Create Field Output using Maximum

[cbPVme]

Is there a way to find a maximum value between field outputs? I am trying to create a field output from fields that takes the difference in principal stresses P1-P2, P2-P3 and P3-P1 then plots the maximum of those 3 values. I don't see any operator that takes maximum or minimum

You’ll probably have to script this if you don’t want to do it manually since the only built-in options related to your goal are finding maximum values over all frames and creating envelope plot (maximum from all section points in each element).
