Many space and industrial related technology development require modeling of complex plasma and flow physics applying hybridization of different continuum-and/or particle-based solvers. Examples may include plume analysis of reaction control thrusters on upper-stage rocket and satellite in orbit, rocket plume analysis at high altitude, ion thruster plume analysis, and plasma distribution in an etching chamber, to name a few. These studies often utilize solvers developed independently and integrate them in a non-self-consistent approach, which makes their applications and future extension highly inflexible. Thus, a highly flexible simulation platform, which allows easy addition and integration of different solvers with a self-consistent approach while maintaining efficient computation, is strongly needed to tackle problems with complex physics, such as flow/plasma in space related technology. In this paper, we report the development of a new C++ object-oriented multi-physics simulation platform named Rigorous Advanced Plasma Integration Testbed (RAPIT®) using unstructured meshes with parallel computing. The proposed RAPIT® can easily accommodate continuum-and/or particle-based solvers with some proper hybridization algorithm in a self-consistent way. For the former, it may include, but not limited to, the Navier-Stoke (NS) equation solver for general gas flow modeling and the plasma fluid modeling code for general low-temperature gas discharges. For the latter, it may include the particle-in-cell Monte Carlo collision (PIC-MCC) and the direct simulation Monte Carlo (DSMC) solvers. Some preliminary results of DSMC, PIC-MCC, NS equation and fluid modeling solvers based on RAPIT are presented in this paper. Future direction of the RAPIT is also outlined at the end of the paper.
