Verification methodology for plasma simulations and application to a scrape-off layer turbulence code

I These equations are implemented in GBS, a 3D, flux-driven, global turbulence code with circular geometry, and the system is closed by the Poisson’s equation ω = ∇⊥φ [Ricci et al., PPCF 2012] I System is completed with a set of first-principles boundary conditions applicable at the magnetic pre-sheath entrance where the magnetic field lines intersect the limiter [Loizu et al., PoP 2012]: v‖i =± cs v‖e =± cs exp (Λ− φ/Te) ∂yTe =κT ∂yφ ∂yn =∓ n cs ∂yv‖i ω =− cos2α [( ∂yv‖i )2 ± cs∂ yv‖i ] ∂yφ =∓ cs∂yv‖i
