Resumo(s)
Complex behavior can appear in the modeling of gas discharges even in apparently simple
steady-state situations. Time-dependent solvers may fail to deliver essential information in
such cases. One of such cases considered in this work is
the 1D DC discharge. The other case is represented by
multiple multidimensional solutions existing in the
theory of DC discharges and describing modes of
current transfer with different patterns of spots on the
cathodes. It is shown that, although some of the
solutions, including those describing beautiful self organized patterns, can be computed by means of a
time-dependent solver, in most examples results of
time-dependent modeling are at best incomplete. In
most examples, numerical stability of the time dependent solver was not equivalent to physical
stability.
