Find Cell Data - Based on csv file

ParaView Support
1

I want to extract only cells below the white line. The white line is from a csv file I used “TabletoPoint” to get the plot. The csv file has two columns with x and y locations.

I have an idea but idk how to execute it. For every cell in the mesh :

if (Cell_x == CSV_x && Cell_y <=CSV_y) : Keep that cell
Else: Remove that cell

My bad, this cannot work. You need to implement this in a programmable filter I’m afraid.

Okay, thanks for the reply. How to get started with the programming part of ParaView?
