We report the recent upgrade of gyrokinetic toroidal code (GTC), which enables global simulations coupling the core and scrape-off layer (SOL) across the separatrix by using cylindrical coordinates with field-aligned particle-grid interpolation. With the interfacing with EFIT equilibrium and LamyRidge equilibrium, GTC code can be applied for the global geometry simulation for both tokamak and field reversed configuration (FRC). The fully kinetic particle trajectory integrator is also implemented in cylindrical coordinates by using Boris push method with conserving energy and canonical angular momentum.
