The FEFI (full electrons, full ions) code is at present the only fully nonlinear ’total-f’ electromagnetic gyrokinetic model which can address the steep gradient edge region of tokamak plasmas without any separation between background and fluctuating components of the dependent variables. Scale separation is to be achieved within the model on a high resolution spatial grid, with a spatially dependent velocity space grid for treatment of large temperature contrasts. The electromagnetic field responses to the dynamics of electron and ion gyrocenters include the self consistent magnetic equilibrium. The code is currently parallelised up to 512 CPUs and can be run for medium sized domains. The goal is to have it fully capable for global computation of turbulence and transport for ITER. Within DECI it is planned to simulate the entire pedestal region (edge-to-core transition) of the ITER tokamak.
