Thank you Mathieu for your suggestion, But if I understand correctly with this method I’m able to find only the value on the mesh points. Thus, if I change the mesh with finer or coarser elements the value and the location that I can find change. I would like to avoid this behavior, for this reason I would get the minimum value using the interpolated value on the slice. do you think it's possible to do it? can I manage this with a programmable filter (work from script without gui)?

I would get this point using the interpolation in order to avoid the ‘sensitivity’ to the mesh (in this way, theoretically, if I change the mesh the minimum should always remain at the same point). For this point I would like to get the three-dimensional position and the value of the scalar in question (pressure and/or velocity), maybe I can use the numpy functions in a programmable filter? https://docs.scipy.org/doc/numpy-1.14.0/reference/generated/numpy.amin.html But I have not idea of how use the interpolation… Thanks for the suggestions, Andrea _________________________________________________________________________________________________________________ Questo messaggio è da intendersi esclusivamente ad uso del destinatario e può contenere informazioni che sono di natura privilegiata, confidenziale o non divulgabile secondo le leggi vigenti.
