Abstract In the analysis of the 2D coupling electromagnetic-fluid-thermal fields, which the meshes in electromagnetic domain don't match the meshes in the fluid-thermal domain, the mapping method of the node data need to be studied. In order to map electromagnetic losses to fluid-thermal field accurately, this paper proposed the fast projection algorithm and the radial basis function (RBF) scheme, and presented the mixed method combing the advantages of the two proposed methods. Based on the examples with analytical solutions and the leakage magnetic field mapping of a converter transformer, the feasibility of the three methods were verified, the effects of the grid density on the mapping algorithm accuracy was discussed, the mapping accuracy of the three methods were compared, and the computational efficiency of the fast projection algorithm and the RBF schemes were studied. The result shows that three methods have advantages and disadvantages. For different applications, it is necessary to choose a proper mapping algorithm according to the model and grid features. Above research lay a foundation for the 2D coupling electromagnetic-fluid-thermal fields.

Key words： Data mapping fast projection algorithm radial basis function mixed method
