Ah. Using 'duplicates' changes the name (adds ::1, ::2, etc). You can
use a glob in the plot definition to grab all of them.

To run the test multiple times, you'd just repeat the Flent invocation
(or use the batch facility and the 'repetitions' keyword). That will
produce a bunch of data files that you then plot at once in a separate
plot definition.
