GfsEventStop is used to stop the simulation when steady-state is reached. This is done by monitoring the maximum change in a given variable at every locations between successive calls to GfsEventStop. If the absolute value of this change is smaller than or equal to a user-defined threshold the simulation is stopped.

The syntax in parameter files is:

[ GfsEvent ] V THRESHOLD ( DV )

where V is a variable, THRESHOLD a number and DV an optional variable name. If DV is given, the corresponding field contains the difference in V between successive calls.
