A multiscale model for an improved description of radial particle transport described by the density continuity equation in large-scale plasma edge simulations for tokamak fusion devices is presented. It includes the effects of mesoscale drift-fluid dynamics on the macroscale profiles and vice versa. The realization of the multiscale model in form of the coupled code system B2- ATTEMPT is outlined. A procedure employed to efficiently determine the averaged mesoscale terms using a nonparametric trend test, the Reverse Arrangements Test, is described. Results of stationary, self-consistent B2-ATTEMPT simulations are compared to prior simulations for experiments at the TEXTOR tokamak, making a first evaluation of the predicted magnitude of radial particle transport possible.
