Abstract:
This study develops a CUDA C++-based 1D3V particle-in-cell/Monte Carlo collision (PIC/MCC) parallel simulation model for Capacitively Coupled Plasmas (CCP). The model introduces a novel particle management method that enables efficient addition and deletion of particles in GPU memory, ensuring that all solution processes are executed in parallel on the GPU, thereby avoiding time losses associated with frequent CPU-GPU communication. Furthermore, the proposed model incorporates a realistic Secondary Electron Emission (SEE) model based on Secondary Electron Yield (SEY), rendering the simulation results more physically realistic. The proposed model has been validated against benchmark cases, significantly reducing solution time while ensuring computational accuracy, with the majority of cases completing within several minutes to hours.
