Hello,
I’ve imported a geometry into paraview that already has some solution data. I want to filter the Mesh into different regions using the Threshold Filter, group those regions together into a new object, and finally program each region to have a different value ex: Temperature: 500K
How can I do the last step programatically? Can someone point me to modifying cell/point properties like temperature?
Thanks

For each part you want to threshold :
`Threshold + Calculator`
Then, select all the calculators and :
`GroupDataSet`
