We derive and implement a set of radially global gyrokinetic equations including compressional magnetic fluctuations into the turbulence code GENE, and benchmark against local flux-tube scenarios of a standard tokamak case [Görler et al., PoP 23, 072503 (2016)]. The new code is then compared with local simulations at the LAPD high-β experimental parameters and magnetic reconnection in the solar corona with realistic β and hydrogen mass ratio.
Due to the use of finite-element radial base functions, the perpendicular magnetic potentials Ax,y need to be computed separately. This decouples B// from its gyroaveraged quantity 〈B//〉, thus a new gyroaverage procedure for the compressional magnetic field is implemented.
