In the first part of this paper we present multifluid model calculations of marfe instabilities in a simple geometry. Assuming carbon as the dominant impurity, the time evolution of the 2D Marfe is followed and typical e‐folding times and their variation with the poloidal and radial heat conductivities are determined. In part two of this paper we present a scrape‐off layer simulation in a typical x‐point geometry using a simplyfied hydrogen recycling model and again carbon as impurities. Other impurity species can be treated as well.
