Abstract
The scrape-off layer code EDGE2D has been extended to accommodate more than one impurity species [1]. The parallel transport coefficients ar e calculated from a 21 moment description using the method of reduced charge states (RCS). Simulations with carbon and helium as impurities have been carried out to validate the multi-species version of EDGE2D. It is shown that further use of RCS allows the reduction of the numbe r of momentum equations. The computing time is thereby substantially r educed. At the same time the code results show little difference betwe en using the reduced set of momentum equations and using the full set.
