Class
    Foam::functionObjects::fieldMinMax

Group
    grpFieldFunctionObjects

Description
    This function object calculates the value and location of scalar minimim
    and maximum for a list of user-specified fields.  For variables with a rank
    greater than zero, either the min/max of a component value or the magnitude
    is reported.  When operating in parallel, the processor owning the value
    is also given.

    Example of function object specification:
    \verbatim
    fieldMinMax1
    {
        type        fieldMinMax;
        libs ("libfieldFunctionObjects.so");
        ...
        write       yes;
        log         yes;
        location    yes;
        mode        magnitude;
        fields
        (
            U
            p
        );
    }
    \endverbatim

    \heading Function object usage
    \table
        Property     | Description             | Required    | Default value
        type         | type name: fieldMinMax  | yes         |
        write        | write min/max data to file |  no      | yes
        log          | write min/max data to standard output | no | no
        location     | write location of the min/max value | no | yes
        mode         | calculation mode: magnitude or component | no | magnitude
    \endtable

    Output data is written to the file \<timeDir\>/fieldMinMax.dat
