142145 - Performance Analysis of AutomataScales to Support Early Design Decisions 

In this paper, we present a comprehensive study and performance analysis on the AutomataScales simulations method focusing on electric propulsion systems for deep space missions. These applications require precise and time efficient simulations. However, the computational capability and energy required for these complex simulations are expensive and time consuming, leading to challenges in deep space scenarios where resources are limited. The AutomataScales method combines discretization techniques with cellular automata, offering a powerful tool to model complex multiphysics interactions with lower computational time and memory usage. The method depicts intricate and accurate behaviors in various types of particle trajectory (ionized particles, primary and secondary electrons) and plasma physics (particle collision and ionization). It provides a scalable and adaptable framework for multiphysics simulations with almost real-time simulation (0.1 second per time step). A key aspect of our research is the computational efficiency of AutomataScales. Our results show that the method can achieve up to 36.9 times faster, and 2.1 times less physical memory (random-access memory or RAM) compared to commercial simulation tools such as COMSOL Multiphysics Simulation Software. This substantial reduction in computational resources make AutomataScales more efficient and accessible for researchers to explore broader design variables in their early design process with or without computational constraints.
