Development and Parallelization of Gyrokinetic PIC Code for MHD Simulation
نویسندگان
چکیده
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) code. The performance of the Gpic-MHD on the massive-parallel computer is studied. No saturation of the speed-up factor is observed as the number of cores (processors) increases.

Abstract. The hybrid MHD-Gyrokinetic model has been proven to be very successful in describing the coupling between Alfvén waves and energetic particles and their mutual interaction in toroidal devices. HMGC, the nonlinear MHD-Gyrokinetic code originally developed at the Frascati laboratories, is being currently extended to include new physics. In this paper we will present the first simulation...

Gyrokinetic particle-in-cell (PIC) simulation is an important tool for studying low-frequency (! !ci) plasma instabilities and the associated transport of particles and heat in tokamaks. In spite of the e ciency gained by not following ion cyclotron motion, more e ciency is needed in performing simulations on a transport timescale: using 1 million particles in a system of 64 128 32 grid cells, ...

A global plasma turbulence simulation code, ORB5, is presented. It solves the gyrokinetic electrostatic equations including zonal flows in axisymmetric magnetic geometry. The present version of the code assumes a Boltzmann electron response on magnetic surfaces. It uses a Particle-In-Cell (PIC), δf scheme, 3D cubic B-splines finite elements for the field solver and several numerical noise reduc...
