Abstract(s)
The benefits of the usage of stationary over time-dependent solvers of COMSOL Multiphysics in
the modelling of DC discharges are explored and demonstrated using as examples glow and high pressure arc discharges; in particular, it is investigated whether time-dependent solvers can be used
for a systematic computation of different modes of these discharges. It has been found that most
modes of both glow and high-pressure arc discharges cannot be computed in the whole range of
their existence by a time-dependent solver. Further, time-dependent solvers are unsuitable for a
computation of all the states belonging to the retrograde sections of the current-voltage
characteristics of the modes, so the discharge manifests hysteresis, which, in principle, can be
observed in the experiment.
