Hello,

I am currently running cases based on OpenFOAM-1.6-ext.
In postprocessing, I am interested in monitoring the pressure fluctuations in a certain region within the full computational domain.
Included in the controlDict is:

Code:
functions
(
minMax
   {
       //type of function object
       type     fieldMinMax;

       //where to load it from (if not already in solver)
       functionObjectLibs ("libfieldFunctionObjects.so");

       //function object enabled flag
       //enabled        true;

       //log to output (default=false)
       //log    false;

       //write information to file (default=true)
       //write  true;

       outputControl    outputTime; //outputTime or timeStep

       mode     component; //magnitude or component

       outputInterval   1;

       //fields to be monitored - runTime modifiable
       fields
       (
        p
        U
       );
   }
);
This generates a file, fieldMinMax.dat, below:

Code:
# Time  field   min     max
50      p       -9.24249        19.687
50      U       (-2.91335 -2.87667 -4.10693e-16)        (10.6055 2.85288 3.66516e-16)
100     p       -16.6352        19.1588
100     U       (-5.19331 -2.5366 -3.92782e-16) (10.5135 2.28499 3.48259e-16)
In another (older) post,
HTML Code:
http://www.cfd-online.com/Forums/openfoam/147062-extracting-data.html
I saw the same code also spit out the x,y,z coordinates of the min and max values at each written time.

With that background, the two questions are:
1. Does anyone know how to get the locations associated with the min and max values?
2. Is it possible to limit the scope of the computational domain with a shape (for example, with a rectangular prism) and only "look" within that region for the min and max values? If so, does the shape need to be defined within an OpenFOAM dictionary or can the shape be defined with CAD and somehow imported?

Thanks!
