Gyrokinetic simulations

The gyrokinetic formalism [1][2] is based on first principles and provides a valuable tool for investigating low frequency turbulence in fusion plasmas. The Theory Group at the Laboratorio Nacional de Fusión collaborates with the Barcelona Supercomputing Center and the Max Planck IPP at Greifswald for the development and exploitation of the EUTERPE global gyrokinetic code.
The code EUTERPE has recently been benchmarked against the TORB code [3][4][http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5491114 in both linear and non-linear simulations [5].
