Pullback scheme implementation in ORB5
Alexey Mishchenko, Alberto Bottino, Alessandro Biancalani +9
The pullback scheme is implemented in the global gyrokinetic particle-in-cell code ORB5 [S. Jolliet et al, Comp. Phys. Comm., 177, 409 (2007)] to mitigate the cancellation problem…
Parallelization of JOREK-STARWALL for non-linear MHD simulations including resistive walls (Report of the EUROfusion High Level Support Team Projects JORSTAR/JORSTAR2)
S. Mochalskyy, M. Hoelzl, R. Hatzky
Large scale plasma instabilities inside a tokamak can be influenced by the currents flowing in the conducting vessel wall. This involves non linear plasma dynamics and its interact…
Numerical comparison between a Gyrofluid and Gyrokinetic model investigating collisionless magnetic reconnection
O. Zacharias, L. Comisso, D. Grasso +3
The first detailed comparison between gyrokinetic and gyrofluid simulations of collisionless magnetic reconnection has been carried out. Both the linear and nonlinear evolution of…
