Abstract. The practicability of the Phoenical SHASTA FCT algorithm is examined for conditions close to those of a streamer (electric discharge) channel. An optimised, universal procedure is proposed which works practically in arbitrary conditions. As a test two examples are simulated, not specifying the electric field distribution. We treat self-consistent systems of "generalised" continuity equations. An easy to use FCT algorithm for 2D Cartesian and cylindrical coordinate systems is given. Several limiting techniques are explored, and it is found that the combination of 1D and 2D limiters without correctors is a suitable procedure.
