OOF2: The Manual
Time Step Statistics (StepStatistics) — Print time stepping statistics. For meaningful results, schedule this with Conditional/Every Time.
StepStatistics is a dubiously useful ScheduledOutput that gathers statistics
on the number and size of the time steps taken when solving a time dependent
problem. Since the same statistics are automatically printed to the
after every solution, this class is only useful if for some reason
you need those numbers saved in a file.
StepStatistics doesn't produce any output
until the time evolution is complete. However, it does need to be
invoked at intermediate times so that it can accumulate statistics.
This is done by setting
scheduletype to ConditionalOutputSchedule and
schedule to EveryTime in OOF.Mesh.Scheduled_Output.Schedule.Set.
