How to get the average value for the top 10% ranked output value for a predefined Named Selection? In post processing, it would take only the 10% top ranked output value (e.g. NLPLWK) in a predefined Named Selection (Mesh,Nodes,Face) and plot it. Then it would calculate the average of those 10% shorted values with their corresponding node without including the max value as it may be an outlier.
