Dear Mathieu,
Thanks for your suggestions.
If I have understood correctly, your method can works only in the case in which I have only a maxima like this case:

But if I have to find the local maxima in this case:

in which I have three different local max peaks, your method can works correctly?
Best regards,
Andrea

Dear Andrea
The range maximum value can be read directly in the information tab of your data, in the "Data Arrays" section.
Or you can directly create a new "Spreadsheet view", show your data in it and sort the data by clicking on your scalars array header, you will know the value et the localisation.
Best,
Mathieu Westphal

Dear all,
I need to find the local maxima of a scalar field on a slice in Paraview.
I need both the value of my scalar variable and also the tridimensional position of the local maxima.
Searching on the blog, I have found a possible vtk function:

Someone of you know some simpler and faster way to solve my problem (maybe using numpy library)?
I thank you in advance for all suggestions,
Andrea
