How to design a Coutour for a special zone?
 

My simulation involves 2D with rudius of 0.15m and height of 12m (too long). Therefore, the whole plotting of coutour is difficult to watch in the Fluent postprocessing.

Now I want to just check the coutour for a finite zone,say, between 5.m and 6.8m. I know this can be done in Gambit by defining an additional zone. But now I wonder how this could be realized in Fluent GUI environment.

Please advise. Thanks.
