有限元的未来是多物理场耦合（The future of finite element is multi physics field coupling） With the rapid development of computer technology, finite element analysis (FEA) is more and more used in the field of engineering to solve the real engineering problems. These years, more and more engineers and applied mathematicians and physicists have proved that this method of solving partial differential equations (PDE) method can solve many physical phenomena, the partial differential equation can be used to describe the flow field and structural mechanics, etc.. The finite element method is used to transform these well-known mathematical equations into approximate digital images. Early finite elements were mainly concerned with a particular field, such as stress or fatigue, but in general, physical phenomena did not exist alone. For example, as long as exercise produces heat, heat in turn affects some material properties, such as electrical conductivity, chemical reaction rates, fluid viscosity, and so on. The coupling of such a physical system is what we call a multi physics field, and it is much more complex to analyze than to analyze a physical field alone. Obviously, we need a multi physics field analysis tool now. In the last century before 90s, due to the lack of computer resources, multi physics simulation only stays at the theoretical stage, finite element modeling is limited to the simulation of a single physical field, the most common is the heat transfer, fluid mechanics, and electromagnetic field simulation. The fate of finite element simulations seems to be the simulation of a single physical field. Now this situation has begun to change. After decades of effort, the development of computational science has provided us with a more agile, simple and fast algorithm, and a more robust hardware configuration, which makes it possible to simulate the finite element in many physical fields. The new finite element method provides a new opportunity for multi physics field analysis
