MODELING OF MULTIPHYSICS PROBLEM AND RESEARCH OF COUPLING RELATION

Classification methods are studied on coupling relations of multiphysics problems.Firstly a general formulation of two-field coupled problem is constructed.Based on it,five kinds of classification methods are described: interface coupling and field coupling,Bidirectional coupling and unilateralism coupling,Direct coupling and indirect coupling,differential coupling and algebraic coupling,source coupling,flux coupling,property coupling and geometry coupling.And then ten general coupled problems are studied according to these classification methods.Finally a MEMES problem is simulated to explain the application of the classification methods.
