Development of a Grid-Based Gyrokinetic Simulation Code

A new grid-based code is being developed for solving the gyrokinetic equation in tokamak geometry. This development builds on the experience gained with the CYGNE project [M. Brunetti \textit{et. al}, Comp. Phys. Comm. \textbf{163}, 1 (2004)], which solved the electrostatic drift-kinetic equations in a cylindrical system using a semi-Lagrangian approach. This new code makes use of efficient and flexible software modules optimized for parallel platforms. Preliminary results in reduced geometry, in particular slab and cylindrical, will be presented.
