Class
    Foam::solvers::functions
 
Description
    Solver module to execute the \c functionObjects for a specified solver
 
    The solver specified by either the \c subSolver or if not present the \c
    solver entry in the \c controlDict is instantiated to provide the physical
    fields needed by the \c functionObjects.  The \c functionObjects are then
    instantiated from the specifications are read from the \c functions entry in
    the \c controlDict and executed in a time-loop also controlled by entries in
    \c controlDict and the \c maxDeltaT() returned by the sub-solver.
 
    The fields and other objects registered by the sub-solver are set to
    NO_WRITE as they are not changed by the execution of the functionObjects and
    should not be written out each write-time.  Fields and other objects created
    and changed by the execution of the functionObjects are written out.
 
    When restarting from a time directory which does contain the \c subSolver
    fields the optional \c controlDict entry \c subSolverTime may be provided to
    specify which time the \c subSolver should be instantiated for, after which
    time is reset to \c startTime for the restart.
