functionObjects. Supports 'enabled' flag but none of the other options
'timeStart', 'timeEnd', 'outputControl' etc.
Note that any 'writeControl adjustableRunTime' will still be in
operation and will limit the wanted time step to account for the
- write interval and - timestep adjustment speed (time step cannot
change too quickly).
Example of function object specification to manipulate the time step:
