How to extract out the maximum value in a domain?

Hi All,
I am working on a structural mechanics problem. I modeled a contact pair. However, I just care about the maximum principal stress in one geometry/domain. How can I extract out this maximum value. I know you can fairly easy get the maximum value of all domains from the volume plot. But how to separate one domain out and plot it?
Thanks
Qiulin

Hi
in V4 you have different operators to extract maxima, in 3.5 you often need to use matlab.
To select one particular domain you can multiply your operant by a bolean
my_integration_equation*(dom==3)
for domain identifier = "3"

Good luck

Hi Ivar,
Thank you very much for your help.
Can you explain more? I am a new user of COMSOL. Where are the related buttons and how to set them up? I just want to plot one domain and see the highest value in it.
Thanks again.

Hi
I can really only suggest then to go carefully through the exercices set up in the doc, it takes some time to catch the subtilities of COMSOL, exercicing is really the best way to catch it, and start very simple, then later only, add physics and take the "complex cases" Try to take shool bok examples that you can verify analytically, and look at the equations COMSOL is using (see equation view on in the preferences)
