] or numerical methods (finite element method, etc.) [9-10]. It is noteworthy that the two physical fields are not independent of each other. Multi-physics or coupling analysis enables data exchange between them in one-direction or bi-direction to ensure high computation accuracy [11-13]. For one-direction coupling, these physical models are solved in successive steps. The results of the first analysis......
