Abstract:This review simply summarizes geodynamo models, including the control equations, dimensionless scheme, initial and boundary conditions, the numerical methods, the scaling laws, and so on. MoSST model is taken as an example to show the results of geodynamo numerical model. Though in the geodynamo numerical simulation there exist many problems and challenges, it is still an indispensable method to study the geomagnetic field. With the improvement in the computing power in the near future, the geodynamo numerical simulation will achieve great development and will provide powerful supports for understanding the geomagnetic field.
