Fluid modeling of the Tokamak edge region is a well‐developed tool, employed both to understand the processes governing the edge plasma and to support the design of present and future experiments. However, this approach suffers from internal inconsistencies, due to the relevant effects induced by kinetic phenomena. The kinetic method is, in principle, general, but cannot be applied to regions of macroscopic size, due to its computational requirements. In this paper we apply both the fluid and kinetic approaches to similar plasma edge model problems, in order to point out their relative strengths and weaknesses.
