Class
    Foam::fa::option
 
Description
    Base abstract class for handling finite area options (i.e. \c faOption).
 
Usage
    Minimal example by using \c constant/faOptions:
    \verbatim
    <userDefinedName1>
    {
        // Mandatory entries (unmodifiable)
        type              <faOptionName>;
 
        // Mandatory entries (runtime modifiable)
        region            <regionName>;
 
        // Optional entries (unmodifiable/runtime modifiable)
        <faOption>Coeffs
        {
            // subdictionary entries
        }
 
        // Optional entries (runtime modifiable)
        active            true;
        log               true;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property         | Description                   | Type  | Reqd | Dflt
      type             | Name of operand faOption      | word  | yes  | -
      region           | Name of operand region        | word  | yes  | -
      <faOption>Coeffs | Dictionary containing settings of <!--
                    --> the selected faOption settings | dictionary | no | -
      active   | Flag to (de)activate faOption         | bool  | no   | true
      log      | Flag to log faOption-related info     | bool  | no   | true
    \endtable
 
Note
  - Source/sink options are to be added to the right-hand side of equations.
