Class
    Foam::regionModels::regionFaModel

Description
    Base class for area region models.

Usage
    Example of the model specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        region          <word>;
        active          <bool>;

        <model>Coeffs
        {
            // subdictionary entries
        }

        // Optional entries
        infoOutput      <bool>;

        // Inherited entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property   | Description                         | Type  | Reqd | Deflt
      region     | Name of operand region              | word  | yes  | -
      active     | Flag to activate the model          | bool  | yes  | -
      infoOutput | Flag to activate information output | bool  | no   | false
    \endtable
