This paper presents a recently developed particle simulation framework, PIFE-PIC, a 3-D Parallel Immersed Finite Element (IFE) Particle-in-Cell (PIC) model for particle simulations of plasmas. This framework applies the recently developed non-homogeneous electrostatic IFE-PIC algorithm, which is designed to handle complex plasma-material interface boundary conditions associated with irregular geometries using a Cartesian-meshbased PIC. 3-D domain decomposition is used in both electric field-solve and particle-push to distribute the computation among multiple processors. A validation case simulating the sheath of a dielectric sphere immersed in a stationary plasma is carried out to demonstrate the capability of the code.
