Notes. Indicated scatter is the 1σ deviation in the temporal fluctuation of the quantities. For the precise definition of the quantities, see text (Sects. 37) and formulas. For their derivation, data of the full simulation time of 38 000 s with a cadence of 250 s were used, except for rows 17–21 and 25–27 for which the cadence was 10 s.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
