Notes. The first column names the model and in Col. 2 shows the used Langrangian multipliers. Columns 3−5 show different force-free consistency evaluations. Column 6 shows the ratio of NLFFF energy density to the corresponding potential energy density and Col. 7 the computing time.
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.
