finding coordinates of max/min values inside domain

Hi,

I'm trying to find the coordinates of the max/min stress values in a specific domain. I can find the values of the actual max/min but I'm having a hard time finding the actual coordinates. I can use 3d plot group to find the max/min coordinates of the structure as a whole but can't seem to find the coordinates of the max/min stress values for a particular domain. How do I accomplish this?
