To whom it may concern,
I am trying to use the latest version of Paraview to extract velocity values at a series of probe points from a Simscale Simulation. I have a long list with the coordinates of all the points that I would need. Therefore, I created a csv file with three columns and the three coordinates of each point. I added it on Paraview, however, when I apply the filter “Table to points”, I get this error message: “Failed to locate the columns to use for the point coordinates”.
Could you please help me understand why I get this error message?
Thank you very much for your help in advance.
Kind regards,
Tommaso

Did you choose the arrays in the properties panel ?

Dear Mathieu,
Thank you very much for your help.
Yes, I selected only the cell array U and I also applied the extract block filter to it. I then opened my csv file, which created the table shown in the picture. The problem is when I apply the Table to points filter to the csv file.
Thanks again.
Kind regards,
Tommaso
