PIFE-PIC: Parallel Immersed Finite Element Particle-in-Cell for 3-D Kinetic Simulations of Plasma-Material Interactions

This paper presents a recently developed particle simulation code package PIFE-PIC, which is novel three-dimensional (3-D) parallel immersed finite element (IFE) particle-in-cell (PIC) model for simulations of plasma-material interactions. framework based on the nonhomogeneous electrostatic IFE-PIC algorithm, designed to handle complex interface conditions associated with irregular geometries using Cartesian mesh-based PIC. Three-dimensional domain decomposition utilized both field solver IFE and operations in PIC distribute computation among multiple processors. A orbital motion-limited (OML) sheath dielectric sphere stationary plasma carried out validate profile performance package. Furthermore, large-scale charging at lunar crater containing 2 million cells (10 FE/IFE cells) about 1 billion particles, running 20,000 steps 154 wall-clock hours, presented demonstrate high-performance computing capability PIFE-PIC.
