The Implementation of a Toroidal Limiter Model into the Gyrokinetic Code ELMFIRE

The ELMFIRE full f nonlinear gyrokinetic simulation code has been developed for calculations of plasma evolution and dynamics of turbulence in tokamak geometry. The code is applicable for calculations of strong perturbations in particle distribution function, rapid transients and steep gradients in plasma. Benchmarking against experimental reflectometry data from the FT2 tokamak [1,2,3] is being discussed and in this paper a model for comparison and studying poloidal velocity is presented. To make the ELMFIRE code suitable for scrape of layer simulations a simplified toroidal limiter model has been implemented. The model will be discussed and first results are presented.
