Multiphysics simulation is a computational methodology employed for the modeling and simulation of systems where multiple distinct physical phenomena are coupled and interact. This approach investigates the complex behavior of systems governed by interdependent processes from different physics domains, characterized by the simultaneous solution of their respective governing equations and the explicit accounting for their mutual influence. Its significance lies in providing a comprehensive predictive capability and a holistic understanding of complex engineered and natural systems where the interaction between physical fields is critical, enabling advanced analysis, design, and research across diverse fields.
