Three-dimensional modelling of drift-wave turbulence Original Research Article

An EPIC (Extended Particle-in-Cell) scheme is developed to model electrostatic drift-wave turbulence in three space dimensions. An existing two-dimensional code that treats magnetic shear and non-adiabatic effects is adapted to incorporate the ICEx algorithm, that enables instability-free numerical modelling of complex wave phenomena without a timestep restriction. Successful simulations of drift-wave interactions are presented.
