Normalization of output variables

Hi all,

how can I normalize the results with respect to the max of the results?

For instance, I have a contour plot of the Von Mises stress of a mechanical indentation simulation.

I want to compare this to a different simulation, so I would like to end up with a normalized contour plot.

I have tried using the Expression Builder but haven't succeeded yet.

I was trying something like STRESS / max( STRESS ), for all loadcases ==> T3.C7 / max( T3.C7, T3.C7 )

Does anyone have a clue?
 

Best regards,

Robbin
