A bit crude, this cartoon nevertheless represents a major step forward in flare
modeling.
In this paper we saw for the first time a filamentary structure, each
with its "monolithic" flare loop for which an independent 1D
radiation-hydrodynamics simulation can be applied.
This obvious step forward had never been taken, and even to this day
the monolithic flare cartoon can still raise its head, most often nowadays in
the context of stellar flares
where indeed nobody has any observational constraints.
This was a logical step in grappling with the problem of multi-temperature
signatures in a flare, unresolved by our telescopes and not consistent
with a single loop.
For the Sun itself, of course, it is blitheringly obvious that a
monolithic model is a silly exercise.
There is a more colorful
modern version of this.
