Class
    Foam::functionObjects::solverInfo
 
Group
    grpUtilitiesFunctionObjects
 
Description
    Writes solver information for a list of user-specified fields.
 
    Information written to file includes:
    - residual fields
    - solver type
    - initial residual
    - final residual
    - number of solver iterations
    - convergence flag
 
    Operands:
    \table
      Operand      | Type                | Location
      input        | -                   | -
      output file  | dat                 | postProcessing/<FO>/<time>/<file>(s)
      output field | volScalarField(s)   | <time>/initialResiduals:<outField>(s)
    \endtable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    solverInfoFO
    {
        // Mandatory entries
        type            solverInfo;
        libs            (utilityFunctionObjects);
        fields          <wordList>;  // (<field1> <field2> ... <fieldN>);
 
        // Optional entries
        writeResidualFields <bool>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                          | Type | Reqd | Deflt
      type         | Type name: solverInfo                | word | yes  | -
      libs         | Library name: utilityFunctionObjects | word | yes  | -
      fields       | Names of operand fields          | wordList | yes  | -
      writeResidualFields | Flag to write the initial-residual fields <!--
                   -->                                    | bool | no   | false
    \endtable
 
    The inherited entries are elaborated in:
     - \link functionObject.H \endlink
     - \link writeFile.H \endlink
