Development and Parallelization of Gyrokinetic PIC Code for MHD Simulation

In order to simulate global magnetogydrodynamic phenomena in tokamaks, a new gyrokinetic PIC (particle-in-cell) code, Gpic-MHD, is developed. Gpic-MHD is written in cylindrical geometry and has single-helicity (two-dimensional) version and multi-helicity (three-dimensional) version. The kinetic internal kink mode is successfully simulated and compared with the results of gyro-reduced-MHD (GRM) ...

Petascale Parallelization of the Gyrokinetic Toroidal Code

The Gyrokinetic Toroidal Code (GTC) is a global, threedimensional particle-in-cell application developed to study microturbulence in tokamak fusion devices. The global capability of GTC is unique, allowing researchers to systematically analyze important dynamics such as turbulence spreading. In this work we examine a new radial domain decomposition approach to allow scalability onto the latest ...

A Parallel Pic Code for a Hall Thruster Simulation

Fluid codes are widely used to model Hall thrusters because of their simplicity and low computational demands. However, they have not been successful in describing all the physics of Hall thrusters. On the other hand, PIC codes (Particle In Cell) are powerful for simulating microscopic phenomena. Their drawback is the requirement in the number of particles in order to achieve good results. This...
