The 3D edge plasma transport code EMC3-EIRENE [1] was successfully adapted to the single null configuration of JET. A test bed with the well established 2D edge plasma code EDGE2D-EIRENE [2,3] was prepared to check the adaptation of the EMC3-EIRENE code and isolate any discrepancies when compared. While both codes solve essentially the same set of reduced Braginskii's fluid equations, they use very different numerical techniques: a 3D Lagrangian Monte Carlo method in EMC3 and a 2D Eulerian finite differences scheme in EDGE2D. The results should be very similar as both codes are iteratively coupled to the same kinetic neutral particle Monte Carlo code EIRENE [4]. We show that both codes are in a fairly good quantitative agreement regarding both midplane and target plasma profiles as well as transition from low to high recycling regime with increasing core plasma density.
