Class
    Foam::functionObjects::multiRegion
 
Group
    grpUtilitiesFunctionObjects
 
Description
    Wrapper that clones the supplied function object for each region.
 
    Simplifies the setup of identical post-processing requirements for
    multi-region cases.
    Applies the supplied function to all regions by default.
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    multiRegion
    {
        // Mandatory entries
        type    multiRegion;
        libs    (utilityFunctionObjects);
 
        function
        {
            // Actual object specification
            type    fieldMinMax;
            libs    (fieldFunctionObjects);
            fields  (<field1> ... <fieldN>);
        }
 
        // Optional entries
        regions     (region1 region2);
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                          | Type | Reqd | Deflt
      type       | Type name: multiRegion               | word | yes  | -
      libs       | Library name: utilityFunctionObjects | word | yes  | -
      function   | Function object sub-dictionary       | dict | yes  | -
      regions    | List of region names                 | wordList | no  | all
    \endtable
 
    The inherited entries are elaborated in:
