[Paraview] Examples of Field Variables Manipulation for Exodus Multi-block datasets

[Dennis Conklin]

All,

I can't find a good example of manipulating Field Variables (Global Variables) in Exodus Multi-block datasets.

For instance, I wrote a filter to calculate the total_volume of a mesh.   Currently I print this out to the screen.  I would like to add a Field variable of Total_volume but I have no idea how to do this.

Does anyone have an example of how to access (read) field variables and/or how to add one.

Thanks for any hints

Dennis
