Class
    Foam::functionObjects::runTimeControl

Group
    grpUtilitiesFunctionObjects

Description
    Controls when the calculation is terminated based on satisfying
    user-specified conditions.

    Optionally specify a number of write steps before the calculation is
    terminated.  Here, a write is performed each time that all conditions are
    satisfied.
