Description
Summary:In this paper, we report on simulations that have recently been carried out using the EUTERPE gyrokinetic code. The scaling of the code has been studied up to 20 000 processing elements. Linear and nonlinear simulations of ion temperature-gradient instabilities have been carried out in screw-pinch geometry, and the results are compared with those previously obtained using the TORB code, finding a good agreement. The influence of a finite β on the growth rates of instabilities and on the zonal flows in a screw-pinch has also been studied. The results are compared with previous ones.
