If you're using Tecplot 360 or Focus 2008R2 or newer, copy the 360/32-bit or 360/64-bit/locatezoneminmax.dll into your Tecplot "bin" directory. For older versions, use v10/locatezoneminmax.dll.
Edit your tecplot.add file and add this line:
$!LoadAddon "locatezoneminmax"
Start Tecplot
A option will appear in the File -> Tools menu. It should be pretty self-explanatory. There is a sample macro included.
Note:
It works ordered data and finite element data, but not polyhedral or polygons. It will also work for cell centered data, although there are few limitations with the cell-centered data (i.e. if you ask for the max and min of a variable that is node centered and there is cell centered data for the zone, it will give you the value at the cell center for ordered data but not give you any values for cell centers at the node location. If you ask for cell centered data all nodal variables for both Ordered and Finite element zones are interpolated to the cell center. Also, it is setup to copy and paste the other values directly into a spreadsheet. It is pretty self explanatory.
