Time Step
To achieve optimal efficiency for these multi-year runs, the time
step was varied with season and forcing conditions as determined by
trial and error. Although ECOM-si is not restricted by the gravity
wave CFL condition, it is limited by the advective CFL condition. During
the spring and summer months in particular, the time step needed to
be decreased. During the winter, the time step was usually 414 s
(108 steps per 
tidal cycle),
except for a few short periods generally coinciding with winter storms.
During the summer, the time step was usually 207 s (216 steps per
tidal cycle).
