nose? Any help is appreciated. Thanks. New2PV
